A TINY PROBLEM WITH HUGE IMPLICATIONS—

NANOTECH AGENTS AS ENABLERS OR

SUBSTITUTES FOR BANNED CHEMICAL

WEAPONS: IS A NEW TREATY NEEDED?

Evan J. Wallach*

“[T]he Law of Nations . . . allows not the taking the Life of an Enemy,

by Poison; which Custom was established for a general Benefit, lest

Dangers should be increased too much. . . . Humanity, and the Interests

of [the] Parties, equally require it; since Wars are so frequent and . . .

the Mind of Man, ingenious in inventing Means to do hurt . . . .”

—Hugo Grotius1

INTRODUCTION

In 2005, the U.S. Army’s Environmental Policy Institute

(“AEPI”) posed a scenario and a question. The AEPI offered this

provocative picture of future combat:

Consider this scenario: A column of soldiers moves

through the close confines of a city. Because of the potential

for hostilities, the soldiers are maintaining a MOPP2 level 2

2. Mission-oriented protective posture, or “MOPP” as it is commonly referred, is a

military acronym that is used to specify different levels of protective gear that personnel

wear in toxic environments. See U.S. ARMY, THE WARRIOR ETHOS AND SOLDIER COMBAT

SKILLS 13-10, § 13-26, Field Manual No. 3-21.75(FM21-75) (Jan. 28, 2008), available at

posture and chemical detectors are deployed in the column.

Suddenly from the surrounding rooftops, there are gunshots

and a number of canisters are hurled off the roof tops.

Within moments, portions of the column are enveloped in

hazy cloud and within a minute or so the soldiers closest to

the canisters are twitching and salivating uncontrollably and

even those soldiers who were able to don their protective

masks and gloves are showing the same symptoms. Soldiers

from the rear of the column move forward having easily

cleared the roof tops with automatic weapons fire in an effort

to aid their comrades. Although the chemical agent

detectors show no evidence of conventional chemical agents,

they administer nerve agent antidotes in accordance with

their training, but the victims worsen and quickly die. Within

a few minutes, even the fully garbed soldiers find themselves

salivating beyond control and trembling. Soon, they too are

dead; the chemical agent detectors remain silent.

What happened here is but one possible result of

nanotechnology harnessed to do the will of terrorists.

Traditional chemical agents are largely prohibited by treaty

or agreement and the precursors of traditional agents can be

tracked. As nanotechnology advances, it will be possible to

design materials that act like chemical agents, in this case a

cholinesterase blocking agent, but are not classed as chemical

agents under any existing protocol, do not trigger existing

chemical agent detectors and in any case do not respond to

known nerve agent antidotes and, because of their small size,

can penetrate protective fabrics and even mask filters.3

available at http://www.aepi.army.mil/internet/nanotech-industrial-revolution.pdf

(emphasis added). The United States Army’s Environmental Policy Institute’s (“AEPI”)

assumption here appears to be that the nanomaterials used in the scenario are

something other than the chemical agents and their precursors listed in the Chemical

Weapons Convention (“CWC”). See discussion infra Part I. Rather, they “act like”

chemical agents. The AEPI seems to be describing only one potential type of

nanoweapon—a device which mimics the effects of chemicals on the human body by

means other than a direct chemical reaction. These devices are what the AEPI calls

“nanomachines” in its recommendations section. See id. at 27.

860 FORDHAM INTERNATIONAL LAW JOURNAL [Vol. 33:858

In short, the AEPI posited that nanomaterials which mimic

banned chemical agents (“nanomimics”)4 might be developed

and used in combat. The Institute recommended that someone

should determine “if nanomachines are chemical weapons under

the provisions of the Chemical Weapons Convention.”5 This

Article attempts to do exactly that.6 The results are interesting

and, in most instances, very clear. Existing treaties certainly cover

both nanoparticles of banned chemical weapon materials and

4. This Article uses the word “nanomimic” to refer to devices that causes the same

result as a banned poison, toxin or other chemical substance. In biology, mimicry occurs

when one species imitates another. See WOLFGANG WICKLER, MIMICRY IN PLANTS AND

ANIMALS 8 (R.D. Martin trans., 1968). Batesian mimicry,

is thought to occur when a rare harmless species evolves to resemble closely an

abundant noxious model. It gains protection from its predators which cannot

tell the difference between model and mimic, and since they tend to

encounter models rather than mimics when searching for food, they associate

the colour pattern of the model with the nasty experience, and tend to avoid it

in future.

FRANCIS GILBERT, THE EVOLUTION OF IMPERFECT MIMICRY IN HOVERFLIES 1 (2004),

available at http://eprints.nottingham.ac.uk/96/1/ImperfectMimicry.pdf. Hoverflies

that resemble bees or wasps are an example. See id. at 4–5. In Mullerian mimicry,

“several noxious species evolve to resemble each other, and hence all benefit by a

reduction in predation.” Id. at 1.

6. In a broad sense, the question was raised even earlier by a professor of

engineering at West Point:

The importance of ethics and professional responsibility in engineering design

cannot be overemphasized when weapons of mass destruction can be

inexpensively and straightforwardly created by anyone with modest specialized

knowledge and equipment. Arms control style agreements offer one option for

halting the spread of dangerous technology applications, but these agreements

will not include non-state terrorist and radical militant groups. However, arms

control treaties would still be important tools to restrain the dark side of

emerging technologies, and the Army could provide the prime forces for

verification of compliance with international treaties and agreements. In the

case of non-state sponsored militant groups, the Army could find itself a major

Homeland Defense Force team member, working closely with intelligence

organizations to enforce United Nations sanctioned ethical standards and

controls on research into unmistakably dangerous technologies; including

infectious biotechnology products, malicious information technology viruses,

and other nefarious weapons.

nano-sized devices designed to carry such particles.7 Because,

however, answers regarding potential development of

nanomimics are not entirely clear,8 the recommendation of this

Article is that states parties9 may wish to amend the 1993

Chemical Weapons Convention (“CWC”)10 to clearly cover as yet

undeveloped nanomachines.11

Nanotechnology is a relatively new field of knowledge

studying and applying the development and application of very

small particles of matter.12 While it has implications across a wide

range of science including chemistry, physics, and biology,13 it is

currently being publicly developed and deployed for medical treatment, particularly in

oncology. See infra Part I.C.

8. Although, as this Article demonstrates, a legal argument for noncoverage of

nanomimics by existing treaties requires an interpretation of the law at least at the edge

of bad faith.

9. This Article is directed to whether states are bound under international law, and

whether certain conduct by them might constitute war crimes. Several of the scenarios

and discussions cited mention the possibility of using chemical weapons by terrorists.

This Article does not deal directly with actions by terrorists, but since, in any definition,

terrorists are nonstate actors, and generally commit what would be war crimes if

committed by a state, the analysis is perfectly applicable, albeit in a multistep fashion.

involve some living parts, this Article does not extensively examine the separate

biological aspects of nanotechnology and its interplay with the Biological Weapons

widely regarded as crossing many of the traditional scientific

boundaries of those fields of study.14 Nanotechnology is of

particular interest to students of law and warfare15 in three

respects: First, nanoparticles of known chemical warfare agents

or precursors to those agents may have different effects on

protective gear and on human physiology than conventionally

sized particles of those agents.16 Second, nano-sized carriers,

similar to those currently under development for

chemotherapy,17 may deliver target doses of chemical agents to

targeted cells in the human body.18 Third, speculative19 literature

predicts that the eventual production of robots on the nanoscale

will be possible some day.20 In effect, these nanoscale robots

would enter the human body, penetrate cells, and cause them to

act in a fashion similar to the effects of currently banned

chemical weapons.21

The underlying thesis of this Article is that while smallersized

particles and separate nano-sized carriers of known agents

are clearly covered by the CWC, nanomimics are not as squarely

within the relevant provisions. The bulk of this Article deals with

that question. In light of that analysis, however, it is important to

outside the scope of this Article. Additional research in the field might prove fruitful for

further study.

U.S. Army has raised the question, and because history has shown that humanity’s

destructive impulses are often the most fruitful for the progress of scientific knowledge.

recognize that the CWC incorporates the 1925 Geneva Gas

Protocol,22 which prohibits, in part, that “the use in war of

asphyxiating, poisonous or other gases, and of all analogous

liquids, materials or devices.”23 An extremely strong argument can

therefore be made that the CWC facially bans nanomimics. That

argument, however, depends on the intention of the states

signatory to the treaties.24 In determining the intention of a

party, recourse may be had to the drafting history and working

papers, contemporaneous general commentary by the legal

community and the press, the events of the recent history before

the treaty was signed, and, of course, signing statements and

reservations.25 Some of that material is, however, mixed,

contradictory, vague, lost, or was intentionally omitted in original

“completing a process which began almost 50 years ago when the United States

proposed at Geneva a ban on the use in war of ‘asphyxiating, poisonous or other gases’”

and stated that “the United States has long supported the principles and objectives of

the Geneva Protocol.” Gerald Ford, U.S. President, Geneva Statement on the Protocol

to refer specifically to a protein produced by some higher plants, certain animals, and

pathogenic bacteria, which is highly toxic for other living organisms. Such substances

are differentiated from the simple chemical poisons and the vegetable alkaloids by their

high molecular weight and antigenicity.” Id. at 1968.

publications.26 It is, in short, a law professor’s nirvana, for it

leaves room for endless analytical speculation.

Despite the invitation to woolgather, this Article is limited to

the tightest possible analytical approach. Part I begins with

definitions of chemical and biological agents within existing

treaties, and of nanoproducts, including those existing beyond

presently-known technical capabilities, but which are at least

reasonably conceivable (“nanobots”).27 Part II provides an

overview of treaty law that is potentially applicable to nanobots. It

first examines current treaties that are facially applicable to

nanoproducts. Because of the possibility that the “all analogous

26. For example, in his introductory comments at the 1922 Naval Conference

former U.S. Secretary of State Elihu Root stated that the language introduced by the

U.S. delegation was borrowed from the Treaty of Versailles, which ended World War I

between most of the Allies and Germany. See Edwin James, Hughes Proposes Gas Ban, N.Y.

TIMES, Jan. 7, 1922, at 1. In fact, the U.S. proposal did substantially track the language of

the Treaty of Versailles, but it also differed in respects vital to this analysis from the other

treaties ending the Great War with Austria, Hungry, Bulgaria, and Turkey. See RAYMOND

L. BUELL, THE WASHINGTON CONFERENCE 207–09 (1922). Was Root intentionally

misleading the conferees, did he honestly miss the distinctions, or did he recognize

them, but think they were so unimportant as to not be worth mentioning? All those

questions have a bearing on the analysis in this article and on future applications of the

treaty banning chemical weapons on the 21st Century. See discussion infra Part

II.A.1.d.ii.

27. It has been suggested that the term “nanobots” is inherently misleading, and

that a more accurate phrase is “enhanced nanomaterials.” Another suggestion was that,

for the purposes of this Article, “nanobots” are indistinguishable from specifically

engineered viruses. The Author disagrees that the term “nanobots” has no utility, but

acknowledges that clearly it is fraught with discord. One problem in the area is that

there are some assumptions based on prior speculation, initially envisioned by Kim Eric

Drexler, about what is essentially self-replication of nano-sized machines. See K. ERIC

DREXLER, ENGINES OF CREATION: THE COMING ERA OF NANOTECHNOLOGY 53–63 (1987).

The dispute is fascinating, and beyond the Author’s capacity as a layman in the field of

nanotechnologyto evaluate, but it is largely irrelevant to the question posed by the AEPI

that is answered here. “Nanobot” for purposes of this Article is a device on the

nanoscale which is capable of mimicking the effect of chemical nerve agents, see

discussion infra Part I.A.4, but is neither a product of chemical processes, nor a

biological agent as banned by the BWC. See discussion infra Part IV.A.3. This Article will

therefore not address other pertinent critiques of the term, particularly those related to

Brownian motion (movement of particles suspended in fluid), and the numbers of

individual devices which might be necessary to constitute a lethal dose. It bears note,

however, that the speculation in this Article is largely based on assumptions emerging

from medical research, particularly in the field of cancer research. See discussion infra

Part I.C. In any case, when one deals with potential weapons development it is always

wise to err on the side of expecting the worst, for “[t]here are more things in heaven

and earth, Horatio, than are dreamt of in your philosophy.” WILLIAM SHAKESPEARE,

. . . devices” language of the 1925 Geneva Protocol28 bans

nanobots, the Article examines very closely the origin,

application, and meaning of that language. A close inspection

necessarily involves considerable discussion of pre-1914 treaties,

as well as the battles, weapons, tactics, and legal analyses in World

War I, and the mass reaction to them, which resulted in a series

of treaties implicating chemical weapons after the war ended.

Part II then looks briefly at other treaties, conventions, and

doctrines of international law that may impact the use of

nanobots. Part III briefly examines current theories regarding

good faith treaty interpretation and their implications for the

utilization of antique (but not necessarily antiquated) doctrines

and documents to interpret current law. Part IV then applies the

current treaties to nanoproducts, both existing and potential, in

light of the preceding discussion, and then turns to a discussion

of whether a new treaty, or modifications or clarifications to

existing treaties, are advisable.

I. CURRENT DEFINITIONS OF CHEMICAL AGENTS,

BIOLOGICAL AGENTS, AND NANOSYSTEMS

The most modern sources of law controlling the acquisition

and use of chemical and biological weapons are the 1972

Biological Weapons Convention (“BWC”)29 and the 1993 CWC.30

Given past experiences, the drafters of the more recent

conventions relating to biological and chemical weapons were

specific in their coverage.31 Accordingly, current law quite

explicitly bans “[m]icrobial or other biological agents, or toxins

whatever their origin or method of production, of types and in

quantities that have no justification for prophylactic, protective

or other peaceful purposes” and “[w]eapons, equipment or

means of delivery designed to use such agents or toxins for

28. See Geneva Protocol, supra note 23 and accompanying text.

29. See Biological Weapons Convention, supra note 13.

30. See Chemical Weapons Convention, supra note 10.

31. As will be discussed below, the history of arms control treaties is often also a

history of their evasion.Often, that evasion was justified by what the evading party

characterized as distinguishing factors of the weapon that it used. See, e.g., infra Part

II.A.1.c (discussing Germany’s use of chlorine gas in 1915).

866 FORDHAM INTERNATIONAL LAW JOURNAL [Vol. 33:858

hostile purposes or in armed conflict.”32 It is also unequivocal in

its prohibition of all chemical weapons.33

It is particularly important to note that the CWC covers any

“chemical which through its chemical action on life processes

can cause death, temporary incapacitation or permanent harm to

humans or animals . . . regardless of their origin or of their

method of production.”34 Accordingly, a broad class of current or

immediately potential nanoproducts may be covered by the

􀀃

32. Biological Weapons Convention, supra note 13, art. I(1)–(2).

33. See Chemical Weapons Convention, supra note 10, art. I. The CWC contains a

very specific definition of “chemical weapons”:

(a) Toxic chemicals and their precursors, except where intended for

purposes not prohibited under this Convention, as long as the types and

quantities are consistent with such purposes;

(b) Munitions and devices, specifically designed to cause death or other

harm through the toxic properties of those toxic chemicals specified in

subparagraph (a), which would be released as a result of the employment of

such munitions and devices;

(c) Any equipment specifically designed for use directly in connection

with the employment of munitions and devices specified in subparagraph (b).

Id. art. II(1). “Toxic chemicals” are defined with a similar level of specificity:

Any chemical which through its chemical action on life processes can cause

death, temporary incapacitation or permanent harm to humans or animals.

This includes all such chemicals, regardless of their origin or of their method

of production, and regardless of whether they are produced in facilities, in

munitions or elsewhere.

Id. art. II(2). The CWC is written broadly enough to cover existing and undiscovered

applications and substances. The continuing work of the Organization for the

Prohibition of Chemical Weapons demonstrates that this level of breadth was intended

by the drafters. See discussion infra Part IV.A.3.b; see also S. TREATY DOC. NO. 103-21, at 8

(1993) (“The intention of this broad definition [of chemicals] is to prohibit all known

and unknown, and future toxic chemicals in types and quantities that cannot be justified

for permitted purposes”). But cf. Robert Pinson, Is Nanotechnology Prohibited By the

Biological and Chemical Weapons Conventions?, 22 BERKELEY J. INTL L. 279, 294 (2004)

(arguing that it may be possible to use nanotechnology for conventional weapon

purposes under the broad exceptions permitted by the CWC).

34. Chemical Weapons Convention, supra note 10, art. II(2). The CWC’s definition

of chemical weapons differs from the way other international agreements define

weapons. Typically, “a weapon is usually considered to be the entirety of its components,

and characterized by certain more or less objective criteria . . . that would allow for

distinction between those types of weapons covered by the treaty and those not

covered . . . .” WALTER KRUTZSCH & RALF TRAPP, A COMMENTARY ON THE CHEMICAL

WEAPONS CONVENTION 23 (1994). Under the CWC, by contrast,“ each of the

components of a chemical weapons system in itself already has to be regarded as the

prohibited weapon.” Id. at 24 (emphasis added); see also WALTER KRUTZSCH AND RALF

TRAPP, VERIFICATION PRACTICE UNDER THE CHEMICAL WEAPONS CONVENTION (1999)

(commenting on the verification provisions under the CWC).

CWC; others might not. To comprehend potential applications

one must first understand the language of nanotechnology.35

A. Nanotechnology and Molecular Nanotechnology

Nanotechnology is, broadly put, the science of the very

small. In Military Nanotechnology, Jurgen Altmann states that

nanotechnology, including nanoscience, “is about investigating

as well as manipulating matter on the atomic and molecular

level. At this level, the borders between the disciplines physics,

chemistry, [and] biology vanish, including their sub-,

intermediate and applied fields, such as materials science,

mechanics, electronics, biochemistry, genetics, [and]

neurology.”36 A useful discussion of general concepts is found in

Nanotechnology and Homeland Security:

[Nanotechnology] is the application of nanoscience to useful

devices. Nanoscience . . . is the science that deals with objects

with at least one dimension between one and one hundred

nanometers in length, a size range called the nanoscale. A

nanometer is one one-billionth of a meter . . . . [W]hy does

[nanoscience] get so much hype, and why is it so important

for national defense and national security? The first reason is

that nanoscale objects . . . are a special kind of small.

Individual atoms are around one-fifth of a nanometer. The

size of almost all molecules . . . lies within the nanoscale,

because it is the smallest level within which functional matter

can exist . . . . This means that . . . we can make materials

whose amazing properties can be defined in absolute terms

[and] it is the scale at which the quirky quantum mechanical

properties of matter and its more familiar mechanical

properties (such as hardness, temperature and melting

point) meet. At the nanoscale it is possible to take advantage

of both sets of properties . . . .37

biological macromolecules such as enzymes and receptors—

hemoglobin, for example, is approximately 5 nanometers in

(“As with many technologies, the medical applications may be adapted for offensive

purposes. Manipulation of biological and chemical agents using nanotechnologies could

result in entirely new threats that might be harder to detect and counter than existing

[chemical and biological weapons]. New agents may remove previous operational

difficulties of biological warfare, such as effective delivery of the agent. The large surface

area of nanoparticles, relative to their overall size, increases their toxicity when inhaled.

Advanced capabilities may include the use of genetic markers to target specific organs in

the body, or an ethnic group, or even a specific individual . . . . The design of new agents

42. In 1914, a British scientist, Henry Dale, described the physiological effects of a

substance called acetylcholine. In 1921, Otto Loewi, an Austrian scientist, provided the

first proof that acetylcholine transmitted messages from one nerve cell to another, and

from those cells to organs such as the heart. Loewi later demonstrated acetylcholine is

broken down by an enzyme called cholinesterase. JONATHAN B. TUCKER, WAR OF NERVES

CHEMICAL WARFARE FROM WORLD WAR I TO AL-QAEDA 52 (2006). In essence,

[t]he arrival of a nerve impulse at the junction between a nerve and a muscle

cell induces the release from the nerve ending of molecules of acetylcholine,

which diffuse across a narrow gap called the synapse and stimulate receptors

on the surface of the muscle cell, triggering a series of biochemical events that

cause the muscle fibers to contract. Under normal conditions, cholinesterase

enzymes in the synapse immediately break down the acetylcholine and halt the

stimulation of the receptors, allowing the muscle fibers to relax. . . . [Nerve

gases] inhibit[] the action of cholinesterase . . . [thus freezing] the

biochemical on-off circuit in the ‘open’ position, allowing [toxic acetylcholine

build-up]. Because acetylcholine plays multiple roles in the peripheral,

autonomic, and central nervous systems, excessive amounts give rise to diverse

physiological effects [including violent, uncontrollable spasms of skeletal

muscles followed by paralysis, excessive salivation, vomiting, bronchial

constriction, and seizures]. Nerve agents can induce death by asphyxiation

through three different mechanisms: constriction of the bronchial tubes,

suppression of the respiratory center of the brain, and paralysis of the

breathing muscles.

history of the development and deployment of nerve gases.

which are associated with using biocomponents (such as

realize that nanotechnology applications can become very

provocative.”55

Indeed, the U.S. Army has considered the implications for

some time, at least in the area of biological weapons. In 1999,

Lonnie Henley raised the possibility of several novel biological

warfare applications56 including, “subject to prevailing law and

arms treaties,” selective agents that can distinguish friend from

foe, triggered agents that harm only in specific situations “[n]ew

ways to kill or incapacitate opponents,” “[p]enetration aids” to

bypass defenses or immunities, or “[a]nti-material agents.”57

Henley did not consider the chemical warfare implications, per

se.

Legal implications of nanotechnology in the unconventional

weapons context, have been raised before.58 Many of the

discussions have been narrowly directed to a particular regulatory

approach,59 are downright utopian,60 or are relatively limited in

natural environment, nor would they have to be capable of

reproducing themselves.”62 It is interesting to compare this

statement with Ummat, Sharma, Mavroidis, and Dubey’s

discussion of bio-nanobots.63 Key questions arise about treaty

coverage depending on whether these bots are, in fact, bugs, for

they may, depending on attributes of life,64 fall within the BWC,

the CWC, or in the cracks between.

Reynolds also notes that “[t]he same technology that could

selectively destroy cancer cells could instead target immune or

nerve cells, producing death or further debility.”65 Others have

raised similar issues:

[N]ano-bots may in the future travel through the blood

stream seeking and killing off cancer cells, or may assist with

the regeneration of healthy cells. At the opposite extreme, it

may also be possible to use nano-bots for military purposes to

detect motion in a field and transmit signals many miles

away, or to achieve “programmable” genocide. Drexler’s

vision is that such robots, known as “assemblers,” will have

the ability to self-replicate . . . and [be able] to work in

unison to build macro-scale devices en masse. While

commentators such as Whiteside and Smalley have dismissed

these ideas as futuristic hype, nanotechnology nevertheless

captures one exciting conceptual possibility.66

which distinguishes active organisms from inorganic matter, including the capacity for

growth, functional activity and the continual change preceding death. A diverse array of

living organisms (life forms) can be found in the biosphere on Earth, and properties

common to these organisms—plants, animals, fungi, protists, archaea, and bacteria—are

a carbon-, and water-based cellular form with complex organization and heritable

There is intensifying awareness around the world of the need

to balance the obvious advantages of globalization with its

increasingly apparent disadvantages. Regarding arms

control, this is demonstrated by a growing need to balance

the benefits of greater and more diffuse flows of people,

goods, technologies and knowledge—including those

relevant to developing weapons of mass destruction

(WMD)—with a greater ability to monitor and prevent their

misuse towards illicit and violent ends. This conundrum

applies across a widening spectrum of current and emergent

technologies—such as nuclear technologies, but especially in

the biological sciences, including genetic engineering,

synthetic biology and nanotechnologies—and, as discussed

in this volume, raises new and vexing questions about the

appropriate balance between the greater diffusion and the

appropriate control of such technological advancements.67

From a feasibility standpoint, the most likely application of

this smallness to chemical warfare is the reduction of existing

banned chemical weapons to a size possibly undetectable by

current means and unfilterable by current protective gear,

and/or the enhancement of effects of current weapons because

of increased toxicity. Those “nano-enhanced” agents are a

three immediate areas of concern: the application of nanotech

Congressional Research Service has noted that scientific

concern74 about nanoparticles is based in part on some of the

very properties that researchers hope to exploit for medical

purposes:

The small size of nanoparticles may allow them to pass easily

through skin and internal membranes. This raises questions,

however, of whether exposure may be effectively confined to

targeted tissues . . . . It is too soon to know whether such

questions are serious cause for concern, but there is scientific

evidence that some nanoparticles may be hazardous. For

example, certain nanoparticles are known to be toxic to

microbes, and EPA has reported some studies that have

found nanoparticles generally (but not always) are more toxic

than larger particles of identical chemical composition.75

Questions remain, however, at the most basic levels:

Even among researchers [who focus] on toxicity, there is no

agreement about which data might be useful . . . . Scientists

have not yet determined which physical-chemical properties

(for example, size, shape, composition, stability, or electric

charge) will be most important in determining . . .

toxicological properties.76

The toxicological properties of nanomaterials is in some

ways the most urgent concern for enforcers, and at the same time

perhaps the least interesting from a juridical viewpoint. There

seems to be no possible argument that nano-enhanced poisons

are any less banned under the current CWC Annexes than they

would be at any other size.77 More interesting though, is the

current emergence of nanodelivery systems in what may be a first

step towards autonomous nanomachines.

C. Nanobots as Delivery Systems

The most likely immediate scenario for application of

nanotechnology78 to chemical warfare is as a delivery system

based on the chemotherapy model. As noted in The Economist:

76. Id. at 7. This information might indicate a need to at least amend the appendix

to the CWC, which is, of course, done on an ongoing basis in any case. Interesting issues

arise when nanotech meets toxicity. For example, the U.S. Toxic Substances Control

Act, 15 U.S.C. § 2601 (2006), excludes nanomaterials that are not “chemical

substances,” and it defines a “chemical substance” as “any organic or inorganic

substance of a particular molecular identity” that is not a mixture. Id. § 2602(2). Given

this definition, “it might not be clear whether certain nanoparticles consisting of a core

inorganic material coated by an organic material would” be covered. SCHIEROW, supra

note 75, at 12. That sort of legal question demonstrates the potential difficulty of

determining coverage by international conventions if they are not read, as was clearly

intended, with a very wide reach indeed. See discussion infra notes 326–36 and

accompanying text.

77. The possibility exists, of course, that some of those chemicals may have

beneficial attributes in, say, chemotherapy, but exceptions already exist within the CWC

regime for certain dual use materials. See Chemical Weapons Convention, supra note 10,

arts. II(9), IV.

2010] NANOTECH AGENTS 879

[A] second generation of nanoparticles has entered clinical

trials. Some are so good at hiding their contents away until

they are needed that the treatments do not merely reduce

side-effects; they actually allow what would otherwise be

lethal poisons to be supplied to the tumour only. Others do

not depend on drugs at all. Instead, they act as beacons for

the delivery of doses of energy that destroy cancer cells

physically, rather than chemically.79

It is also worth noting that the authors in Bio-Nanorobotics: The

State of the Art extensively discuss inorganic molecular machines

which may have applicability as chemical agent delivery systems:

In the past two decades, chemists have been able to create,

modify and control many different types of molecular

machines. Many of these machines carry a striking

resemblance with our everyday macroscale machines . . . .

Not only this, all of these machines are easy to synthesize

artificially, and are generally more robust than the natural

molecular machines. Such artificial chemical machines are

controllable in various ways [or in more than one way]. A

scientist can have more freedom with respect to the design of

chemical molecular machines depending on the

performance requirements and conditions.80

A great deal of work, both private and governmental, is

going into research about delivery systems.81 The publicly

available literature is largely devoted to various forms of cancer

research; although other medical applications have been

discussed.82 If such carriers are used to deliver poisons or toxins

banned under the CWC, their facial illegality for that use again is

quite clear.83 The carriers themselves, however, may very well

have dual usage,84 and the other uses may be to the medical

benefit of humanity.

The National Cancer Institute (“NCI”) of the National

Institutes of Health explains how nanotechnology is applicable in

battling cancer:

Nanoscale devices are one hundred to ten thousand

times smaller than human cells. They are similar in size to

large biological molecules (“biomolecules”) such as enzymes

and receptors. As an example, hemoglobin, the molecule

that carries oxygen in red blood cells, is approximately 5

nanometers in diameter. Nanoscale devices smaller than 50

nanometers can easily enter most cells, while those smaller

than 20 nanometers can move out of blood vessels as they

circulate through the body.

Because of their small size, nanoscale devices can

readily interact with biomolecules on both the surface of

cells and inside of cells. By gaining access to so many areas of

the body, they have the potential to detect disease and

deliver treatment in ways unimagined before now. And since

biological processes, including events that lead to cancer,

occur at the nanoscale at and inside cells, nanotechnology

offers a wealth of tools that are providing cancer researchers

with new and innovative ways to diagnose and treat cancer.85

The NCI then goes on to explain specifically how

nanotechnology can be used directly in cancer therapy both as a

target for external radiation and as a carrier agent for nanosize

does of chemical therapies:

Nanoscale devices have the potential to radically change

cancer therapy for the better and to dramatically increase the

number of highly effective therapeutic agents. Nanoscale

constructs can serve as customizable, targeted drug delivery vehicles

capable of ferrying large doses of chemotherapeutic agents or

those chemicals which pose a high risk to the goals of the CWC, including precursor

chemicals used to produce nerve agents or mustard agents. Schedule 2 lists those

chemicals that generally are not produced in large commercial quantities for

nonmilitary purposes and pose a significant risk to the purpose of the CWC. Schedule 3

lists dual-use chemicals which may pose a risk to CWC goals but also have legitimate

commercial purposes and are widely produced. See Chemical Weapons Convention,

therapeutic genes into malignant cells while sparing healthy

cells, greatly reducing or eliminating the often unpalatable

side effects that accompany many current cancer therapies.86

Thus, much of the nano-related research currently being

conducted in medical laboratories is both exciting and terrifying.

It offers both the promise of advanced medical treatment for

previously incurable diseases, and the threat of more effective

means for delivery of lethal chemicals as weapons of mass

destruction. The same may be generally said of nanobots.

Nanobots which would function solely to mimic existing or

future CWC banned chemicals, however, are in a class by

themselves. It is those hypothetical weapons which are the core

subject of the question posed by the AEPI, and which are a core

subject of this Article.

D. Nanomimics of Existing Banned Weapons

Finally, there is the AEPI’s scenario of “materials that act

like chemical agents, . . . but are not classed as chemical agents

under any existing protocol.”87 Those would be something other

than nano-sized chemical agents. Most likely, to have any chance

to avoid the CWC88 they would have to be nanobots. While some

“Liposomes, which are first generation nanoscale devices, are being used as drug

88. It is not unreasonable to expect that if nanomimics were actually fielded as

weapons, the user’s chief concern would be their effectiveness as a weapon capable of

defeating existing detection and protection systems, rather than on their actual legality.

That issue, in the past, seemed to arise more as a reaction to international criticism. See,

analysis of the legality of new weapons puts at least a new gloss on that process. See

discussion, infra notes 293–94. If nonstate actors engaged in terrorism obtained such

weapons, it is difficult to conceive that a ban in international law would have any positive

effect; the point of terrorism is, after all, to terrorize. As those groups move toward state

status, however, legal implications might have some impact. An interesting contrast and

comparison might be made with the dualistic approaches of the Democratic People’s

Republic of Korea and its fielding of nuclear weapons, on their perceived interests and

resulting acts. See Elisabeth Bumiller, Gates Looks to Tougher Approach on North Korea, N.Y.

TIMES, May 30, 2009, at A8 (describing the international community’s approach to

North Korea’s nuclear testing). An analogy can be drawn here to the movement of

certain Palestinian groups from pure terrorism to mixed or quasi-state actor approaches

between 1967 and the present. See, e.g., Adam Davidson, Hamas: Government or Terrorist

Altmann, on the other hand, list as military risks of nanotechnology both

“superintelligent, virtually invisible devices” and “nanoweapons, artificial viruses, [and]

controlled biological/nerve agents.” ALTMANN, supra note 36, at 5. Much of Altmann’s

work, while interesting, seems highly speculative, even to a layperson. Note the

emphasized qualifiers in the following:

Whereas with MST [microsystems technology], micro-robots of centimeters,

maybe a few millimeters size could be built, NT will likely allow development of

mobile autonomous systems below 1 mm, maybe down to 10 um (this is still 2-3

orders of magnitude above the size range around 100 nm envisioned for nanorobots

and universal molecular assemblers in MNT).

especially in warfare, many science fiction scenarios have become

science fact.92 It is, in this context, worth noting, in its entirety, an

August 2009 report in the Science Times section of the New York

Times:

You can’t build a machine without parts. That’s true for

large machines like engines and pumps, and it’s true for the

tiniest machines, the kind that scientists want to build on the

scale of molecules to do work inside the body. Researchers at

the Dana-Farber Cancer Institute and Harvard University

have taken a step toward creating parts for molecular

machines, out of DNA. In a paper in Science, Hendrick Dietz

. . . Shawn M. Douglas and William H. Shih describe a

programmable technique for twisting and curving DNA into

shapes. Dr. Shih said the method used strands of DNA that

self-assembled into rigid bundles, with the individual double

helixes joined by strong cross-links. Manipulating the base

pairs in the helixes—using more or fewer of them between

cross-links—creates torque that causes the bundles to twist

and bend in a specific direction. The researchers were able

to control the degree of bending, and were even able to

make a bundle bend back on itself. The researchers built

several structures, including a 12-tooth gear and a wire-frame

ball. Dr. Shih said that while it was possible that a future

molecular machine might use parts like these, the work was

meant to demonstrate that “if you want to make a machine,

you are going to need very precise fabrication ability.” The

goal, he added, is to make objects that are far more complex and

eventually build a machine that could, say, deliver a drug to a

precise spot in the body. Dr. Shih likened the work to the

development of integrated circuits, where complexity has

roughly doubled every 18 months for the past 40 years.

“We’re motivated to improve the technology,” he said.93

Shortly before press time for this article, the Wall Street

Journal published an item headlined “Tiny Robots Made of DNA

Can Walk, Pivot, Work with Microscopic Forklifts.” It said, in part:

For the first time, microscopic robots made from DNA

molecules can walk, follow instructions and work together to

assemble simple products on an atomic-scale assembly line,

mimicking the machinery of living cells, two independent

research teams announced Wednesday.

These experimental devices, described in the journal

Nature, are advances in DNA nanotechnology, in which

bioengineers are using the molecules of the genetic code as

nuts, bolts, girders and other building materials, on a scale

measured in billionths of a meter. The effort, which

combines synthetic chemistry, enzymology, structural

nanotechnology and computer science, takes advantage of

the unique physical properties of DNA molecules to

assemble shapes according to predictable chemical rules.

. . .

These new construction projects bring researchers a

step closer to a time when, at least in theory, scientists might

be able to build test-tube factories that churn out selfassembling

computers, rare chemical compounds or

autonomous medical robots able to cruise the human

bloodstream.

. . .

In the first project, a team of scientists led by

biochemist Milan Stojanovic at Columbia built a molecular

robot that moved on its own along a track of chemical

instructions-the DNA equivalent of the punched paper tape

used to control automated machine tools.

Once programmed, the robot required no further

human intervention, the researchers reported. It could turn,

move in a straight line or follow a complex curve and then

stop, all essentially on its own initiative. They documented its

progress with an atomic force microscope as it strode along a

path 100 nanometers long, about 30 times further than

earlier DNA walkers could manage.

"In the future, this could be used as a molecular machine that

could bind to a cell surface, maybe carry a cargo and release

something," said biochemist Hao Yan at the Biodesign

Institute at Arizona State University, one of 12 researchers at

four universities involved in the project.94

The Arms Control Association recognized many of these

potential issues in 2004 and suggested possible legal responses:

Many of the international legal tools to prevent the

development of these weapons are already in place, notably

the [BWC] and the [CWC], which together ban military use

of all of the weapons imagined here. Nevertheless, these may

prove insufficient to prevent proliferation, and we should not

shy away from new international treaties as necessary.

Foremost among the new treaties that should be considered,

or reconsidered, are those that would: add a compliance

regime to the 1972 BWC; make development, possession, or

use of chemical or biological weapons a crime over which

nations may claim universal jurisdiction (like piracy, airline

hijacking, and torture); and impose a single control regime

over the possession and transfer of dangerous pathogens and

toxins. Consideration should also be given to a new

convention that would prohibit the nonconsensual

manipulation of human physiology, to support and extend

the provisions of the CWC, BWC, and international

humanitarian law.95

What the arms control experts seems to have in mind is not the

“gray goo” scenario,96 or bots attacking soldiers of a specific

genetic make-up,97 though both have been discussed by legal

writers. Rather, the concern is that a nanobot that could target

nerve cells or their receptors and block cholinesterase

production through mechanical means is certainly conceivable.98

dispersion in new forms may become available. See RATNER & RATNER, supra note 37, at

101. The Federation of American Scientists’ website does a very good job at

illustrating this distinction:

Perhaps the most important factor in the effectiveness of chemical weapons is

the efficiency of dissemination. . . . The principal method of disseminating

chemical agents has been the use of explosives. These usually have taken the

form of central bursters expelling the agent laterally.Efficiency is not

particularly high [due to] incineration . . . . Particle size will vary, since

explosive dissemination produces a bimodal distribution of liquid droplets of

an uncontrollable size . . . . The efficacy of explosives and pyrotechnics for

dissemination is limited by the flammable nature of some agents. . . .

Aerodynamic dissemination technology allows non-explosive delivery from a

line source. Although this method provides a theoretical capability of

controlling the size of the particle, the altitude of dissemination must be

controlled and the wind direction and velocity known. . . . An important factor

in the effectiveness of chemical weapons is the efficiency of dissemination as it

is tailored to the types of agent. The majority of the most potent of chemical

agents are not very volatile. . . . The agent must be dispersed within the

boundary layer (<200-300 ft above the ground) and yet high enough to allow

effective dispersal of the agent. . . . A more recent attempt to control aerosol

particle size on target has been the use of aerodynamic dissemination and

sprays as line sources. By modification of the rheological properties of the liquid, its

breakup when subjected to aerodynamic stress can theoretically be controlled and an

idealized particle distribution achieved. In practice, the task is more difficult, but it

represents an area where a technological advance could result in major munition

performance improvements. The altitude of dissemination must be controllable

and the wind direction and velocity known for a disseminated liquid of a

predetermined particle size to predictably reach the ground and reliably hit a

target. Thermal dissemination, wherein pyrotechnics are used to aerosolize the

agent[,] has been used particularly to generate fine, inhalable clouds of

incapacitants. Most of the more complex agent molecules, however, are

sensitive to high temperatures and can deteriorate if exposure is too lengthy.

Solids are a notoriously difficult problem for dissemination, since they tend to

agglomerate even when pre-ground to desired sizes. Dispersion considers the

relative placement of the chemical agent munition upon or adjacent to a

target immediately before dissemination so that the material is most efficiently

used. For example, the artillery rockets of the 1950’s and early 1960’s

employed a multitude of submunitions so that a large number of small agent

clouds would form directly on the target with minimal dependence on

2010] NANOTECH AGENTS 887

addition to the different physics and biology inherent in their

small size,102 swarming,103 and emergence104 technologies may

allow precise dosing by terminating targeting once a lethal dose

has been achieved.105

How much of this really is science fiction, one can only

speculate. It is interesting, though, that BBC News reported in

2008 that:

A tiny chemical “brain” which could one day act as a remote

control for swarms of nano-machines has been invented. The

molecular device—just two billionths of a metre across—was

able to control eight [nanomachines] simultaneously in a

test. . . . “If [in the future] you want to remotely operate on a

tumour you might want to send some molecular machines

there,” explained Dr. Anirban Bandyopadhyay of the

International Center for Young Scientists, Tsukuba,

Japan. . . . “But you cannot just put them into the blood and

[expect them] to go to the right place.” Dr. Bandyopadhyay

believes his device may offer a solution. One day you may be

able to guide the nanobots through the body and control

their functions, he said.106

meteorology. Another variation of this is multiple “free” aerial sprays such as

those achieved by the BLU 80/B Bigeye weapon and the multiple launch

rocket system. While somewhat wind dependent, this technique is considerably

more efficient in terms of agent quantities. In World War I, canisters of

chlorine were simply opened to allow the gas to drift across enemy lines.

Although this produced limited results, it is indicative of the simplicity of

potential means of dispersion . . . . There is sufficient open literature

describing the pros and cons of various types of dissemination to dictate the

consideration of all of them by a proliferant.

To answer that question, others need to be answered: What

are the currently applicable treaties, and do they need to be

modified? To understand their reach it is necessary to first begin

with the core treaty which is still binding, and which is

incorporated in all other currently applicable law, the 1925

Geneva Gas Protocol.109 Indeed, to understand where we are

today, we must closely examine the protocol’s history, reaching

back to the 19th century.

II. TREATIES APPLICABLE TO NANOWEAPONS

A. Facially Applicable Treaties

Several treaties are facially applicable to at least some nanorelated

weapons. They include the 1925 Geneva Gas Protocol, as

well as the more recent Biological and Chemical Weapons

Conventions. Because their background and negotiation are

directly relevant to their coverage, this Article deals with those

points in considerable detail.

1. The 1925 Geneva Gas Protocol

The 1925 Geneva Gas Protocol (“1925 Protocol”) was an

important step in global attempts to ban chemical and biological

weapons but it was neither the first, nor the only step.110 In its

Defense Treaty Inspection Readiness Program (“DTIRP”) noted

that:

The fourth preambular paragraph [of the CWC] recognizes

that the Convention reaffirms the principles and objectives

of, and obligations assumed under, the Geneva Protocol of

1925 and [the BWC] . . . . The Geneva Protocol of 1925, read

together with the reservations made to it, amounts to a ban on

the first use of chemical weapons insofar as it relates to the

United States.111

How did that ban on poison gas come into effect, and what

does it cover? The first question is important to understand the

intent of the drafters and signatories; the second is vital since its

terms are incorporated into and reiterated by both the CWC and

the BWC,112 and are unquestionably current and binding

international law.

AND 1907, at 250 (James Brown Scott ed., 3d ed. 1918) [hereinafter “Hague

Asphyxiating Declaration”]. The 1925 Protocol represents the first multilateral treaty

actually coming into effect which, at least in some instances, banned first use of

chemical weapons in armed conflicts. It was only applicable to signatory parties, and was

subject to use of chemical weapons for reprisal, but it proved, as discussed below,

surprisingly effective. Even nonsignatory states, such as the United States (which signed

but did not obtain Senate ratification until 1975), repeatedly declared their intention to

abide by its terms in wartime. See Barton J. Bernstein, Why We Didn’t Use Poison Gas in

World War II, AM. HERITAGE, Aug./Sept. 1985,. at 40 (“During World War II,

international law did not actually bar the United States from using gas warfare—

although America had signed the 1925 Geneva. Protocol outlawing gas, the Senate had

never ratified it. Yet every peacetime President from Warren G. Harding to Franklin D.

Roosevelt had defined gas as immoral and pledged to abide by the agreement.”).

It is not often that legal analysis can legitimately coalesce

with picture and poem, but I can think of no better way to give

the general public and the average veteran viewed gas warfare in

the decade after the end of the Great War. The work reproduced

(describing the noise that Allied forces associated with the detonation of gas shells as a

distinctive “plop”). The poem reads in full:

Bent double, like old beggars under sacks,

Knock-kneed, coughing like hags, we cursed through sludge,

Till on the haunting flares we turned our backs

And towards our distant rest began to trudge.

Men marched asleep. Many had lost their boots

But limped on, blood-shod. All went lame; all blind;

Drunk with fatigue; deaf even to the hoots

Of tired, outstripped Five-Nines that dropped behind.

Gas! Gas! Quick, boys!—An ecstasy of fumbling,

Fitting the clumsy helmets just in time;

But someone still was yelling out and stumbling,

And flound’ring like a man in fire or lime . . .

Dim, through the misty panes and thick green light,

As under a green sea, I saw him drowning.

In all my dreams, before my helpless sight,

He plunges at me, guttering, choking, drowning.

If in some smothering dreams you too could pace

which directly affected international policy after November 11,

Of vile, incurable sores on innocent tongues,—

To children ardent for some desperate glory,

illustrations of gas warfare in photographs and some deeply

moving paintings. Gas was looked on as something particularly

wicked, something unfair and cowardly, against which a ‘fair

Certainly, gas proponents knew that intense distaste was a

threat to their future. The Chemical Warfare Service of the

many famous authors, and it led directly to the campaigns for the control of

what the French called “armes desloyales” for which the nearest translation is

“unfair weapons”. The argument even had its technical side: many infantry

and artillery officers were baffled by poison gas . . . . Finally, we need to bear in

mind that until 1918 the British and the French were more affected by gas

than the Germans. . . . [I]n the course of 1918 the situation altered. . . . [I]n

Brigadier General Amos Fries, the chief of what was then the

Army’s Chemical Warfare Service, argued that:

[Gas] is far from being the most horrible form of warfare,

provided both sides are prepared defensively and offensively.

Medical records show that out of every 100 Americans

gassed, less than two died, and as far as records of four years

show, very few are permanently injured. . . . Various forms of

gas . . . make life miserable or vision impossible to those

without a mask. Yet they do not kill.120

Fries’ chapter on “The Future of Chemical Warfare” is telling,

both for what it says and for the defensive language it uses about

critics of gas as a legitimate weapon:

The pioneer, no matter what the line of endeavor,

encounters difficulties caused by his fellow-men just in

expanded on that position in his testimony before the United States Senate:

I consider [gas] one of the most important agents in any possible future war. It

caused, even in the last war, when the Germans never fully realized the power

of it until it was too late, and the enemy was never able to produce all he

wanted—it caused over 27 per cent of all the American casualties, although

the death rate was very light from gas. If you take out the deaths from other

causes, the percentage of wounded rises to almost one third of all our

wounded.

67th Cong. 387 (1921) (statement of Amos Fries, Brigadier General). Robert Harris and

Jeremy Paxman would respond later:

[A]dvocates of chemical warfare later argued that gas was actually the most

humane of the weapons used in the First World War, wounding far more than it

killed. But the figures do not reveal either the horror or the persistence of gas

wounds. Nor do they show the psychological casualties. As the fighting

dragged on, the constant state of gas readiness imperceptibly sapped men’s

strength and fighting spirit.

ROBERT HARRIS & JEREMY PAXMAN, A HIGHER FORM OF KILLING 18 (2002).

[T]here appears to have been a deliberate campaign to underestimate the

number of men killed and wounded by gas. Officially, 180,193 British soldiers

were gassed, of whom just 6,062 were killed. However, the list of categories

these numbers do not include is staggering. . . . Apologists for gas warfare used

the statistics to argue that gas was “humane” . . . . And what of the victims of

these “civilized” weapons? In Britain in 1920, 19,000 men were drawing

disability pensions as a result of war gassing. . . . In 1929 Porton [Down

Research Station] investigated a further seventy-two cases of mustard gassing

and found evidence of fibrosis, TB, persistent laryngitis, TB of the spine,

anemia, aphonia, conjunctivitis and pulmonary fibrosis. These, of course, were

secret reports, only declassified years later. In public, Porton maintained that

the popular press “scare-mongered” about the long term effects of gas

poisoning.

proportion as the thing pioneered promises results. . . . [If]

the results promises to be great, and especially if the rewards

promised to the investor and those working with him

promises to be considerable, the difficulties thrown in the

way of the venture become greater and greater. Indeed,

whenever great results are promised, envy is engendered in

those in other lines whose importance may be diminished or

who are so short-sighted as to be always opposed to

progress.121

Fries’ anger at what he clearly considered the ignorance and

illogic of those who oppose gas warfare come through at the

conclusion of his book:

[W]hat should . . . any highly civilized country consider

giving up chemical warfare. To say that its use against savages

is not a fair method of fighting, because the savages are not

equipped with it, is arrant nonsense. No nation considers

such things today. If they had, our American troops, when

fighting the Moros in the Philippine Islands, would have had

to wear the breechclout and use only swords and spears.

Notwithstanding the opposition of certain people who,

through ignorance or for other reasons, have fought it,

chemical warfare has come to stay . . . . It is just as sportsmanlike

to fight with chemical warfare as it is to fight with

machine guns. . . The American is a pure sportsman and asks

odds of no man. He does ask, though, that he be given a

square deal. He is unwilling to agree not to use a powerful

weapon of war when he knows that an outlaw nation would

use it against him . . . . How much better it is to say to the

world that we are going to use chemical warfare to the

greatest extent possible in any future struggle.122

Fries, as it turns out was incorrect in his expectations,123 but

for a very long time his arguments carried a great deal of

weight.124 What they demonstrate here is the other side of a long

and bitter conflict about the morality of using poison gas in war.

b. Efforts to Regulate Poisons and Gases Before World War I

There had, in fact, been considerable discussion of

poisonous and asphyxiating gases before their wide use began in

1915. Part of the reason was the recognition of the illegality of

poisonous weapons articulated in U.S. Army General Order 100

in 1863.125 Another was the philosophy articulated by Czar

Nicholas II of Russia in his proposition for what became the

Hague Conference of 1899: “Hundreds of millions are devoted

to acquiring terrible engines of destruction, which, though today

regarded as the last word of science, are destined tomorrow to

􀀃

In defiance of facts, experience and history, the nations of the world are still

striving to outlaw chemical warfare. This is due in part to blind ignorance, lack

of imagination, and, in no small degree, to misinformation. It may seem

incredible but we have a situation in this country where the American Legion,

a group of men who have fought in the last war and many of whom would fight

in the next one should another come, favor chemical warfare as over against

other weapons while the President and his administration are opposed to its

use and are attempting to outlaw it.

Id. at 60. He adds that:

[A]nti-gas sentiment as embodied in the [1925 Geneva Gas Protocol] but the

only logical conclusion that can be drawn is that it was insincere. The delegates

had their ears to the ground and followed the popular clamor of the moment,

disregarding history, the established practice, and the admitted facts regarding

the efficiency and humanity of chemical warfare. Such has always been the

course of these so-called world conferences. They proclaim some . . . scheme

. . . only to be soon forgotten or disregarded.

Id. at 73. He concludes:

Owing to the primordial aversion to the new, combined with prejudice,

propaganda, and the desire of statesmen and diplomats for popular acclaim, it

has been easy in peace time to secure conventions of this nature. But when

whole populations become fanned into a passion and war in all its grim and

sordid reality comes, “military necessity” will compel the contending parties to

employ the most efficient weapons at their disposal.

field.”126

Choate discusses the gas provision of the First Conference:

“In the same spirit of humanity, the Conference of 1899, after

much discussion, agreed to abstain from the use of projectiles,

the object of which is the diffusion of asphyxiating of deleterious

gases . . . .”127 In fact, in 1899 it was the Russian delegate who

introduced the asphyxiating gases proposal, and who, when

others objected that all explosives produced gases which might

asphyxiate, defined the prohibition to “include only those

projectiles whose object is to diffuse asphyxiating gases, and not

to those whose explosion produces incidentally such gases.”128

Choate then discusses the prohibition, at the 1907 Conference,

of the launching of projectiles from balloons, which he says was

embodied in the comment of a British delegate who asked what

purpose would “be served by the protective measures already

adopted for war on land, if we open to the scourge of war a new

field more terrible perhaps than all the others?”129

The second Hague reiteration of the 1899 ban on poison

weapons,130 and the continuation of the 1899 limits on

asphyxiating gases seemed quite clear, and yet eight years after

the 1907 Convention, Germany deployed chlorine gas at Ypres,

impact did the use of gas and its rationale at the time have on

Post-World War I treaty making?

c. What Happened in the Great War?

At the very core of the legal dispute involving German use of

gas in 1915 were drafting ambiguities in the pertinent treaties:

Did “asphyxiating” cover gases which worked through other

means such as skin absorption? Did “poison” cover nonlethal or

allegedly nonlethal weapons? Was release of gas from cylinders

within the coverage of the ban on “projectiles?” Were fine

powders considered as gases if they had the same effect?

Germany’s arguments were widely discussed both during,

and immediately after the war. Germany took the position that

France had made “prior use of asphyxiating gases.”132 It cited

instructions issued by the French Ministry of War on February 21,

1915 concerning grenades and gas cartridges containing

“stupefying gases,” the purpose of which was to “make untenable

the surroundings of the place where they burst.”133 The

instructions provided that “the vapors [of the] asphyxiating gases

are not deadly, at least when small quantities are used.”134 The

Germans took the position that, of necessity, the French were

admitting the gases were deadly in large quantities, and that they

were simply reprising with their later attacks.135

Ludwig F. Haber, the son of the man who was held

responsible for Germany’s use of chlorine gas in 1915,136 has

published an extensive study of the subject:

The spirit of the Conventions was surely clear enough: to

stop new and potentially more awful weapons. But the letter

was obscure and open to widely differing interpretations . . . .

When the Germans used gas at Ypres, they were held to be in

breach of the Conventions on several counts . . . [Germany]

argued at the time, and later, that (i) the Conventions did

not cover gas blown from cylinders, (ii) the Allies had used

gas first, (iii) gases were not poisonous, and (iv) after the

war, gas shells were implicitly excluded because they were

not causing needless suffering . . . . [Haber seems to

conclude the German claims of Allied first use are

questionable at best]. The most one can say about gas and

smoke is that by the eve of the war military awareness of

chemical had increased to the extent that some soldiers were

willing to consider them and a very few, with a more

innovating turn of mind, were even experimenting with

various compounds. The substances used with the exception

of phosgene, were not toxic. There were no military stocks of

gases, nor of gas shell, save for very limited supplies tear gas

grenades and cartridges in French hands.137

The military reaction was mixed on both sides. The German

commander of the Army Corps at Ypres said in his memoires:

I must confess that the commission for poisoning the enemy,

just as one poisons rats, struck me as it must any

straightforward soldier; it was repulsive to me. If, however,

the poison gas were to result in the fall of Ypres, we would

win a victory that might decide the entire campaign. In view

of this worthy goal, all personal reservations had to be

silent . . . . War is necessity and knows no exception.138

It is important here to note that many of the weapons used by

both sides were not gases per se. Rather, they often involved

particles of toxic materials disbursed in smokes and or by shell

fragmentation.139 Thus, Haber points out:

[T]he particular anxiety caused by the German Blue Cross

shells [was] with their arsenical filling. Whilst the German

139. As the Military Law Review points out:

The gas shell used in 1915 . . . evolved from an earlier model which was first

used in October 1914. At that time double salts of dionialine was added to the

powder of the projectile. The irritant would hover as dust in the air after the shell

burst. It was not very intense. Nevertheless, an unnoticed important first step

had been taken toward gas warfare.

SBR140 were produced . . . . Blue Cross shells were a potential

danger, and the Allied experts were concerned that the Germans

might introduce arsenical smoke generators; soldiers would

thereby be rendered so debilitated that they couldn’t fight

any more.141

Finally, Haber again raises the issue of the Hague conventions:

The agreements were negotiated and signed at a time when

statesmen were supposed to have moral standards, and it was

generally expected that such declarations of principles . . .

would be respected by all belligerents in a future war. The

events of August-September 1914 [German’s invasion of

Belgium] dented these illusions, the German [use] of

chlorine the following spring shattered them, and set a

precedent [contemporary language] still conveys the

emotional shock. Conan Doyle wrote that the Germans had

“sold their souls as soldiers” . . . it was only a short step to

legitimize the use of gas at all times, and not solely in

retaliation against the enemy’s first use. . . . The German

post-war attitude was that the Hague Conventions still

applied, indeed they had not been breached in 1915–18.

[Furthermore] in any case the Germans had not been guilty

of a precedent for it was the French who had first used

bullets and shells with toxic materials.142

Haber concludes that the practical effect of these attitudes

was that international agreements to abandon poison gas would

be meaningless unless accompanied by peacetime verification

and wartime sanctions against transgressors.143 The Allies, as

victors, and eventually as treaty negotiators, seemed to disagree

with that conclusion, for in the postbellum period they produced

a number of treaties designed to prevent future uses of

poisonous and asphyxiating gases and similar “processes” or

“devices.”144 What they meant by those words is a key to analysis

in this Article.

asphyxiating gases, and that they specifically knew and predicted that additional new

d. Post-War Efforts to Control Chemical Warfare

The fear of chemical war in general, while initially pointed

at Germany, was, in fact, by the end of the decade, directed

generally at all industrialized powers. In 1928, a French author

predicted that:

Everyone foresees this new form of plague will rapidly

progress. No one doubts that if war explodes again each side

will use chemical weapons which will play the central role;

everything else will be an accessory. These weapons, studied

in secret and prepared in the world’s laboratories, will

become progressively more deadly.145

Bernauer summarizes the post-war situation:

Increasing public awareness of the horrors of chemical

warfare stimulated further efforts aimed at a ban on

[chemical weapons]. The Treaty of Versailles prohibited

Germany, the State which had used chemical weapons first in

World War I, from manufacturing or importing poisonous

gases. Other peace treaties of 1919-20 contained similar

provisions. The Treaty of Washington which was to limit the

use of submarines, but never entered into force, included

limitations on the use of noxious gases . . . . In May, 1925, a

conference on methods to control the international arms

trade was convened in Geneva within the framework of the

League of Nations. At this conference the United States

initially proposed a prohibition of the export of chemical

weapons. Many states objected to such a ban . . . . The

United States therefore proposed to conclude an agreement

banning the use of chemical weapons in war.146 As a result of

a Polish initiative, biological means of warfare were added.

On 17 June 1925 the “Protocol for the Prohibition of the

Use in War of Asphyxiating, Poisonous or Other Gases, and

of Bacteriological Methods of Warfare” was adopted. It was,

146. The use of the word “therefore” may not be entirely accurate. As discussed

infra in Part II.A.1.d.iii, the reasons for the U.S. proposal of a ban on use of chemical

weapons seemed to lie in domestic politics rather than within the conference

negotiations.

by and large, modeled after Article 5 of the Washington

Treaty of 1922.147

The initial steps to reach that protocol began, as Bernauer

notes, with the drafting in 1919 of the Treaty of Versailles148

which ended the war between Germany and the Allies, and

continued with the other separate treaties ending the war with

other members of the Central Powers.149

i. The Treaties Ending the War

The language most often cited as a starting point for the

post-World War I legal treatment of chemical weapons is article

171 of the Treaty of Versailles: “The use of asphyxiating,

poisonous or other gases and all analogous liquids, materials or

devices being prohibited, their manufacture and importation are

strictly forbidden in Germany. The same applies to materials

specially intended for the manufacture, storage and use of the

said products or devices.”150 The French version of article 171

reads: “L’emploi de gaz asphyxiants, toxiques ou similaires, ainsi que de

tous les liquides, matieres ou procedes analogues etaient prohibes, la

fabrication et l’importation en sont rigoureusement interdites en

Allemagne. Il en est de meme du materiel specialement destine a la

fabrication, a la conservation ou a l’usage desdits produits ou

procedes.”151

The broad language of the Allied drafters at Versailles was

not unintentional. Among the “main principles which guided the

Allies in framing the Military Terms” of the Treaty was to “avoid

all ambiguity, which might hereafter give Germany a pretext for

evading her obligations.”152 Verwey points out that, in fact, the

original text in article 5 of the pre-Versailles draft, “Concerning a

use of asphyxiating, poisonous or similar gases, any liquid, any

material and any similar device capable of use in war are

forbidden.”153 “There is no doubt,” says Verwey, “that this

formulation was intended to mean ‘forbidden in and to

Germany’,154 since the Allied Powers certainly did not intend to

give up the production of chemical weapons themselves.”155

Later, he notes, the provision shows up as article 13 of the

“Naval, Military and Air Conditions of Peace” where the

Versailles article 171 language appeared.156 Verwey says that

“[t]here is no indication . . . in the records that the phrase ‘being

prohibited’ was inserted on purpose,” and that the discussions

rather point to the opposite conclusion; that the entire article

was related to Germany’s obligations alone . . . .”157 Verwey’s

conclusion that the gas articles of Versailles and other treaties

were aimed at the Central Powers alone seems to be the correct

interpretation,158 although its significance was, for present

154. In their official response to protests of the treaty’s harshness from the German

delegation at Versailles, the Allies stated that Germany was “the first to use poisonous

gas notwithstanding the appalling suffering it entailed” and that, inter alia, was “why

Germany must submit for a few years to certain special disabilities and arrangements.”

them in a state of permanent military inferiority. Wilson’s fourth point called

for the reduction of national armaments ‘to the lowest point consistent with

domestic safety,’ but it was applied only to Germany.

157. Id. Verwey adds that this impression is supported by the insertion of

flamethrowers into the concomitant articles of the peace treaties with Austria (article

135) and Hungry (article 119), noting “[i]t could hardly be [argued] that anno in 1919

flamethrowers were considered prohibited by specific customary international law.” Id.

1925, when the later treaties incorporated and ratified the

relevant language.159

What is important for this Article, however, is the Versailles

ban on devices,160 which was, indeed, present in the drafts from

the very beginning.161 It is interesting to note that the various

treaties ending the war with the Central Powers were not exactly

the same regarding banned chemical weapons. As noted above,

article 171 of Versailles refers to “analogous liquids, materials or

devices.”162 The Treaty of St. Germaine-en-Laye,163 which ended

159. The conclusion seems logical, since everything in the drafting process of the

post-war treaties was designed to prevent the losing parties from ever again presenting a

military threat. See BROWN, supra note 119, at 52. He notes that:

There was . . . a significant difference between the first draft prepared by the

Foch Committee of the Supreme War Council on March 3, 1919, and the final

article. The draft article was blunt . . . .

“Production or use of asphyxiating, poisonous or similar gases, any liquid,

any material and any similar device capable of use in war are forbidden.”

The draft article was accepted without comment on March 6 and March 10,

1919. The regulations were redrafted to reflect substantive comments on other

articles between March 10 and March 17. In the redrafted regulations . . .

Article 5 became Article 13, and the wording was changed to that of the final

Article 171. There is no indication that the change in wording was realized to be other

than procedural.

Id. at 52–53 n.1. (emphasis added) (citations omitted); see also A HISTORY OF THE PEACE

CONFERENCE OF PARIS, supra note 152, at 134 (“Whatever we may do to reduce the

strength of the German Army, and to prevent the military training of the people, there

are, and will for some time continue to be, in Germany several millions of men trained

with ample war experience. These are accomplished facts, which we are powerless to

alter. On the other hand, it is quite possible to deprive Germany of the arms, ammunition, and

the reference to devices: “The use of flamethrowers,

materials or devices being prohibited . . . .”165 Apparently, there

“devices” still modifies “gases” since the language is unchanged

from Versailles except for the addition of flamethrowers.166

There has been considerable discussion about the meaning

of the word “similares” modifying asphyxiating and toxic gases in

the French version, versus the word “analogous” in the English

text.167 During the Vietnam conflict, the United States took the

Conventional Weapons language, makes it clear that states have not viewed that weapon

as a “device” covered by the 1925 Protocol or subsequent treaties.

165. Treaty of St. Germaine-en-Laye, supra note 163, art. 135.

166. Immediately before presentation of the draft Treaty of Versailles to Germany

on May 10, 1919, the Council of Four (Lloyd George of England, Vittorio Emanuele

Orlando of Italy, Georges Clemenceau of France, and Woodrow Wilson of the United

States) decided to next complete the treaty with Austria-Hungary and ordered its

Central Secretariat to prepare a draft. 4 A HISTORY OF THE PEACE CONFERENCE OF PARIS:

THE SETTLEMENT WITH GERMANY 141–42 (H. Temperley ed., 1920). The military clauses

were drafted by the British section which followed the general arm limitations imposed

on Germany. Id. at 143. The council’s military representatives adopted the British draft,

which followed the Versailles language precisely “except that the word Flammenwerfer

[flamethrowers] was added in the first line of Article 135.” Id. at 150. Thus, the

modification of “gases” by “devices” not only preceded the additional word, there was

apparently no intent to do anything other than add another banned weapon to a

convenient clause.

167. A General Conference for the Reduction and Limitation of Armaments under

the sponsorship of the League of Nations and attended by League members plus the

United States and the Union of Soviet Socialist Republics (“U.S.S.R.”) took place in

Geneva from 1932 to 1934. See Mount Holyoke College, Department of International

Relations, Disarmament Discussions 1932-34, http://www.mtholyoke.edu/acad/intrel/

WorldWar2/disarm.htm (last visited Apr. 3, 2010). In the preparatory work for that

2010] NANOTECH AGENTS 905

position that the French text excluded tear gases because they

were not similar to choking or poisonous gases and others

disagreed because they thought tear gas “analogous.”168

There has not, however, been a similar discussion of

whether there is a distinction between “analogous devices” and

procedes analogues,” in the second clause of the first sentence of

article 171.169 The word “devices” in the specific sense of related

equipment or application is better articulated with “appareil

(apparatus) or “dispositif” (device).170 While “procede” may be

translated as “processes” in general circumstances, for example

technique de fabrication (manufacturing technique), it also carries

a more specific meaning.171 Procede” has the strong connotation

of bringing about a similar result or end-state. One common

synonym for “procede” appears to be “conduite” (behavior).172

Indeed, a subtext of artificially obtaining an analogous result is

inherent in the word. It is therefore significant that the

􀀃

conference, the British Foreign Office produced a Memorandum on Chemical Warfare

which pointed out “a serious ambiguity” regarding the translation of the word

“similaires” as “other.” See Minutes of the Sixth Session (Second Part) of the Preparatory

Commission for the Disarmament Conference, Minutes of Twentieth Meeting, December 2, 1930,

League of Nations Series No. 9, 311 (1931), available at

http://digital.library.northwestern.edu/league/le00307h.pdf. The U.K. memorandum

proposed French and English language drafts which substituted the English word

“similar” for “other.” Id. More interesting here, the U.K. draft also substituted, without

comment, the word “processes” for “devices” as a translation for “procedes.” Id. The

conference adopted the U.K. draft, but, of course, it never produced even a final draft

treaty before it dissolved in light of events which were to lead to the Second World War.

translation “processes” was used elsewhere,173 but rejected for

“devices.” Thus, the French version provides some additional

evidence that the intention was to include entities with similar or

analogous effects, outcomes, or behaviors, rather than simply

devices associated with distribution of otherwise banned

substances.174

The situation, of course, gets more complicated. In the

Treaty of Neuilly-sur-Seine with Bulgaria, flamethrowers are kept

in the relevant article 82, but the word “processes” is substituted

for “devices.”175 Does that substitution indicate any intent to

change the nature of the treaty? It is difficult to support that

conclusion, because six months later when a treaty is signed with

Hungary, the language veers back to “similar devices.”176 Later in

1920, the preliminary treaty with Turkey again contained the

“similar processes” phrase,177 but, to complicate the puzzle even

173. See infra notes 175, 177 and accompanying text (using “processes” in other

treaties ending World War I).

174. Interestingly, Josef Kunz, in Gaskrieg und Volkerrecht, says:

Durch Versailles, Artikel 171, wird Deutschland die Herstellung und Einfuhr von

171, Germany is strictly forbidden from the production and importation of

suffocating, poisonous and similar gases, of all corresponding liquids,

mentioned as well as by all material particularly intended for the production,

storage or the use of the products or kinds of procedure mentioned.]

JOSEF KUNZ, GASKRIEG UND VOLKERRECHT 37 (1927) (authors translation). Kunz uses

the phrase “entsprechenden . . . Verfahrensarten” (corresponding type of procedure)

which effectively translates the French phrase “procedes analogues,” but which in the

context must mean something else, since as used, a “type of procedure” could not in

itself be produced, stored, or imported. Id. It is telling that in the next sentence, he

concludes that article 171 is “identisch sind” (identical with) the parallel articles of the

other treaties ending World War I. Id.

further, the entire article relating to chemical weapons was

deleted when the final version of the treaty was signed in 1923.178

In short, every treaty except Versailles bans flamethrowers,

and every treaty except Versailles uses the word “similar” while

Versailles utilizes “analogous.” However, the first, second, and

fourth treaties use “devices” while the operable word in the third

and fifth is “processes.” How is it possible to know what the

language was intended to mean? Interestingly, article 172 of the

Treaty of Versailles required that Germany “disclose . . . the

nature and mode of manufacture of all explosives, toxic

substances or other like chemical preparations used by them in the

war or prepared by them for the purpose of being so

used . . . .”179 By contrast, it did not require the disclosure of

similar or analogous devices or processes.180 Whether or not it is

even possible to deduce from this dissimilar language that the

drafters had any particular intent, it is at least clear that they were

aware that language could vary in many ways, and seemed to

choose the broadest possible language in the ban contained in

article 171 and its parallels in other treaties.181

Fries’ discussion of methodology current in 1921 is

enlightening:

[W]e must expect that new gases, new methods of turning

them loose, and new tactical uses will be developed . . . .

Some of the poisonous gases are so powerful in minute

quantities and evaporate so slowly that their liberation does

not . . . cause a cloud. Consequently, we have gases that

cannot be seen. Others form clouds by themselves, such, for

instance, as the toxic smoke candle, where the solid is driven

off by heating . . . . It would be idle to attempt to enumerate

the ways and means by which chemicals will be used in the

future. In fact, one could hardly conceive of a situation

where gas or smoke will not be employed, for these materials

may be liquids or solids that either automatically, upon exposure to

the air, turn into gas, or which are pulverized by high explosive, or

driven off by heat. This varied character of the materials

enables them to be used in every sort of artillery shell, bomb

or other container carried to the field of battle.182

It is worth noting that Fries’ arguments about the technical

legality of German conduct were still being made as late as 1942,

when a law review note was published stating that “[b]rutal as she

otherwise was, Germany did not violate international law by the use of

chlorine on April 22, 1915.”183 Of course, the thesis of that note is

somewhat impacted by its concluding sentence: “There is hardly

a field of peaceful human endeavor which does not owe a debt to

the Chemical Warfare Service.”184 Of particular interest here,

though, is the author’s argument that:

The Germans had [in 1914] developed a [lacriminatory] gasfilled

artillery shell by modifying a 10.5 cm. shrapnel . . . .

This gas projectile was not within the interdiction of

Declaration II [of the Hague Convention], for diffusion of

asphyxiating or deleterious gas was not its sole object. Its

main purpose was that of shrapnel against personnel.

Further, it disbursed a fine dust of solid and not a gas.185

Indeed, as Fries points out, one of the areas where Germany did

early work was in arsenic derivatives.186 The most commonly used

German arsenical was diphenylchloroarsine (“Blue Cross”),

which was “a white solid, which readily penetrated the [gas mask]

canister and caused sneezing.”187 This substance

was used in shells carrying a high bursting charge. The

explosion of the shell scattered the Sneezing Gas in the form

of a very fine cloud of particles. While the charcoal of the

mask will remove most poisonous gases, it has no protective

power against clouds or mists. The Sneezing Gas passed

through the best canister, and through its peculiar

physiological effect caused great discomfort to the men and

professional soldiers and diplomats knew very well at the end of

World War I that poisonous, asphyxiating, and related weapons

came in forms other than gas;190 signatory states might be

Cross shell and quickly realized its ability to penetrate their respirator. Inspired by those

Blue Cross experiments, they “perfected the thermogenerator . . . which produced an

as causing intense pain in the sinuses it also created temporary but intense feelings of

psychological misery.” JONES, supra note 187, at 57–59. Thermogenerator grenades,

also recognized that there was a distinction between irritant gas candles and toxic smoke

910 FORDHAM INTERNATIONAL LAW JOURNAL [Vol. 33:858

One startlingly applicable statement regarding such

weapons was made by ex-Major Victor Lefebure, who had served

from November 1917 through the end of the war as the British

liaison officer with the French Army for chemical warfare.193

Lefebure later authored The Riddle of the Rhine about the German

chemical industry and its ties to gas warfare.194 In 1921 he was

invited to address the Grotius Society as part of its Problems of

Peace and War series.195 Lefebure began his address by arguing

that “chemical warfare is far too potent, decisive, flexible, secret,

and generally dangerous to be left unharnessed in a world which

pretends to disarm.”196 He devoted much of his address to how

new chemical weapons are developed through research,

development and manufacturing stages, and he proposed

designing applicable treaty controls at all three stages.197 His

conclusion, however, not only resonates after almost ninety years,

but it is direct evidence of how broadly weapons-related scientists

and soldiers were thinking contemporaneously with the drafting

of the treaties discussed here:

I should point out that these remarks are not limited to

chemical warfare, but they apply to the development of all

new weapons. Taking a long-distance view, no distinction should

be made. If sub-atomic forces can eventually be harnessed for war

they must be subjected to the same control and attempts at

suppression during their development stages. Chemical warfare

happens to be the present problem of the maximum

practical importance in this field.198

committee notes:

The term “gas” as used in connection with warfare does not correspond to the

scientific definition of gases. In reality it includes not only gases but solid or

liquid substances which are reduced to powder or spray in the air . . . . Such

Thus it seems clear from the evidence that the Versailles

Treaty drafters knew the poisonous and asphyxiating “gases” of

the Great War were often something other than gas in the

technical sense of physicists,199 and that there was an attempt at

inclusion rather than exclusion of anything which might produce

analogous results. It does not assist the researcher attempting to

divine intent that many of the negotiations were kept secret and

the records ostensibly destroyed.200 Once again, however, there is

some other guidance. In a 1922 analysis of the “Secret Minutes of

the Paris Peace Conference” the New York Times revealed that:

Two things were at once assumed by the conference and

brushed aside, as the most vital problems often are,

practically without discussion: First, that Germany should be

utterly disarmed, so far as military uses were concerned, of

airplanes, poison gas, submarines, tanks, etc. Every one [sic]

agreed to that. Second, no one at Paris considered for a

moment an immediate general reduction of armament in

these new Instrumentalities which should apply to the allies

as well as to the enemy States . . . . They were all agreed on

an absolute prohibition of the military use of gases . . . . But

ordinarily manufactured and employed in large quantities for peace-time

requirements, so that “there is very little difference between the manufacture of

pharmaceutical products and that of injurious substances used in war.”

molecules are practically unrestricted by intermolecular forces so that the molecules are

describe a finely divided solid of organic or inorganic matter”). ASTM International,

originally known as the American Society for Testing and Materials, is a voluntary

standards development organization and source for technical standards. See About

ASTM International, http://www.astm.org/ABOUT/aboutASTM.html (last visited Apr.

from incomplete combustion.” Id. at 433. That understanding of the meaning of

“smoke” really has not changed since W.F.M. Goss noted in 1916, that the properties of

smoke were defined as “gaseous and solid products of combustion, visible and invisible,”

and that smoke regarded as possessing both solid and gaseous constituents. W.F.M.

the other Allies wished to go much further. They wished to

compel the German Government to disclose her chemical

processes and secrets . . . . [Secretary of State Robert Lansing

expressed President Wilson’s view that] “since the use of

asphyxiating, poisonous or other gases and all analogous matters or

devices had been prohibited,201 including their manufacture or

importation, he thought that was sufficient safeguard . . . .” It

became crystal clear as these discussions developed that everything

depended upon point of view . . . . If men looked upon inventions

were not enough [Wilson argued, what was needed also was a

In any case, it was the “analogous devices” language of

Versailles that was adopted first by the Washington Naval

Conference in 1922,203 and then in the 1925 Geneva Gas

Protocol.204 The history behind these words indicates, however,

that the drafters specifically chose “analogous devices” over

“similar processes,” that they were determined to prevent

Germany from again arguing that such weapons were outside the

scope of treaty language, and that they were very well aware that

suppressing poison gas was unwise and unworkable,210 and issued

a public report on January 6, 1922, which concluded that “the

the end that this prohibition shall be universally accepted as

to such a prohibition . . . .216

Note that the emphasized language differs significantly from the

Versailles treaty.217 Apparently, there was a scrivener’s error in

the copying of Versailles article 171, or Root erred in its reading.

By the time the treaty was signed, however, article 5 of the

Washington Submarine Treaty was again congruent with

Versailles. It provides:

The use in war of asphyxiating, poisonous or other gases,

and all analogous liquids, materials or devices, having been

justly condemned by the general opinion of the civilized

world and a prohibition of such use having been declared in

treaties to which a majority of the civilized Powers are

thereto.218

iii. The 1925 Geneva Gas Protocol

The Geneva Protocol of 1925 placed the 1922 Washington

use ban on the table for all states.220 The U.S. Senate, however,

after the country acted as the prime proponent of a ban, refused

to ratify the protocol at that time.221

Once again, the 1925 protocol articulated an attempt to ban

use in war of chemical weapons, and once again the “devices

versus processes”222 question arises. The language of the protocol

tracks the 1922 treaty:

219. Chemical Weapons Convention, supra note 10, pmbl.

and the 1925 protocol were drafted in light of a wide effort to end all international

armed conflict. See generally JAMES SHOTWELL, PLANS AND PROTOCOLS TO END WAR,

221. See HARRIS & PAXMAN, supra 120, at 47–48 (“The United States Chemical

Warfare Service launched a highly effective lobby . . . . As has often happened since, the

fight for chemical weapons was represented as a fight for general military preparedness.

Senators joined the CWS campaign, among them the chairman of the Committee on

Military Affairs who opened his attack on ratification in the senate debate with a

reference to the 1922 Washington Treaty: ‘I think it is fair to say that in 1922 there was

much of hysteria and much of misinformation concerning chemical warfare.’”). As

noted earlier, the United States eventually ratified the 1925 Geneva Gas Protocol in

1975, supra note 22, and its binding nature was, of course, reiterated in the CWC.

Chemical Weapons Conventions, supra note 10, pmbl. It is interesting to note that prior

to ratification, the acting director of the U.S. Arms Control and Disarmament Agency

testified to the U.S. Senate that:

This is an area in which a fairly substantial amount of research has now begun

to be undertaken and hopefully on the basis of that we would be able to

approach this problem on the basis of the 1967 study and not on the basis of a

1925 convention, no disrespect intended to the drafters of the 1925 convention, they

did the best they could with the information available at their disposal, but the total

activity should be looking at the problem of a new situation rather than the

same amount of energy expended on the question of whether or not we

should ratify the 1925 convention.

Disarmament of the Comm. on Foreign Relations, 90th Cong. 180 (1967) [hereinafter 1967 S.

Hearings on Arms] (testimony of Sen. Adrian S. Fisher) (emphasis added).

222. As noted above, variations in the language of the treaties, and in the two

official text languages of French and English, have in the past been the subject of

considerable international discord. See supra Part II.A.4.a. These problems carried over

into the 1925 protocol. For example, the 1925 Geneva Protocol was long the subject of a

dispute over whether it banned “tear” gasses: The English version of the protocol stated

that “the use in war of asphyxiating, poisonous or other gases” was prohibited, while the

2010] NANOTECH AGENTS 917

Whereas the use in war of asphyxiating, poisonous or other

gases, and of all analogous liquids materials or devices, has

been declared in Treaties to which the majority of Powers of

the world are Parties; and To the end that this prohibition

shall be universally accepted as a part of International Law,

binding alike the conscience and the practice of

nations . . . .223

Similarly, the official French version is, in all operative

language, precisely the same as the 1922 treaty:

Considerant que l’emploi a la guerre de gaz asphyxiants, toxiques

ou similaires, ainsi que de tous liquides, matieres ou procedes

analogues, a ete a juste titre condamne par l’opinion generale du

monde civilise, CONSIDERANT que l’interdiction de cet emploi a

Puissances du monde, DANS LE DESSEIN de faire universellement

reconnaitre comme incorporee au droit international cette

interdiction, qui s’impose egalement a la conscience et a la pratique

des nations . . . .224

􀀃

French version referred to “l’emploi a la Guerra de gaz asphyxiants, toxiques ou similares.” See

Geneva Protocol, supra note 23. For the interpretation that the protocol did not ban tear

gas, the United States, which argued for the legality of use of “non-lethal gases” in war,

relied on the word “similares” (similar) in the French version of the protocol, rather

than “autres” which would have been a direct translation of the word “other,” as in the

English version. See VERWEY, supra note 170, at 226–27 (discussing implications arising

from apparently conflicting texts in the French and English versions of the protocol).

The United States took the position that while “other” gases might include tear gases,

they were not “similar” to toxic or asphyxiating gases. See id. at 227; cf. Limitations on Use

The historical and textual analysis above225 is equally

applicable here. There is simply no doubt that the authors had in

mind, given their then current knowledge and environment, a

concern that limiting the treaty to analogous liquids and

materials might miss something that had already been used or

which could be developed, and that the inclusion of “devices”

was no accident. That conclusion is strongly supported by the

French use of the word “procedes” in lieu of alternative

phraseologies.226 As will be seen below, the 1925 protocol has

been incorporated into newer treaties, but it has never ceased to

customary law.227 The protocol did not entirely eliminate use in

war of toxic or asphyxiating chemical weapons, but, as the

following discussion shows, their use was certainly curtailed after

1925.

iv. Practical Effect of the Protocol and Other Post-War Law After

1925

Although chemical stockpiles continued to grow long after

the 1925 protocol entered into effect, their actual use in war was

greatly curtailed.228 While there was some documented use, both

before the protocol, the United Kingdom in Siberia (1919,

arsenicals)229 and the Third Rif War (1924, mustard gas),230 and

recognized the declaratory nature of the 1925 protocol. See 1967 S. Hearings on Chemical

Agents, supra note 222, at 55 (testimony of Cyrus Vance, U.S. Deputy Sec’t of Def.) (“We

afterwards, Italy in Ethiopia (1936, mustard gas)231 and Japan in

China (1937–1945, certainly mustard and biological warfare,

possibly other gases),232 usage was generally limited to attacks by

colonial powers on those with no means of reprisal who were

viewed by the user as engaged in otherwise illegitimate warfare.233

chemical or toxic weapons as late as after World War II,234

Committee of the Red Cross (“ICRC”) documented Italian use of mustard gas in a

report filed by Doctor Marcel Junod of the ICRC delegation to Ethiopia:

Junod also confronted the appalling reality of mustard gas and its effects:

“That evening [18 March 1936] I had occasion to see with my own eyes an

Italian aircraft spraying the ground with an oily liquid, dropping like fine rain

and covering a huge area with thousands of droplets, each of which, when it

touched the tissues, made a small burn, turning a few hours later into a blister.

It was the blistering gas the British call mustard gas. Thousands of soldiers

were affected by severe lesions due to this gas . . . .”

232. According to historians Yoshiaki Yoshimi and Seiya Matsuno, chemical

weapons were authorized by specific orders given by Emperor Shōwa himself,

transmitted by the chief of staff of the army. For example, the emperor authorized the

use of toxic gas on 375 separate occasions during the battle of Wuhan from August to

October of 1938. They were also used during the invasion of Changde. Those orders

were transmitted either by Prince Kotohito Kan’in or General Hajime Sugiyama. See

YELLOW RAIN: A JOURNEY THROUGH THE TERROR OF CHEMICAL WARFARE (1982)

allegedly used mustard and other nerve agents in Yemen against royalist rebels during

the early- and mid-1960s. See TUCKER, supra, note 42, at 190–96 (discussing Egypt’s

alleged use of chemical agents).

235. This is documented by the respected international security analysis group

GlobalSecurity:

In 1982, early in the Iran-Iraq War, the Iraqis used riot control agents to

repel Iranian attacks. They progressed to the use of CW agents in mid-1983

with mustard, and in March 1984 with tabun (the first use ever of a nerve

agent in war). The Iraqis continued to use chemical weapons until the end of

hostilities in August 1988; in addition they introduced the nerve agents sarin

and GF late in the war.

In March 1986, UN Secretary General Javier Perez de Cuellar formally

accused Iraq of using chemical weapons against Iran. Citing the report of four

chemical warfare experts whom the UN had sent to Iran in February and

March 1986, the secretary general called on Baghdad to end its violation of the

1925 Geneva Protocol on the use of chemical weapons. The UN report

concluded that “Iraqi forces have used chemical warfare against Iranian

forces”; the weapons used included both mustard gas and nerve gas. The

report further stated that “the use of chemical weapons appear[ed] to be

more extensive [in 1981] than in 1984.” Iraq attempted to deny using

chemicals, but the evidence, in the form of many badly burned casualties

flown to European hospitals for treatment, was overwhelming. By July 1986 it

was estimated that Iraqi chemical warfare was responsible for about 10,000

casualties.

Although the Iraqis initially used chemical weapons to prevent defeat and

to reduce battlefield losses, they later integrated CW attacks into combinedarmed

operations designed to regain lost territory and to gain the offensive.

Iraq’s use of CW in the war with Iran can be divided into three distinct phases:

1. 1983 to 1986--used in a defensive role; typically to deflect Iranian

human-wave assaults. In 1984 Iraq became the first nation to use a nerve

agent on the battlefield when it deployed Tabun-filled aerial bombs

during the Iran-Iraq war. Some 5,500 Iranians were killed by the nerve

agent between March 1984 and March 1985. Tabun kills within minutes.

Some 16,000 Iranians were reported killed by the toxic blister agent

mustard gas between August 1983 and February 1986.

2. 1986 to early 1988--iraq adapts use against Iran to disrupt Iranian

offensive preparations.

3. early 1988 to conclusion of the war-- Iraq integrated large nerve agent

strikes into its overall offensive during the spring and summer of 1988

leading to the ceasefire.

Iran used chemical weapons late in the war, but never as extensively or

successfully as Iraq. The success of Iraqi offensive operations in the southern

sector in mid-1988 ultimately caused the Iranians to cease hostilities. The use

of chemical weapons contributed to the success of these operations.

2010] NANOTECH AGENTS 921

These attacks are the only general use of mustard gas in

continuous and open conflict since 1918, and the first fully

documented use of nerve gases in war. It is worth noting that in

the case of both Japan and Iraq, the League of Nations and the

United Nations (“U.N.”), respectively, took the position that

those states were engaged in violations of the 1925 protocol.236

The Iran-Iraq War started in 1982, and by early 1984 the

press was reporting Iranian allegations regarding Iraqi use of

toxic chemical weapons.237 By mid-1984, a U.N. investigating

mission found evidence of Iraqi use of nerve agents.238 In early

1986, in light of Iranian allegations of renewed Iraqi use of

chemical weapons, and threats to retaliate in kind, the Security

Council passed Resolution 582 noting that:

[B]oth the Islamic Republic of Iran and Iraq are parties to

the Protocol for the Prohibition of the Use in War of

Asphyxiating, Poisonous or Other Gases, and of

Secretary-General on March 7, 1986.241 Medical observations,

chemical analysis, and examination of unexploded munitions

demonstrated unquestionable and extensive Iraqi use of mustard

gas.242 The Iraqi use of chemical warfare against Iran was the only

extensive use of such weapons in a major war since World War I.

However, it was not the only time that use of such weapons was

considered.

As has been discussed above, following World War I there

was a considerable lobby in various militaries for the

development of, possession of, and preparation to use chemical

weapons.243 In addition to German weapon developments, the

World War II Allies possessed and deployed extensive stocks of

chemical weapons,244 and were prepared to use them if necessary

(although the definition of “necessity” varied).245

Following the end of World War II, the principal developers

and stock-pilers of chemical weapons were the United States and

the Union of Soviet Socialist Republics (“U.S.S.R.”).246 Both sides

used prior German research and their own development work to

test and deploy both the G-series of nerve gases, and the V-series

in reprisal for chemical attack. In fact, he overruled a plan to use mustard against the

Japanese on Iwo Jima. See COLONEL JOSEPH H. ALEXANDER, CLOSING IN: MARINES IN THE

SEIZURE OF IWO JIMA 48 (1994). In contrast, U.K. Prime Minister Winston Churchill

several times urged the use of mustard gas, stating, “I want a cold-blooded calculation

mustard . . . . I want the matter studied in cold blood by sensible people and not by that

actors towards signing and ratifying two new conventions: (1) the

increasing and real possibility of actual use in warfare; (2)

The United Kingdom, United States, and Russian Federation are

the BWC’s depositaries.255

States parties to the BWC undertake “never in any

circumstances to develop, produce, stockpile, or otherwise

acquire or retain” the following class of substances:

microbial or other biological agents, or toxins whatever their

origin or method of production, of types and in quantities

that have no justification for prophylactic, protective or

other peaceful purposes; [or] weapons, equipment or means

of delivery designed to use such agents or toxins for hostile

purposes or in armed conflict.256

As noted above, both the BWC and the CWC incorporate the text

of the Geneva Protocol.257 That incorporation is important for

several reasons discussed above,258 but it also operates as a gapfiller

in any potential areas of doubt where an argument might

be made that an engineered virus was not the equivalent of

nanomachines,259 and not yet a living thing intended to fall

within the BWC.260 In fact, the BWC and CWC overlap because

they both incorporate the Geneva Protocol and because they

both cover toxins.261 This overlap and incorporation must inform

259. At least some experts have informed the Author that engineered viruses are,

for all intents and purposes, nanomachines. This information was obtained at a

conference with the Author on July 8, 2009, in Washington D.C., in which he agreed to

keep confidential the names of participants and specific quotations.

260. For two reasons, there is no doubt the BWC could be fairly interpreted to

include even engineered viruses: 1) the inclusion of smallpox within the BWC even

though a virus is not per se a living thing; 2) the generally accepted scientific conclusion

that a virus is in fact a biological entity. See Robert Edwards & Forest Rohwe, Viral

Metagenomics, 3 NATURE REVIEWS MICROBIOLOGY 504 (2005). Given the potentially grave

consequences of the use of engineered viruses as weapons, it is important that we

interpret the BWC as covering their usage for banned purposes.

261. There is overlap between biological warfare and chemical warfare as the use in

war of toxins, whether produced by living organisms, or otherwise, is banned under the

provisions of both the BWC and the CWC. Considerable interpretative value may be

found in definitional section of the relevant U.S. statute. 18 U.S.C. § 178 2–4 (2006)

defines criminally banned biological weapons:

(2) the term "toxin" means the toxic material or product of plants, animals,

microorganisms (including, but not limited to, bacteria, viruses, fungi,

rickettsiae or protozoa), or infectious substances, or a recombinant or

synthesized molecule, whatever their origin and method of production, and

are legal uses intended for peaceful purposes.267 The treaty’s

categorical prohibition of chemical weapons is administered by

the Organisation for the Prohibition of Chemical Weapons

(“OPCW”),268 which conducts inspection of military and

industrial plants in all of the member nations, and works with

stockpile countries. All parties are also required to submit a

declaration concerning their possession of current chemical

weapons, old chemical weapons, and production facilities upon

sighning the treaty.269

The CWC identifies three classes of controlled chemicals

which can either be used as weapons or in the manufacture of

weapons.270 Classification is based on the quantities of the

substance produced commercially for legitimate purposes.271

Each class is split into two parts: part A covers chemicals that can

be used directly as weapons and part B extends coverage to

chemicals useful in the manufacture of chemical weapons.272 The

annexes and schedules incorporated within the CWC provide the

criteria for defining these groups of chemicals.273 Chemicals

listed in schedule 1 have few or no uses outside of chemical

weapons;274 while production or use of these chemicals may be

permissible for research, medical, pharmaceutical, or chemical

purposes directly related to protection against toxic chemicals and to protection against

chemical weapons; (c) Military purposes not connected with the use of chemical

hundred grams per year must be declared to the OPCW.275 Each

country is limited to possessing a maximum of one ton of these

materials.276 Chemicals listed in schedule 2 have legitimate smallscale

applications;277 manufacture of these chemicals must be

declared, and export of these chemicals to non-CWC countries is

limited.278 Chemicals listed in schedule 3 have large-scale

industrial uses apart from chemical weapons.279 Plants that

manufacture more than thirty tons of schedule 3 chemicals per

year must declare the produced quantity and subject themselves

to inspection; additionally, there are restrictions on export of

schedule 3 chemicals to non-CWC countries.280

The treaty also deals with “discrete organic compounds.”281

Unless a plant solely produces explosives or hydrocarbons, the

OPCW must be informed of and may inspect any plant

producing or expecting to produce more than two hundred tons

of discrete organic compounds per year, or thirty tons if the

chemical contains phosphorus, sulfur, or fluorine.

A U.N. publication on disarmament negotiations accurately

reports that:

[T]he Geneva Protocol of 1925 and the Biological Warfare

Convention of 1972 are relatively simple as far as their

content and mechanisms of implementation are concerned.

It became increasingly clear at the beginning of the 1970s

that such a simple approach to a comprehensive ban on

compliance with a total prohibition of chemical weapons

should be more intrusive in order to ensure the security of

all parties to the agreement.282

All parties to the CWC agree never to develop, produce, acquire,

possess, transfer, prepare to use, or use chemical weapons.283

Through its detailed definitions, its declaration requirement,284

and the OPCW, the CWC creates a regime with very broad reach;

the incorporation of the Geneva Protocol and the BWC’s parallel

obligations greatly amplify the probability that most

nanotechnology products with toxic or poisonous application in

war will fall within the CWC’s regime. A number of other

potentially applicable treaties and international law doctrines are

worth at least a brief mention here as well.

B. Other Potentially Applicable Treaties and Doctrines

In addition to the treaties discussed above, a number of

other treaties and binding principles of international law may

impact nanoparticles and nanomimics and their use as weapons

of war.285 There are several treaties that, although not facially

applicable to nanobots, may nevertheless impact their use in

warfare. Similarly, there are also several general doctrines which

may bear on the use of nanobots that are worth mentioning.

1. Geneva Conventions III and IV, and Additional Protocol I of

1977

The Geneva Convention Relative to the Treatment of

Prisoners of War (“Geneva Convention III”)286 and the Geneva

Convention Relative to the Protection of Civilians (“Geneva

Convention IV”)287 include several articles that generally impact

gas warfare in the context of prisoners of war (“POWs”). In

particular, Geneva Convention III requires continued gas

288. Article 18 of the Geneva Convention Relative to the Treatment of Prisoners of

War (“Geneva Convention III”) states the following:

[A]ll effects and articles of personal use, except arms, horses, military

equipment and military documents, shall remain in the possession of prisoners

of war, likewise their metal helmets and gas masks and like articles issued for

personal protection. Effects and articles used for their clothing or feeding

shall likewise remain in their possession, even if such effects and articles

belong to their regulation military equipment.

Geneva Convention III, supra note 286, art. 18. Note that the ICRC interprets Geneva

Convention III as specifically requiring gas protection for prisoners of war:

[T]he requirement that prisoners of war must have shelters against air

bombardment “to the same extent as the local civilian population” implies

that . . . shelters must be supplied for prisoners of war in the same conditions

as for the civilian population . . . . If civilian workers employed in a particular

industry are issued with special equipment for use during air-raids (gas masks,

protective clothing, etc.), such equipment must also be made available to prisoners of

war.

RELATIVE TO THE TREATMENT OF PRISONERS OF WAR 188(Jean S. Pictet ed., 1960)

(emphasis added) (quoting Geneva Convention III, supra note 286, art. 23).

289. Article 85 of the Geneva Convention Relative to the Treatment of Civilians

states the following:

[T]he Detaining Power is bound to take all necessary and possible measures to

ensure that protected persons shall, from the outset of their internment, be

accommodated in buildings or quarters which afford every possible safeguard

as regards hygiene and health, and provide efficient protection against the

rigors of the climate and the effects of the war.

Geneva Convention IV, supra note 287, art. 85. Additionally, article 88 states:

[I]n all places of internment exposed to air raids and other hazards of war,

shelters adequate in number and structure to ensure the necessary protection

shall be installed. In case of alarms, the measures internees shall be free to

enter such shelters as quickly as possible, excepting those who remain for the

protection of their quarters against the aforesaid hazards. Any protective

measures taken in favor of the population shall also apply to them.

Id. art. 88. Furthermore, a 1991 U.N. report concerning Israel’s Geneva Convention IV

obligations to Palestinians in the occupied territories with respect to gas protection

informs this point of inquiry:

Since the inception of the crisis, Iraq had repeatedly threatened to attack

Israel with conventional and non-conventional weapons in the event of

hostilities. As part of its civil defense procedures, Israel provided to its citizens

gas masks and related equipment for protection against a chemical attack. The

Israeli authorities also issued gas masks to the Palestinian residents of

Jerusalem. United Nations officials in the area repeatedly expressed concern

about the need of the Palestinian population as a whole to be given such

equipment. On 14 January 1991, the Israeli High Court of Justice ruled as

follows: “The Military Commander must indeed exercise equality in the area.

He may not discriminate between residents. When the Military Commander has

reached the conclusion that protective kits must be distributed to Jewish residents in the

930 FORDHAM INTERNATIONAL LAW JOURNAL [Vol. 33:858

Other relevant provisions are found in the 1977 Protocol

Additional to the Geneva Conventions of 12 August 1949

(“Protocol I”).290 Although a large part of Protocol I is at least in

some way related to protecting against the utilization of any

weapon,291 certain portions have particular application to the

nanoweapons discussed here. This is particularly true of article

36:

[I]n the study, development, acquisition or adoption of a

new weapon, means or method of warfare, a High

􀀃

area, protective kits must also be distributed to the area’s Arab residents.” The High

Court ordered that

“[F]irst, the 173,000 gas masks presently in stock in emergency

warehouses must be immediately distributed to adults living in the areas

surrounding Jerusalem, as well as in those areas near the Green Line.

Second, all efforts possible should be made to secure masks for the

children of these adults, and these masks must be distributed immediately

upon their being obtained. Third, all residents of the area should receive

masks immediately upon their being purchased by the Military

Commander. The Military Commander must make every possible effort

to secure these masks as soon as possible.”

Despite the urgency expressed in the decision of the High Court, the

distribution of gas masks from Israel’s existing stock proceeded slowly. The

IDF spokesman’s office told B’Tselem, an Israeli human rights organization,

that, as of 2 February 1991, 50,000 masks had been given out. Those that were

distribution lacked the atropine and decontamination powder contained in

the kits provided to Israeli citizens. Few, if any, masks were made available to

Palestinian children. Furthermore, the vast majority of Palestinian detainees -

many of whom are housed in tents and therefore more vulnerable in the event

of an attack—were not given gas masks. For its part, UNRWA launched an

appeal and received, from international donors, 62,000 masks for adults. Its

distribution of the masks was slowed by the fact that the Israeli authorities

requested that they be delivered on a house-to-house basis during the curfews.

While much of the discussion of nanoweapons presented here

argues that they are simply old swine in new battles, to the extent

that nanomimics do indeed represent anything that existing

conventions do not cover, article 36 of Protocol 1 would clearly

require advance determination of their legality. Other relevant

provisions of Protocol I are are those relating to protection of the

civilian populace,293 and precautions required in attacks.294

􀀃

292. See id. art. 36.

293. Article 51 of Protocol I addresses protection of the civilian population:

1. The civilian population and individual civilians shall enjoy general

protection against dangers arising from military operations. To give effect to

this protection, the following rules, which are additional to other applicable

rules of international law, shall be observed in all circumstances.

. . .

4. Indiscriminate attacks are prohibited. Indiscriminate attacks are:

(a) those which are not directed at a specific military objective;

(b) those which employ a method or means of combat which cannot be

directed at a specific military objective; or

(c) those which employ a method or means of combat the effects of

which cannot be limited as required by this Protocol; and consequently,

in each such case, are of a nature to strike military objectives and civilians

or civilian objects without distinction.

5. Among others, the following types of attacks are to be considered as

indiscriminate:

(a) an attack by bombardment by any methods or means which treats as a

single military objective a number of clearly separated and distinct

military objectives located in a city, town, village or other area containing

a similar concentration of civilians or civilian objects; and

(b) an attack which may be expected to cause incidental loss of civilian

life, injury to civilians, damage to civilian objects, or a combination

thereof, which would be excessive in relation to the concrete and direct

military advantage anticipated.

Id. art. 51.

294. Article 57 of Protocol I addresses precautions in attack:

1. In the conduct of military operations, constant care shall be taken to spare

the civilian population, civilians and civilian objects.

2. With respect to attacks, the following precautions shall be taken:

(a) those who plan or decide upon an attack shall:

(i) do everything feasible to verify that the objectives to be attacked

are neither civilians nor civilian objects and are not subject to special

protection but are military objectives within the meaning of

paragraph 2 of Article 52 and that it is not prohibited by the

provisions of this Protocol to attack them;

2. The Early Poison Conventions

The ban on poisonous weapons is an ancient one.295

Instructions for the Government of Armies of the United States

in the Field (“General Order 100”) is the first comprehensive

modern articulation regulating armed conflict.296 it provides,

inter alia, that “the use of poison in any manner, be it to poison

wells, or food, or arms, is wholly excluded from modern warfare.

He that uses it puts him self [sic] out of the pale of the law and

usages of war.”297 However, the stricture dates from well before

the nineteenth century:

[P]roscription of toxic weapons seems almost as ancient as

the weapons themselves. The earliest surviving references to

toxic warfare are probably those in the Indian epics . . . and

it is to the Manu laws of India, which forbade the use of

poison weapons, that a line of ancestry can be drawn . . . . It

is a culturally diverse ancestry, reaching back not only

through Hague and Roman law via Grotius, but also through

the warfare regulations which the Saracens derived from the

Koran.298

􀀃

(ii) take all feasible precautions in the choice of means and methods of attack

with a view to avoiding, and in any event to minimizing, incidental loss or

civilian life, injury to civilians and damage to civilian objects;

(iii) refrain from deciding to launch any attack which may be

expected to cause incidental loss of civilian life, injury to civilians,

damage to civilian objects, or a combination thereof, which would be

excessive in relation to the concrete and direct military advantage

anticipated;

(b) an attack shall be cancelled or suspended if it becomes apparent that

the objective is not a military one or is subject to special protection or that

the attack may be expected to cause incidental loss of civilian life, injury

to civilians, damage to civilian objects, or a combination thereof, which

would be excessive in relation to the concrete and direct military

advantage anticipated;

(c) effective advance warning shall be given of attacks which may affect

the civilian population, unless circumstances do not permit. 3. When a

choice is possible between several military objectives for obtaining a

similar military advantage, the objective to be selected shall be that the

attack on which may be expected to cause the least danger to civilian lives

and to civilian objects.

Thus, article 23(a) of the annex to the Hague Convention

of 1907 Respecting the Laws and Customs of War (“Hargue

Convention IV”) provides that “[i]t is especially forbidden to

employ poison or poisoned weapons.”299 This language, however,

must be balanced against its past interpretations, and states

rejecting any applicability to poisonous or asphyxiating gases.300

According to the International Court of Justice in the Nuclear

Weapons Advisory Opinion, the “prime or even exclusive effect” of

a weapon must be to poison in order to qualify as poisonous

within the meaning of the annex to Hague Convention IV.301

Because these agreements concerned toxic and asphyxiating

gases and smokes, the early bans against poisons were ignored or

distinguished by state usage,302 and in any case have been

superseded by the Geneva Protocol, BWC, and CWC, which are

now the recognized source of international law due to their

specificity and effectiveness.303

devices.”307 These are the most important elements of Amended

Protocol II of the Conventional Weapons Convention: (1) use of

landmines and booby-traps is highly regulated but not banned;308

(2) anti-personnel landmines must be kept in clearly marked and

protected minefields or be equipped with self-destruction and

self-deactivation mechanisms that disarm and render the mines

unusable after a relatively short period of time;309 (3) mines

scattered by aircrafts, artillery, or missiles require self-destruction

and deactivation mechanisms;310 (4) anti-personnel mines must

be detectable by common mine detection equipment to enable

their location and safe removal after a conflict;311 (5) mine

clearing responsibility rests with the government controlling the

territory where mines are located.312

In the past, interest in mines from a chemical weapons

perspective focused exclusively on their use as deployment

devices; however, it is also interesting to look at some of the

definitions in Amended Protocol II of the Conventional Weapons

Convention. Most notably, “booby-trap” is defined more broadly

than “mine.” The definition of mine is “a munition . . . designed

to be exploded,” while the definition of booby-trap is “any device

or material which is designed, constructed or adapted to kill or

injure, and which functions unexpectedly when a person disturbs or

approaches an apparently harmless object or performs an

apparently safe act.”313

The facial argument for coverage of nanomimic devices as

booby-traps—at least in circumstances where they affect a person

performing an apparently safe act, such as breathing—is actually

banning anti-personnel landmines. See id.; see also Convention on the Prohibition of the

rather compelling. Article 3 of Amended Protocol II, which

prohibits deployment against civilians or in an indiscriminate

fashion, bolsters this argument.314

It would be ironic if a nanomachine were specifically

designed to avoid coverage as a chemical weapon and

incidentally fell within the coverage of another international ban.

It is, however, a good point to keep in mind, for upon such

ironies may the law be built.

4. Doctrinal Violations

Interestingly, the preamble of the 1925 Geneva Protocol

states that “the use in war of asphyxiating, poisonous or other

gases, and of all analogous liquids materials or devices, has been

314. Article 3 of Amended Protocol II articulates general restrictions on the use of

mines, booby-traps, and other devices:

1. This Article applies to:

. . .

(b) booby-traps; and

(c) other devices.

. . .

3. It is prohibited in all circumstances to use any mine, booby-trap or other

device which is designed or of a nature to cause superfluous injury or

unnecessary suffering.

. . .

7. It is prohibited in all circumstances to direct weapons to which this Article

applies, either in offence, defense or by way of reprisals, against the civilian

population as such or against individual civilians or civilian objects.

8. The indiscriminate use of weapons to which this Article applies is

prohibited. Indiscriminate use is any placement of such weapons:

(a) which is not on, or directed against, a military objective. In case of

doubt as to whether an object which is normally dedicated to civilian

purposes, such as a place of worship, a house or other dwelling or a

school, is being used to make an effective contribution to military action,

it shall be presumed not to be so used; or

(b) which employs a method or means of delivery which cannot be

directed at a specific military objective; or

(c) which may be expected to cause incidental loss of civilian life, injury

to civilians, damage to civilian objects, or a combination thereof, which

would be excessive in relation to the concrete and direct military

advantage anticipated.

9. Several clearly separated and distinct military objectives located in a city,

town, village or other area containing a similar concentration of civilians or

civilian objects are not to be treated as a single military objective.

Id. art 3. It bears mention that “other devices,” defined as manually-placed munitions

and devices including improvised explosive devices designed to kill, injure, or damage

and which are actuated manually, by remote control, or automatically after a lapse of

time, probably does not include nanoweapons.

justly condemned by the general opinion of the civilized

world,”315 and preamble of the CWC affirms that CWC signatories

are “determined for the sake of all mankind, to exclude

completely the possibility of the use of chemical weapons,

through the implementation of the provisions of this

Convention, thereby complementing the obligations assumed

under the Geneva Protocol of 1925 . . . .”316 Those statements

encapsulate the core of the humanitarian argument against gas

weapons from their inception. The reader should be familiar

with the basic doctrines of military necessity,317 proportionality,318

unnecessary suffering,319 chivalry,320 general war crimes,321

treachery,322 and general “humanitarian law”323 against which all

III. GOOD FAITH PRINCIPLE OF TREATY INTERPRETATION

This Part is not intended to be a general treatise on treaty

interpretation, or on any particular state’s treatment of treaty

interpretation law.325 Rather, it is simply intended to articulate

certain agreed-upon principles of good faith interpretation

which should inform the application of current treaties to new

and developing nanomaterials.326

Article 31 of the Vienna Convention on the Law of Treaties

provides that “a treaty shall be interpreted in good faith in

accordance with the ordinary meaning to be given to the terms

of the treaty in their context and in the light of its object and

purpose.”327 The United States signed the Vienna Convention in

1970328 and voluntarily follows many of its provisions, but it is yet

to gain the advice and consent necessary for ratification within

the U.S. Senate.329 Professor Evan Criddle contends that the

United States is reluctant to ratify the Vienna Convention

because the Supreme Court relies on domestic ratification

materials,330 defers to Executive Branch interpretation, and U.S.

INTERNATIONAL LAW IN TREATY MAKING (Rudiger Wolfrum & Volker Roben eds., 2005)

legal regime: (1) speed; (2) clarity and uniformity; (3) universality of participation; and

(4) flexibility and adaptability. See Hanspeter Neuhold, The Inadequacy of Law-Making by

International Treaties, in DEVELOPMENTS OF INTERNATIONAL LAW IN TREATY MAKING,

be ineffective “because its provisions are ambiguous, or because the obligations it

imposes are not identical for all parties.” Id.

courts more broadly tend to construe treaties in light of domestic

interests.331

While U.S. courts are less likely than courts in many other

states to rely solely on international source materials, they still

espouse the underlying requirement of good faith treaty

interpretation. In Sanchez-Llamas v. Oregon, the U.S. Supreme

Court specifically relied on the good faith requirement: “[T]he

United States ratified the [Vienna Convention on Consular

Relations] with the expectation that it would be interpreted

according to its terms.”332 The Court has also recognized the

good faith requirement in treaties signed with Native American

faith requirement when discussing United States v. Alvarez-Machain, 504 U.S. 655 (1992):

[A]lthough both the majority and dissent apparently accepted that the

Extradition Treaty should be interpreted “in accordance with the ordinary

meaning to be given the terms” and consistent with the treaty’s overarching

“object and purpose,” neither seriously considered the Convention’s

instruction to construe treaties “in good faith.” Informing this assessment of

“good faith” is Article 31(3)(c)’s additional instruction, which enjoins courts

to “take into account . . . [a]ny relevant rules of international law applicable to

the relations between the parties.” Thus, a “good faith” treaty interpretation

would account for “the general principle of international law,” discussed in

Justice Rehnquist’s majority opinion, i.e., “that one government may not

‘exercise its police power in the territory of another state.” The Vienna

Convention incorporates this “general principle” into the Extradition Treaty

by implication. Of course, the Vienna Convention’s interpretive framework

does not operate mechanically, eliminating the need for courts to exercise

“good faith” and sound judgment. Instead, the Vienna Convention’s function

is primarily heuristic [i.e. a “rule of thumb” based on trial and error],

channeling courts’ reasoning toward a circumscribed range of internationally

acceptable treaty constructions.

The most recent word on treaty interpretation by the U.S.

Supreme Court is found in Medellin v. Texas, where the Court

held that an International Court of Justice ruling that a foreign

national had not been informed of his rights under the Vienna

Convention on Consular Relations did not preempt Texas

limitations on filing excessive petitions for habeas corpus.334 That

opinion has occasioned critical commentary relating to treaty

interpretation by the Supreme Court.335

It is fair to say that the principle of good faith interpretation,

and the language of Restatement (Third) of Foreign Relations Law of

the United States, is relevant in applying the Geneva Protocol and

its progeny to nanoweapons. However, in light of past arguments

over the meaning of words in chemical-related treaties,336 the

content of the good faith requirement may be a matter of at least

some controversy. This very concern informs a cautious approach

to any possible ambiguities in international treaties, especially

those regulating armed conflict. It is to the possible ambiguities

and their application to nanoweapons that this analysis now

turns.

IV. GOOD FAITH INTERPRETATION OF CURRENT LAWS

APPLICABLE TO NANOMIMICS

A. Application of Current Treaties

Depending on the circumstances, and the nanomaterials

involved, it ranges from certain to strongly arguable, but not

entirely certain, that the principal treaties at issue here—BWC

and CWC with the incorporated Geneva Protocol—apply.337 The

principal difficulty in achieving the absolute predictability for

which all law strives338 is the historic tendency of states to find any

available loopholes in wartime; these interpretations of law are

rejected by the vast majority of states but still have a certain

plausibility. In the last century, there have been two particular

examples involving use of gas in arguable violation of existing

􀀃

337. Pinson, supra note 33, argues that because the BWC bans toxins “whatever

their origin or method of production,” that it therefore “seems to include so-called

mechanical devices that could result from mature nanotechnology [and so] one can

argue that [a] nanorobot[] can be treated as a toxin if it causes harm similar to other

already known toxins.” Id. at 298. He goes on to recognize a counterargument that the

BWC “seems to deal only with biological organisms” and concludes that “[p]erhaps the

only way nanotechnology can fall under the BWC’s prohibitions without a doubt as if it

were used to artificially create exact replicas of known biological weapons or toxins.” Id.

His examination of CWC applicability is equally jejune. He essentially argues that while

nanoproducts “may not be chemicals in the sense originally conceived of by the CWC

drafters, nanotechnology might still be perceived as a functional equivalent and thereby

covered under the CWC.” Id. at 302. Without any in-depth analysis, he concludes that

“nano-germs” and “nano-assassins” “could be prohibited as a toxic chemical under the

CWC, as they would have no purpose other than causing harm or death to humans or

animals.” Id. Pinson concludes that the BWC and CWC are inapplicable, without

mentioning the CWC’s applicability to analogous devices under the Geneva Protocol or

the most likely scenario where existing chemical products are reduced to nanoscale to

defeat defensive systems, and then proceeds to argue for the creation of a new

international treaty. Id. at 302–09. He argues that “because of the vagueness of the word

“chemical,” any country can contend that nanotechnology is not chemical and therefore

not prohibited.” Id.

bans: Germany in World War I and the United States in

Vietnam.339

Germany’s use of gas on a large scale commencing in 1915,

the German legal analysis, and the ensuing argument regarding

violation of the Hague ban, has been discussed above.340 As

Haber notes, Germany “argued at the time and later, that (i) the

Conventions did not cover gas blown from cylinders, (ii) the

Allies had used gas first, (iii) gases were not poison, and (iv) after

the war, gas shells were implicitly excluded because they were not

causing needless suffering . . . .”341 There were certainly

ambiguities in the then-existing treaties and all sides mercilessly

exploited them.342 However, the German case is not the only

instance of a technical legal argument exploiting treaty ambiguity

to justify the use of gas in an armed conflict. The United States

adopted the same approach with respect to its use of tear gas

during the Vietnam War.343

In some ways, the U.S. argument regarding tear gas in

Vietnam was an even further stretch than Germany’s in World

War I: First, the treaty drafters’ intent in 1925 seems considerably

clearer than the general principles espoused at the Hague

Conventions prior to World War I.344 Second, there was even

debate. See, e.g., supra note 137 and accompanying text. The Allies certainly used banned

gases after 1915 in reprisal.

more general agreement among major powers that tear gas was

banned as a weapon of war.345 Importantly, however, the United

States did not ratify the Geneva Protocol until after the end of its

participation in the Vietnam War,346 and tear gas on its own was

much less noxious than other chemical weapons.347 Nevertheless,

given the general U.S. attachment to the English language, there

is a certain air of unreality in basing its argument on the French

language version of the Geneva Protocol.348 In any case, both

examples demonstrate that it is wise to closely read any treaty

purporting to govern new weapons technology.

1. Application to Nanoparticles

Certainly, the treaties are applicable to nano-sized particles

of substances covered by existing conventions. The CWC by its

language applies to “toxic chemicals and their precursors, except

where intended for purposes not prohibited under this

Convention, as long as the types and quantities are consistent

with such purposes.”349 A toxic chemical is “any chemical which

through its chemical action on life processes can cause death,

temporary incapacitation or permanent harm to humans or

animals.”350 Most importantly, “[t]his includes all such chemicals,

regardless of their origin or of their method of production, and

regardless of whether they are produced in facilities, in

munitions or elsewhere.”351

2010] NANOTECH AGENTS 943

It is clear that the CWC bans any existing or future chemical

weapons, including nano-sized particles, that are asphyxiating,

vesicant, nerve agents, or lachrymatory, regardless of the physical

form that they take (i.e. gas, liquid, solid), unless they fall into

one of the CWC’s enumerated exceptions.352 Although the actual

physiological effects of nano-sized particles of a banned

substance might be different and are probably more severe, the

chemical content remains the same; such material

unquestionably falls within the relevant schedules.353 The same

absolute ban also applies to nano-enhanced delivery systems of

such materials.

2. Application to Nano Delivery Systems

Cancer researchers “now use nanoscale devices as drug

delivery vehicles.”354 That nanoscale devices can deliver toxic

chemicals to specific cells in such sufficient quantities should

immediately raise concerns about the use of nanotechnology to

deliver banned chemical weapons. It is clear, though, that the

CWC, which covers the toxic content of these carriers, should

also cover these delivery devices.

The CWC provides that “‘Chemical Weapons’ means the

following, together or separately: . . . (b) Munitions and devices,

specifically designed to cause death or other harm through the

toxic properties of . . . toxic chemicals . . . which would be

released as a result of the employment of such munitions and

􀀃

limited to those which can be justified for such purposes; and . . . the

aggregate amount of such chemicals at any given time for such purposes is

equal to or less than 1 tonne; and . . . the aggregate amount for such purposes

acquired by a State Party in any year through production, withdrawal from

chemical weapons stocks and transfer is equal to or less than 1 ton.

Id., Annex on Implimentation and Verification, pt. VI(A)(1)–(2).

352. The CWC drafters defined chemical weapons so broadly in order to prohibit

possession of all known, unknown, and future toxic chemicals, in types and quantities

that cannot be justified for permitted purposes. For this reason, the chemical weapons

definition captures both novel and traditional chemical agents. See Chemical Weapons

Convention: Hearing on Treaty Doc. 103-21 Before the Comm. on Foreign Relations, 103d

Cong. 37 (1994) (statement of J. Stephen Ledogar, U.S. Rep. to the Conference on

devices . . . .”355 Devices designed to cause death or other harm

through release of toxic chemicals is a clear description of nano

delivery systems when used to deliver banned substances. That

coverage is unquestionable when compared and contrasted with

the 1925 Protocol which is incorporated into the CWC.

The Geneva Protocol bans “asphyxiating, poisonous or

other gases and . . . all analogous liquids, materials or devices.”356

As was demonstrated above, the “analogous device” language in

the Geneva Protocol springs from the original drafters’ concern

with asphyxiating and toxic materials other than gas.357 Its

inclusion in the CWC, along with the specific ban on

“‘[m]unitions’ and ‘devices’ [that release] toxic chemicals,”

represents explicit recognition that (1) such devices needed to

be separately banned and (2) the Geneva Protocol’s prohibition

on analogous devices dealt with something other than delivery

systems.358

The CWC undeniably bans nanodevices designed to cause

death or other harm through the release of toxic chemicals,

except in certain limited circumstances. Inevitably, many of these

devices have the capability of serving both innocent and

dangerous functions.359 But the CWC indisputably does not ban

nanodevices that operate within legal parameters.360

Even in light of the analysis presented thus far in this

Article, a principal issue remains: do the relevant conventions—

CWC, BWC, and the Geneva Protocol incorporated into both—

taken together act to absolutly ban the production and use of

nano-sized devices that can mimic banned chemicals, microbial

or other biological agents, or toxins? Are “nanomachines . . .

Convention”?361

3. Application to Nanomimics

It is highly likely that the CWC, BWC, and Geneva Protocol

together apply to nano-sized mechanical mimics. The arguments

for their coverage are not just persuasive; in the Author’s opinion

they are so compelling that any attempt to avoid their coverage

would rise to the level of breaching requirement of good faith

interpretation.

The arguments for their coverage consist of the following

factors: (1)the Geneva Protocol drafters’ intent; (2) the CWC

and BWC drafters’ intent; (3) textual comparison of the three

conventions; (4) that all of these weapons cause a chemical or

biological reaction; and (5) international law’s good faith

requirement with respect to treaty interpretation. Each argument

is independently compelling, but taken together they are

overwhelming.

a. Drafters’ Intent in the Geneva Protocol

As discussed above, the language of the Geneva Protocol was

taken directly from the Treaty of Versailles, and the Washington

Submarine Treaty was specifically informed by the existence and

effective use of chemical weapons other than gases in World War

I.362 It is clear that the drafters were aware of the problems

caused by fine particles capable of passing through protective

masks that neutralize gases, recognized the distinction between

“processes” and “devices” but deliberately chose to describe

actual toxic weapons as devices, and were fully capable of

including—and did include—a delivery device as a separate

banned weapon where they thought it appropriate.363 It therefore

􀀃

361. MCGUINNESS, supra note 3, at 27.

362. See BERNAUER, supra note 147.

363. See supra Part II.A. Hence, we see the inclusion of “flammenwerfer” in several

of the post-World War I treaties. See supra notes 164–66. Note that a flamethrower is a

device for delivering burning fuel, Dewar supra note 166, at 47–48, and that a later ban

of incendiary weapons paints in broad definitional strokes “any weapon or munition

which is primarily designed to set fire to objects or to cause burn injury to persons

through the action of flame, heat, or combination thereof, produced by a chemical

reaction of a substance delivered on the target” (thought it also includes a specific

946 FORDHAM INTERNATIONAL LAW JOURNAL [Vol. 33:858

becomes clear that the decision to include and retain “analogous

devices” alongside the ban on poisonous and asphyxiating gases

was a deliberate ban on wartime use of any weapon analogous to

asphyxiating or toxic gases. Nanomimics are precisely analogous

to poisonous and asphyxiating gases364 and the Geneva Protocol’s

incorporation into later conventions and treaties—particularly

the CWC and BWC—strengthens this argument.

b. Drafters’ Intent in the CWC and BWC

The CWC negotiations were long and detailed,365 in part

because the negotiators were specifically concerned with

avoiding both evasive conduct and outright cheating.366 As a

result, the CWC contains broad, specific, positive, and negative

requirements; a mechanism for continued verification of

compliance; and analysis of possible new violations.367

Given the high levels of distrust during the Cold War, it was

probably inevitable that interim confidence building measures

and bilateral treaty negotiations were necessary to achieve what

eventually became the CWC.368 The long negotiations and

interim steps, however, resulted in a treaty providing

comprehensive coverage, including prohibition of new research

and development.369 They also created an ongoing international

body to monitor new developments and means of production.370

The BWC is considerably less detailed than the CWC but its

coverage is at least as broad.371 Its core is found in article 1, which

provides in its entirety:

Each State Party to this Convention undertakes never in any

circumstances to develop, produce, stockpile or otherwise

their origin or method of production, of types and in

quantities that have no justification for prophylactic,

protective or other peaceful purposes;

(2) Weapons, equipment or means of delivery designed to use

such agents or toxins for hostile purposes or in armed

conflict.372

While there has been some “push back” in later negotiations

from states concerned that BWC interpretation might interfere

with legitimate research,373 general consensus has emerged in

favor of absolute bans on any new biological weapons in whatever

form they might emerge.374 The negotiating history of the BWC

modern warfare. Many states maintained chemical weapons in their arsenals to deter the

use of this type of weapon against them, and to provide a retaliatory capability if

deterrence failed. Many of these nations, the United States pointed out, would be

reluctant to give up this capability without reliable assurance that other nations were not

developing, producing, and stockpiling chemical weapons. While the United States did

not consider prohibition of one of these classes of weapons less urgent or important

enforcement mechanisms of the CWC. The ban on “microbial or

other biological agents, or toxins,”377 together with their means

of delivery, covers all new genetic development and manipulation

of potential living weapons and their products.378 Taken together

with the CWC, this regime was certainly intended to broadly

cover the development of new chemical and biological weapons.

That is even more apparent when their text is compared and

contrasted.

c. Textual Comparison of the Three Treaties

breadth of coverage. Among the contracting parties the Geneva

Protocol constitutes a “prohibition of . . . the use in war of

asphyxiating, poisonous or other gases, and of all analogous

liquids materials or devices [and] use of bacteriological methods

of warfare.”379 The BWC’s major leap was, of course, banning

development, production, or possession of an entire class of

weapons, not just limiting its prohibition to uses in war.380 Of key

import here is the agreement “never to develop [biological weapons]

whatever their origin or method of production,”381 nor to develop

“equipment or means of delivery designed to use such agents or

toxins.”382 Taken together, the language of the Geneva Protocol

and BWC cover a multitude of weapons and situations in

wartime. It took another twenty years, however, for the CWC to

close the circle on possession and development of chemical

weapons.

In addition to incorporating the Geneva Protocol,383 the

CWC covers three key areas relating to this Article’s analysis: (1)

banning development, production, and possession of chemical

weapons;384 (2) defining chemical weapons to include delivery

systems;385 and (3) clarifying that peaceful development of, inter

alia, pharmaceutical, medical, and agricultural chemicals, is not

impacted.386 Of key importance here is the definition of “Toxic

Chemical:”

any chemical which through its chemical action on life

processes can cause death, temporary incapacitation or

permanent harm to humans or animals. This includes all

such chemicals, regardless of their origin or of their method

of production, and regardless of whether they are produced

in facilities, in munitions or elsewhere.387

This definition certainly covers any toxic chemical, whatever

its dosage, as long as it “can cause” any of the effects listed.388

Taken together with the ban on “. . .devices, specifically designed

to cause death or other harm through the toxic properties of

those toxic chemicals[,]”389 there can be no honest argument

that the CWC on its face does not cover banned chemicals in

nano dosages, and nano sized delivery systems of such chemicals.

The only possible open question is the coverage of

speculative nanobots. And yet, both the BWC and CWC

incorporate the Geneva Protocol and its ban on the use of

“analogous devices” in war.390 Must one fall back on that

language as prohibiting use but not possession? There are two

arguments which may take this question past that point to a

complete ban. The first is that a common factor of all the

nanoweapons discussed here is their effects on the human target.

d. Commonality of Chemical and/or Biological Reactions

All of the nanoscale weapons discussed in this Article

eventually directly affect a human target through biological or

chemical processes.391 At the nanoscale, there is considerable

391. It is, of course, possible to posit nanoscale weapons which only indirectly affect

humans by, for example, damaging other animals, machines or plants. For example,

using emergence technology, simple nanoscale bots could swarm onto all ball bearings

in a specified geographic area, effectively shutting down most mechanical systems. Such

weapons are simply beyond the scope of this Article.

cross-over among chemistry, biology, and physics.392 To the

extent that the hypothetical nanobot in the AEPI’s scenario393

interacts in the human body at a cellular level in a way designed

to mimic a toxic chemical, biological weapon, or toxin,394 it

seems functionally indistinguishable from the substances and

materials banned in the treaties discussed above.

The real question is whether such functional equivalence is

sufficient as a matter of international law395 to ban states party to

the treaties from developing, possessing, or using nanomimics.

That is largely a matter of good faith.

e. Good Faith Requirement for Treaty Interpretation

A good faith requirement in interpretation of treaties is

central to international law.396 The Vienna Convention’s

requirement of interpretation “in good faith in accordance with

the ordinary meaning to be given to the terms of the treaty in

their context and in the light of its object and purpose”397 seems

particularly relevant to attempts to avoid weapons bans by

building a device to mimic a banned chemical or toxin. Even the

following problematic approaches that states have taken to avoid

treaty bans do not represent the actual creation of a killing

device to function identically to an admittedly banned weapon:

Germany’s arguments that the Hague Convention banned the

release of asphyxiating gases from artillery shells but not from

cylinders, and the U.S. argument that the French language

version of the Geneva Protocol and its predecessor trumped the

394. Several informed persons have argued to the Author that for the foreseeable

future, only engineered viruses would be able to behave in this way. Viruses are not, of

course, living things, and yet the BWC clearly covers their development, possession or

and use as weapons. If engineered viruses are, in fact, the only entities capable of

behaving this way, it is indisputable that the BWC applies to these nanobots. If other

forms of nanobots become feasible or foreseeable, a different analysis will apply.

395. In some instances international law recognizes the doctrine of functional

equivalence. See, e.g., David Marcus, Famine Crimes in International Law, 97 AM. J. INTL L.

245, 262–64 (2003) (arguing that international law should extend to man-made famines

since “famines are often functionally equivalent to genocide”).

English language version to create an ambiguity that allowed for

use of tear gas in war.398

If the good faith requirement is to have any validity at all in

international law, it must apply to ban the use of nanomimics as

weapons. Given states’ past attempts to evade existing bans, it is

still appropriate at least to consider pursuing past proposals for

new treaties implementing new bans, and to considering

clarifying the pertinent treaties through minor modification.

B. Is There A Need For A New Convention?

Several authors have discussed drafting new conventions or

modifying the CWC and BWC.399 In an interesting article that

unfortunately ignores some of the fundamental approaches to

understanding the law of armed conflict, Sean Howard suggests

that there are only “two basic options for designing a possible

arms control approach to the mass-destructive potential of

nanotechnology:” (1) to create a “regime of control and

restraint” over the technology; or (2) to totally ban the

technology.400 Howard suggests “a rough transposition of the

Outer Space Treaty [to seek] peaceful exploitation . . . of the

nanosphere.”401 But Howard seems to ignore possible alternative

arms control and technology models—most obviously the CWC—

and the possibility of simply modifying existing conventions.

Indeed, simply modifying the BWC and CWC might be the

easiest course of action.

Jurgen Altmann suggests that while changing the wording of

the CWC might be difficult, it would be useful to clarify that

“[t]oxic substances that are not of biological origin or are not

produced by biological systems would not count as toxins, but

would fall under the CWC, i.e. be prohibited if directed against

humans or animals.”402 Altman also suggests “preventive arms

control” in the form of technology limits.403 This approach seems

flawed, given general resistance to absolute technology limits,404

and the United States’ specific opposition to limits on potential

nanotechnology developments.405

In his discussion of a regulatory approach, Reynolds suggests

a number of useful approaches, including building “inherent

safety” into any living nanotech product through “genome

encryption.”406 Many of his suggestions closely follow the

Foresight Guidelines articulated by the Foresight Institute, which

studies and discusses nanotech issues.407 While the Foresight

Institute makes certain leaps of scientific faith408 about the

potential problems, from an academic view, their solutions are

well-conceived on a national basis. They do not, however,

approach the weapons regulation problem in a way the Author

considers viable in the current international legal system; they

will not limit willing proliferators. The Foresight Institute

recognizes that possibility:

Adding particular weapons related applications of MNT

[molecular nanotechnology] to the list of technologies

covered in Chemical, Biological and Nuclear Weapons

treaties may be appropriate in certain cases. It should be

remembered, however, that the capabilities of productive

nanosystems will be extensions of general manufacturing

technology. The military applications of MNT will include

the manufacture of high performance aerospace vehicles

and precision munitions at low cost. The high value and dual

use of MNT for civilian and defense purposes will require

making distinctions between the enabling technology and its

specific applications, balancing health and economic

benefits against security concerns. Since nanotechnology

research is now global, the security challenges will be

present, with or without the ability to capture the wide

variety of benefits.

Indeed, given the speed with which technology is changing, it seems best to make

limiting language as broad as possible which the drafters of the original conventions

certainly did intentionally.

Overly restrictive treaties or regulatory regimes applied to

core MNT technologies could lead to the unintended

consequence that only the rule-following nations would be at

a competitive disadvantage technologically, economically,

and militarily. While most nations, companies, and

individuals are likely to adhere to reasonable safety

restrictions, guidelines that are viewed as too restrictive will

simply be ignored, paradoxically increasing risk. In addition,

not all guidelines and laws will be followed, and enforcement

is rarely perfect. Non-state actors could become quite

significant, particularly when the relevant knowledge and

raw materials are available globally. They may well not be

signatories to any agreement. While a 100% effective ban

could, in theory, avoid the potential risks of certain forms of

molecular nanotechnology, a 99.99% effective ban could

result in development and deployment by the 0.01% that

evaded and ignored the ban. For example, the international

Biological Weapons Treaty was being violated on a massive

scale even before the ink was dry.409

The Foresight Institute and others miss the essential point—

that the BWC and CWC, taken together and in light of their

incorporating the Geneva Protocol, almost certainly do cover the

sorts of nanodevices with which the Foresight Institute is most

concerned.410 Drafting an entirely new treaty is unnecessary, and

would waste time and effort. Nevertheless, these concerns are

legitimate and worth considering.

There is no real need for specific language changes to the

BWC and CWC. However, if history serves as any guide, the

CWC’s section of definitions could clarify the intent to include

nanomimics or other nanobots; the BWC would not require

more than one or two additional words in its prescriptions to

clarify its intent. As long as the intent is made clear enough to

avoid evasion of already existing coverage of nanomimics, the

wording can be flexible.

Under one possible approach, article 2 of the CWC could be

modified. The revised CWC would read as follows:

1. “Chemical Weapons” means the following, together or

separately: (a) Toxic chemicals or their equivalents including

any analogous devices and their precursors or their equivalents

including any analogous devices, except where intended for

purposes not prohibited under this Convention, as long as

the types and quantities are consistent with such purposes.411

Under a similar approach, article 1 of the BWC could be

modified. The revised BWC would the read:

[E]ach State Party to this Convention undertakes never in

any circumstances to develop, produce, stockpile or

otherwise acquire or retain: (1) Microbial or other biological

agents, or toxins, or their equivalents including any analogous

devices whatever their origin or method of production, of

types and in quantities that have no justification for

prophylactic, protective or other peaceful purposes.412

Such changes are superfluous given the Geneva Protocol’s

incorporation into both the BWC and CWC. Accordingly, the

actual wording and placement of any changes are largely

immaterial; more important is that any new language clarify that

the intent of the states party is to prevent any evasion of the

prohibition on devices and materials analogous to banned

weapons, and that their use in war remain forbidden regardless

of their shape and form.

CONCLUSION

The Great War changed the world in ways unparalleled

before 1918. Although some earlier wars had global reach, three

factors at play in World War I created a new reality of massinvolvement:

(1) advances in science and communications;413 (2)

global participation;414 and (3) total mobilization.415 The

concomitant result of that mass mobilization, however, was

almost universal war weariness when the guns were silenced.416

that was utilized, translated almost inexorably into state policy

and international law.417 Much of the following decade’s

lawmaking was lost in the economic devastation and cultural

insanity of the 1930’s, but the absolute ban on use of chemical

weapons essentially held its own.418

The foresight of those who drafted the initial ban on

“analogous devices” at Versailles now seems almost accidental

and providential, but, in fact, the language was created by hardheaded

men based on hard experiences and hard science.419 The

development of the ban, its culmination in the Geneva Protocol,

and its incorporation into the BWC and CWC, leave no genuine

room for play in any sort of legitimate, good faith argument

about nanomimics, and none whatsoever for any other type of

chemical or biological nanoweapons.

As a matter of practical science and governing international

law, there is really no justifiable argument that any of these

potential nanoweapons are uncovered by existing law; but it

would certainly do no harm to modify both the BWC and CWC to

include supplementary language making clear that the states

parties intend to cover all new forms of analogous weapons. In

fact, that just might do the world some good.
