The following presentation was given at the 1818th
Stated Meeting of the American Academy of Arts and Sciences, held at
the House of the Academy in Cambridge, Massachusetts on January 13,
1999, and was originally published in the 1999 May/June issue of the
American Academy of Arts and Sciences Bulletin. The Problem of Biological
Weapons featured here is the latest version with slight modifications
by Professor Meselson.
Introduction: Carl Kaysen, David W. Skinner Professor of Political
Economy Emeritus, Massachusetts Institute of Technology
NO one has more distinguished qualifications
for speaking in an authoritative, informative, and stimulating way about
biological weapons than does Matthew Meselson. He is a biological scientist,
a student of warfare, a reflective observer, and an effective participant
in the national and international political processes that shape war
and peace.
Matt received his undergraduate education in liberal arts from the
University of Chicago and moved on to graduate study in physical chemistry
at the California Institute of Technology, where he received his Ph.D.
in l957. After appointments as a research fellow, assistant professor
of chemistry, and senior research fellow in chemical biology at CalTech,
he came to Harvard in 1961 as an associate professor of molecular biology.
In l964 he became a full professor and in l976 was appointed Thomas
Dudley Cabot Professor of the Natural Sciences.
His scientific research, I am told, covers a broad range of problems
in molecular genetics. In an important early experiment, Matt and Franklin
Stahl demonstrated that in the division of a bacterial cell, one strand
of the DNA double helix goes to each daughter molecule, thus preserving
the parental genetic code in each and demonstrating how DNA replicates.
Working with invertebrates of the phylum Rotifera, Matt is currently
studying how sexual reproduction is maintained in evolution.
The awards and honors for his scientific work constitute a long list,
including the Thomas Hunt Morgan Medal of the Genetics Society of America,
the Eli Lilly Award in Microbiology and Immunology, and the National
Academy of Sciences Prize in Molecular Biology. He holds honorary degrees
from Chicago, Columbia, Princeton, and Yale Universities and is a member
of the National Academy of Sciences, the American Philosophical Society,
the Royal Society, the Academie des Sciences (Paris) and the Accademia
Sanctae Clarae (Genoa). He was elected to the American Academy of Arts
and Sciences in 1962.
For more than three decades, Matt has had an active interest in the
threats posed by chemical and biological warfare. Demonstrating the
same energy, persistence, and inventiveness in this domain as he does
in science, he has been a consultant to government agencies, a leader
in nongovernmental efforts to deepen public understanding of the potential
threats of chemical and biological weapons, and a force in both pushing
and helping governments to participate in arms control agreements. About
these activities I can speak from my own knowledge and observation.
Jointly with Julian Robinson of the University of Sussex, Matt has
directed the Harvard Sussex Program on CBW Armament and Arms Limitation.
To deepen his own understanding of these weapons and the context of
their potential use, he created and for two years taught a Harvard course
on conventional warfare.
Matt's notable achievements in the domain of arms and arms control
include the following:
He demonstrated that the l979 anthrax epidemic in Sverdlovsk resulted
from a release of an anthrax aerosol from a Soviet military enclave,
killing people as much as 5 kilometers distant and sheep as much as
50 kilometers away.
He disproved US charges of biological warfare in Laos and Cambodia
in the late 1970s and early 1980s. In early 1982 Alexander Haig, then
secretary of state, accused the Soviets of providing North Vietnam with
biotoxins that were subsequently released from the air over Laotian
and Cambodian villages. Later in the year, the charges were repeated
by Haig's successor, George Schultz, and widely publicized by the Reagan
administration as examples of Soviet violations of arms control agreements.
In a tour de force of biochemical, zoological, botanical, and forensic
investigation, Matt showed that the so-called yellow rain was nontoxic
bee excrement discharged in flight and that the initial reports of toxins
could not be verified in further tests. An international conference
held at the House of the Academy in April l983 helped establish these
conclusions.
He undertook a major role in mobilizing expert and public opinion in
support of US ratification of the Chemical Weapons Convention in l994,
the year it went into effect.
Matt continues to pursue these efforts, inter alia, as a member of
the Academy's Committee on International Security Studies. In recognition
of his work, he has been honored with the Public Service Award of the
Federation of American Scientists, the Leo Szilard Award of the American
Physical Society, and the Scientific Freedom and Responsibility Award
of the American Association for the Advancement of Science.
The Problem of Biological Weapons
Presentation: Matthew Meselson, Thomas Dudley Cabot Professor
of the Natural Sciences, Harvard University
EVERY major technology -- metallurgy, explosives,
internal combustion, aviation, electronics, nuclear energy -- has been
intensively exploited, not only for peaceful purposes but also for hostile
ones. Must this also happen with biotechnology, certain to be a dominant
technology of the coming century?
Such inevitability is assumed in The Coming Explosion of Silent
Weapons by Commander Steven Rose (Naval War College Review, Summer
1989), an arresting article that won awards from the US Joint Chiefs
of Staff and the Naval War College:
"The outlook for biological weapons is grimly interesting. Weaponeers
have only just begun to explore the potential of the biotechnological
revolution. It is sobering to realize that far more development lies
ahead than behind."
If this prediction is correct, biotechnology will profoundly alter
the nature of weaponry and the context within which it is employed.
During World War II and the cold war, the United States, the United
Kingdom, and the Soviet Union developed and field-tested biological
weapons designed to attack people and food crops over vast areas. During
the century just begun, as our ability to modify fundamental life processes
continues its rapid advance, we will be able not only to devise additional
ways to destroy life but will also be able to manipulate it -- including
the processes of cognition, development, reproduction, and inheritance.
A world in which these capabilities are widely employed for hostile
purposes would be a world in which the very nature of conflict had radically
changed. Therein could lie unprecedented opportunities for violence,
coercion, repression, or subjugation. Movement towards such a world
would distort the accelerating revolution in biotechnology in ways that
would vitiate its vast beneficial application and could have inimical
consequences for the course of civilization.
Is this what we are in for? Is Commander Rose right? Or will the factors
that thus far have prevented the use of biological weapons survive into
the coming age of biotechnology? After all, despite the fact that the
technology of devastating biological weapons has existed for decades,
their only use in war appears to have been that by the Imperial Japanese
Army in Manchuria more than half a century ago.
The longstanding norm against any use of biological weapons serves
not only to constrain the actions of the majority who are influenced
by it, but also to enhance the deterrence of any who may be disposed
to flout it. Whether and under what circumstances Iraq would have used
the biological weapons it was attempting to develop before its Gulf
War defeat in 1991 is unknown. But if Iraq had done so, its very violation
of such a basic and longstanding norm of international behavior would
have widely been seen as justification for drastic reprisal.
A similar history of restraint can be traced for chemical weapons.
Although massively used in World War I and stockpiled in great quantity
during World War II and the cold war, chemical weapons -- despite the
hundreds of wars, insurgencies, and terrorist confrontations since their
last large-scale employment 80 years ago -- have seldom been used since.
Their use in Ethiopia, China, Yemen, and Vietnam (if one includes harassing
agents), and against Iranian soldiers and Kurdish towns are among the
very few exceptions. Indications that trichothecene mycotoxins had been
used in Laos and Cambodia in the 1970s and 1980s proved to be illusory.
Instead of the wave of chemical and biological terrorism some feared
would follow the lethal sarin gas attacks perpetrated by the Aum Shinrikyo
cult in Japan in 1994 and 1995, there has been only a sudden epidemic
of "biohoaxes" and several relatively minor "biocrimes",
undoubtedly stimulated by recent official and media attention to the
potential for use of chemical and biological weapons in terrorism. In
July 1999, five years after the Aum attack in the Tokyo subway, the
Federal Bureau of Investigation reaffirmed that "our investigations
in the United States reveal no intelligence that state sponsors of terrorism,
international terrorist groups, or domestic terrorist groups are currently
planning to use these deadly weapons in the United States".
Whatever the reasons -- and several have been put forward -- the use
of disease and poison as weapons has been extremely limited, despite
the great number of wars and bitter insurgencies that have occurred
since the underlying technologies of the weapons became accessible.
Human beings have exhibited a propensity for the use, even the veneration,
of weapons that bludgeon, blast, or cut, but have generally shunned
and reviled weapons that employ disease and poison. We may therefore
ask if, contrary to the history of other major technologies, the hostile
exploitation of biotechnology can be averted.
The factor that compels our attention to this question is the possibility
that any major turn to the use of biotechnology for hostile purposes
could have consequences qualitatively very different from those that
have followed from the hostile exploitation of earlier technologies.
Unlike the technologies of conventional or even nuclear weapons, biotechnology
has the potential to place mass destructive capability in a multitude
of hands and, in coming decades, to reach deeply into what we are and
how we regard ourselves. It should be evident that any intensive exploitation
of biotechnology for hostile purposes could take humanity down a particularly
undesirable path.
Whether this happens is likely to depend not so much on the activities
of lone misanthropes, hate groups, cults or even rogue governments as
on the policies and practices of the world's leading states.
In the United States, there was abrupt and remarkable change -- from
nearly thirty years of being deeply engaged in the development and production
of biological weapons to the dramatic and unconditional US renunciation
of biological weapons declared by President Nixon in November 1969 and
the US renunciation of toxins three months later. Today the former offensive
biological weapons program of the United States and the logic behind
its abolition are largely forgotten, although there are valuable lessons
to be learned from both.
During World War II, research, development and pilot-scale production
of biological weapons was centered at Fort (then Camp) Detrick, in Maryland.
Large-scale production was planned to take place at a plant near Terre
Haute, Indiana, built in 1944 for the production of anthrax and the
filling of anthrax bombs. Equipped with twelve 20,000-gallon fermentors,
it was capable of producing fill for 500,000 British-designed 4-pound
anthrax bombs a month. Although the United Kingdom had placed an order
for anthrax bombs in 1944 and the plant was ready for weapons production
by the following summer, the war ended without anthrax having actually
been produced.
Contrary to the view that biological weapons are easy to develop, by
the end of the war Fort Detrick comprised some 250 buildings and employed
approximately 3,400 people, some engaged in defensive work but many
in the development and pilot production of weapons. Several years after
the end of the war, the Indiana plant was demilitarized and leased to
industry for production of antibiotics. It was replaced by a more modern
and flexible biological weapons production facility constructed at Pine
Bluff Arsenal, in Arkansas, which began production late in 1954 and
operated until 1969.
A major effort of the 1950s was encompassed under Project St. Jo, a
program to develop, test, produce, and deploy anthrax bombs to Europe
for possible use against Soviet cities. In order to determine quantitative
munitions requirements, 173 releases of noninfectious aerosols were
secretly conducted in Minneapolis, St. Louis, and Winnipeg -- cities
chosen to have the approximate range of conditions of climate, urban
and industrial development, and topography that would be encountered
in the major potential target cities of the USSR. The weapon to be used
was a cluster bomb holding 536 biological bomblets, each containing
35 ml of a liquid suspension of anthrax spores and a small explosive
charge fuzed to detonate upon impact with the ground, thereby producing
an infectious aerosol to be inhaled by persons downwind. In later years,
anthrax was abandoned as a standardized US lethal biological agent and
replaced with a lethal strain of tularemia, a much less persistent and
more predictable agent. Other agents -- the bacteria of brucellosis,
the rickettsia of Q-fever, and the virus of Venezuelan equine encephalomyelitis,
all more incapacitating than lethal, as well as fungi for the destruction
of rice and wheat crops -- were also introduced into the US bioweapons
stockpile, along with improved munitions for high-altitude delivery
and spray tanks for delivery of agents by low-flying aircraft. According
to published accounts these developments culminated in a major series
of biological weapons field tests using various animals as targets,
conducted at sea in the South Pacific in 1968.
Soon after Richard Nixon became president, he ordered a comprehensive
review of US biological weapons programs and policies -- which had been
unexamined and unanalyzed by policy makers for fifteen years. Each relevant
government department and agency was instructed to consider a range
of options and to present its own evaluation. In November 1969 the president
announced that the United States would unilaterally and unconditionally
renounce biological weapons. The US stockpiles were destroyed and the
facilities for developing and producing them were dismantled or converted
to peaceful uses. US biological programs were ordered confined to defensive
purposes, strictly defined. President Nixon also declared that, after
nearly 50 years of US recalcitrance, he would seek US ratification of
the 1925 Geneva Protocol prohibiting the use in war of chemical and
biological weapons. He also announced US support for an international
treaty proposed by the United Kingdom, banning the development, production,
and possession of biological weapons, leading to the Biological Weapons
Convention of 1972.
It is important to note that these US decisions went far beyond the
mere cancellation of a program. They renounced, without prior conditions,
even the option to have biological and toxin weapons. What was the underlying
logic?
First, it had become evident through the results of the US biological
weapons program that deliverable biological weapons could be produced
that would kill people, livestock, and crops over large areas.
Second, it was realized that the US offensive biological weapons program
was pioneering a technology that, although by no means easy to create,
could be duplicated with relative ease once the technology diffused,
making it possible for a large number of states to acquire the ability
to threaten or carry out destruction on a level that could otherwise
be matched by only a few major powers. The US offensive program therefore
risked creating additional threats to itself with no compensating benefit
and was undermining prospects for combating the proliferation of biological
weapons.
The clear policy implication was that the United States should convincingly
renounce biological weapons and seek to strengthen international barriers
to their development and acquisition. The US renunciation of biological
weapons was seen as a major step away from a universal menace. As expressed
by President Nixon in November 1970, "Mankind already carries in
its own hands too many of the seeds of its own destruction."
The l972 Biological Weapons Convention (BWC) entered into force in
1975. It was the first worldwide treaty to prohibit an entire class
of weapons. The BWC now has some 140 States Parties, with the most important
holdouts in the Middle East. Unlike the Chemical Weapons Convention
(CWC) of 1993, it has no organization, no budget, no inspection provisions,
and no sanctions -- only a pledge by states parties never to develop,
produce, stockpile or otherwise acquire or retain biological agents
or toxins of types and in quantities that have no justification
for prophylactic, protective or other peaceful purposes or equipment
designed to use such agents or toxins for hostile purposes or
in armed conflict. The significance of the BWC lies in its creation
of a clear normreinforced by international treatyagainst
even the development of biological and toxin weapons.
While the United States renounced BW and abided by the BWC, the Soviet
Union did not. According to recent statements by officials of the former
Soviet program, it was believed that the US renunciation of BW was a
hoax, intended to hide a secret offensive program. Aware of the major
US investment in biological weapons during the cold war and of the dynamic
US lead in microbiology and biochemistry, the Soviet Union continued
and intensified its preparations to be able to employ biological weapons
on a large scale.
An example was the facility built for the production of anthrax bombs
in the early 1980s at Stepnogorsk, in what is now the independent republic
of Kazakhstan. Recently dismantled under the US Cooperative Threat Reduction
Program, in cooperation with Kazakhstan, it was equipped with ten 20,000-liter
fermentors, apparatus for the large-scale drying and milling of the
agent to a fine powder, machines for filling it into bombs, and underground
facilities for storage of filled munitions. According to its cold war
director, Stepnogorsk conducted numerous developmental and test runs
but never produced a stockpile of anthrax weapons. Nevertheless, there
is no doubt that its purpose was to provide a capability to commence
production on short notice if ordered to do so.
According to the Russian Federations 1992 declaration of its
past BW activities presented to the United Nations under the voluntary
confidence-building agreement among States Parties to the BWC, between
the mid-1960s and 1975 work was done at Sverdlovsk (now Ekaterinburg),
Zagorsk (now Sergiyev Posad), and Kirov on the mass production and dispersion
of biological agents. At the Sverdlovsk facility an accidental release
of anthrax aerosol in April, 1979 is known to have killed nearly 70
people downwind and to have killed sheep in villages out to a distance
of 50 kilometers.
Field testing of aircraft and missile delivery systems for biological
agents was conducted on Vozrozhdeniye Island in the Aral Sea. In a 1998
interview with a Moscow newspaper, the general in charge of Russian
biological defense is quoted as saying that activities at the test site
in the 1970s and 1980s were "in direct violation of the anti-biological
treaty".
The former Soviet facilities at Ekaterinburg, Sergiyev Posad, and Kirov
remain closed to foreigners. US-Russian-British discussions that had
achieved agreement on the principle of reciprocal visits to each other's
military biological facilities as a means of resolving ambiguities have
foundered and are in abeyance. The Russian Federation has done little
to convince other nations that the military core of the Soviet biological
weapons program has been dismantled. Continuing suspicions, together
with the general deterioration in US-Russian relations, stand in the
way of joint efforts to avert a long-term threat to both. While it was
the two cold war superpowers that did most to bring biological weapons
into existence, only the United States, under President Nixon, fully
understood that its best interest was in credible renunciation.
At present, we appear to be approaching a crossroads -- a time that
will test whether biotechnology, like all major predecessor technologies,
will come to be intensively exploited for hostile purposes or whether
instead our species will find the collective wisdom to take a different
course. An essential requirement is international agreement that biological
and chemical weapons are categorically prohibited. With the BWC and
the CWC both in force for a majority of states, including all the major
powers -- and despite the importance of insuring compliance and expanding
the membership of both treaties still further -- the international norm
is clearly established.
The Organization for the Prohibition of Chemical Weapons, established
under the CWC and with a current staff of approximately 200 trained
inspectors, has inspected and sealed all of the world's 60 declared
chemical weapons production facilities and has conducted more than 500
inspections of declared chemical weapons-related facilities and certain
industrial facilities, including inspections of 34 chemical weapons
storage sites holding some 8,000,000 chemical munitions slated for internationally
verified destruction, mainly in the United States and the Russian Federation.
What can international treaties like the CWC accomplish? First, they
define an agreed norm, without which arms limitation cannot succeed.
Second, they act to keep compliant states compliant, even when they
are under pressure to encroach at the limits, potentially eroding the
overall norm. Third, their procedures for declaration and on-site monitoring
and inspection, including challege inspection, pose the threat of exposing
noncompliance and coverup, creating a disincentive for potential violators.
Fourth, exposure by an international treaty organization can make it
politically more difficult for compliant states to ignore violations.
In Geneva, negotiations are underway to strengthen the BWC. There is
broad agreement that there should be mandatory declarations of biodefence
programs and certain facilities and that provision should be made for
challenge investigations of suspected violations, to be conducted by
a new international organization. Some states favor randomly-selected
visits to declared facilities, employing managed access procedures on-site
in order to build confidence in the accuracy of declarations and to
help deter prohibited activities from being conducted under the cover
of dual-use facilities. Others have so far argued for less rigorous
measures. Other important issues, including the substantive and procedural
requirements for initiating a challenge inspection, assistance in protection
against biological weapons, and measures of peaceful scientific and
technical cooperation also remain to be resolved and are presently the
subject of intensive negotiation by the states parties of the BWC.
The prohibitions embodied in the BWC and the CWC are directed to the
actions of states, not individuals. Recently, interest has developed
in the possibility of enhancing the effectiveness of these conventions
by creating international law that would hold individuals -- whether
they be government officials, commercial suppliers, weapons experts,
or terrorists -- criminally responsible for acts that are prohibited
to states by the biological and chemical weapons conventions. A treaty
to create such law has been drafted by an international group of legal
authorities. It is patterned on existing international treaties that
criminalize aircraft highjacking, theft of nuclear materials, torture,
hostage taking, and other crimes that pose a threat to all or are especially
heinous. The draft treaty would make it an offence for any person, regardless
of official position, to order, direct, or knowingly render substantial
assistance in the development, production, acquisition or use of biological
or chemical weapons. A person, regardless of nationality, who commits
any of the prohibited acts anywhere in the world would face the risk
of prosecution or of extradition should that person be found in a state
that supports the proposed convention. International law that would
hold individuals criminally responsible would create a new dimension
of constraint against biological and chemical weapons. Such individuals
would be regarded as hostes humani generisenemies of all humanity.
The norm against chemical and biological weapons would be strengthened,
deterrence of potential offenders, both official and unofficial, would
be enhanced, and international cooperation in suppressing the prohibited
activities would be facilitated.
What we see here -- the non-use of biological weapons; the opprobrium
in which they are generally held; the international treaties prohibiting
their development, production, possession, and use; the initiation of
mandatory declarations and on-site inspection under the CWC and negotiations
that may lead to strengthening the BWC with similar measures; and the
possibility of an international convention to make biological and chemical
weapons offenses international crimes, subject to universal jurisdiction
and applicable even to leaders and heads of statesuggests that
it may be possible to reverse the usual course of things and, in the
century just begun, avoid the hostile exploitation of biotechnology.
Doing so, however, will require wider understanding that the problem
of biological weapons rises above the security interests of individual
states and poses an unprecedented challenge to all.
