CHEMICAL ARMS (WEAPONS) THE TRUTH FROM 1918 TO 2018

Edward M. Spiers, professor of strategic studies at Leeds University, in England, explores both the myths and realities of chemical and biological warfare. Organized more or less
chronologically, Spiers recounts the evolution of chemical and biological weapons from the first mass uses of chemical weapons in World War I to the potential of modern biology to transform bioterrorism.

Spiers writes that chemical and biological weapons have probably been around as long as warfare itself. Ancient European, Indian, and Chinese history is replete with the use of poisonous snakes, insects, diseased animals, incendiaries, poison-tipped weapons, and poisoned water supplies in warfare. The first large-scale use of chemical weapons occurred in World War I, when the Germans discharged chlorine gas from cylinders at Ypres, Belgium, in 1915. 

Reported casualties from the gas ranged from 7,000 to 15,000 people, but after the initial surprise, the Allies were able to improvise protective measures. Within five months, the British were able to retaliate at the Battle of Loos, but they suffered 2,000 casualties to their own gas.

The failures of gas to break the enemy’s lines at Ypres, Loos, and other battles contributed to the legacy of gas warfare in World War I as a failure. However, Spiers argues, this legacy was largely shaped by postwar historians, because few participants shared that view. The use of gas actually increased over the course of the war. In addition to consequent casualties, gas negatively affected morale and considerably contributed to psychological and physical stress. Antigas defenses also made warfare more cumbersome, exacerbating logistical and communication challenges.

As evidence of the effectiveness of chemical weapons, real or imagined, Spiers writes that the Allies prohibited Germany from manufacturing and importing asphyxiating or poisonous
gases as part of the Treaty of Versailles that ended the war. Furthermore, in 1925, 44 nations signed the Geneva Protocol, which prohibited the use of chemical and biological weapons by international law and the “conscience and practice of nations.” Nonetheless, during the period between World Wars I and II, Britain considered but, for largely moral and political reasons, did not use chemical weapons in Egypt, Afghanistan, India, and Iraq.

Winston Churchill himself was “strongly in favour of using poisoned gas against uncivilised tribes,” Spiers writes. The eventual use of gas bombs by the Italians in Ethiopia in 1935–36, however, in direct contravention of the Ge ne va Protocol, reawakened Europe to the possibility of gas warfare. In Britain, more than 50 million “antigas” helmets had been distributed by the beginning of World War II.

Questions of efficacy aside, Spiers writes that a combination of other factors averted the use
of chemical weapons during the Second World War. Because of the industrial and economic
hardships engendered as a result of the First World War, German, French, and British
chemical production capacity was limited. Hitler personally disdained chemical weapons,
which had injured him during World War I

Moreover, early in World War II, Germany did not need to resort to chemical weapons, and the Allies could not risk using them near friendlycivilian populations. Eventually, Germany did test its V1 and V2 rockets with chemical warheads, although the nation was deterred from using them by fear of reprisal against its civilian population. 

By the end of the war, U.S. military-industrial might had produced the world’s largest stock of chemical weapons and the air power to deliver them. However, the development of the atomic bomb, and success on other fronts, made their use unnecessary.

Biological weapons were not used to a significant extent in either the First or Second World
Wars. Nonetheless, as Spiers describes, there were still chilling reminders of the potential
power of even crude biological weapons. After the Japanese surrender in 1945, six Japanese soldiers released hordes of plague-infested rats and 60 horses infected with glanders into the Chinese countryside, leaving Changchun and surrounding environs uninhabitable until the mid-1950s.

Nuclear weapons, of course, came to dominate deterrence strategies during the Cold War.
Nonetheless, the proliferation of a new class of chemical weapons, nerve agents such as
sarin [2-(fluoro-methylphosphoryl)oxypropane], touched off a new chemical arms race, Spiers writes. From 1954 to 1969, the U.S. also manufactured and stockpiled numerous antiplant and antipersonnel biological weapons.

In Vietnam, the U.S. faced criticism, both at home and abroad, for its use of riot-control agents (to clear tunnels, for example), defoliants, and chemical weapons to kill crops and render soils infertile. In 1967 alone, the U.S. defoliated 1.5 million acres of vegetation and destroyed 220,000 acres of crops in Vietnam. In 1969, the Nixon Administration announced the end of the U.S. biological weapons program, in part, Spiers argues, to blunt criticism for its use of herbicides and riot control agents in Vietnam.

In the meantime, Spiers writes, the Soviets were developing the world’s most advanced chemical and biological weapons program.

During the Cold War, Iran and Iraq also waged a devastating war (1980–88) that again witnessed the mass by former Iraqi president Saddam Hussein.

Iraq estimated these attacks resulted in more than 30,000 Iranian casualties (compared with the 500,000 to 1 million estimated total Iranian casualties). As Spiers notes, although the number of casualties from chemical weapons may have been small on a relative basis, the psychological impact was significant. Iraq’s ballistic missiles, and the fear of their potential to deliver chemical warheads to Iranian cities, played a role in Iran’s accepting the United Nations-brokered truce in 1988. Iraqi chemical weapons also helped to suppress the internal Kurdish rebellion, killing and injuring thousands of Kurds and leading to the flight of 65,000 others to Turkey in 1988, Spiers writes.

By the 1990 invasion of Kuwait, Iraq had significantly restocked and improved its chemical weapons capabilities. U.S. Central Commander Gen. H. Norman Schwarzkopf originally planned for 10,000 to 20,000 chemical weapons casualties, but Iraq never resorted to chemical weapons. The George H. W. Bush Administration had already decided not to respond with nuclear or chemical weapons if coalition forces were attacked with chemical weapons, but they deliberately conveyed the opposite impression.

Iraqi Ambassador to the U.S. Tariq Aziz later commented that the Iraqis understood that the use of chemical weapons might very well provoke the use of nuclear weapons against Baghdad by the U.S. Although Iraq’s SCUD missile attacks against Israel, Saudi Arabia, and Bahrain inflicted minimal physical damage, the specter of chemical warheads inflicted great psychological damage. Spiers quotes Schwarzkopf: “The biggest concern was a chemical warhead threat. … Each time they launched … the question was, is this going to be a chemical missile. That was what you were concerned about.” 

Their unique ability to engender such fears, of course, is precisely what makes chemical and biological weapons appealing to terrorists. As Spiers astutely notes, “terrorists can choose when, where, and how to attack their targets, they can avoid many of the uncertainties that have bedeviled the military use of chemical and biological weapons. By maximizing the element of surprise, they can attack targets with low or non-existent levels of protection; by careful choice of target environment, especially an enclosed facility, they need not wait upon optimum meteorological conditions; by attacking highly vulnerable areas, they may use a less than optimal mode of delivery; and by making a chemical or biological assault, they may expect to capture media attention and cause widespread panic.”

Although chemical weapons have been used much more frequently, Spiers notes that on a per-mass basis, biological weapons are more lethal than chemical weapons. As advances in production technologies can simultaneously result in increased yields in smaller, harder-todetect facilities, the potential utility of biological weapons to terrorists will become even more significant. 


In the most well-known example of biological terrorism to date, in October 2001, just after the 9/11 attacks, anthrax-tainted letters began appearing in the U.S. Despite fears of another international attack, the strain was identified as having come from a domestic source, the Army research facility at Fort Detrick, Md. Letters were received in Florida, New York, Connecticut, and Washington, D.C., including a Senate office building. As Spiers described it, “massive panic and chaos” erupted, and Congress and the Supreme Court were closed for several days, although only 22 cases of anthrax actually resulted, including just five fatalities.


One of the most sobering developments outlined in the book is the application and
proliferation of emergent molecular biology techniques to the production of biological
weapons. Through the use of genetic engineering, new or modified organisms of greater
virulence, antibiotic resistance, and environmental stability may be produced. 

In one notable example foreshadowing the utility of biotechnology to weapons production, the Soviets developed the host bacterium Yersinia pseudotuberculosis, which through genetic engineering could also produce the myelin toxin. Infected animals developed both the tuberculosis-like symptoms caused by the bacteria and the paralysis induced by the myelin toxin. One former Soviet scientist recalled that after a briefing on the results, “the room was absolutely silent. We all recognized the implications of what the scientists had achieved. A new class of weapon had been found.”

Additional topics in this comprehensive book include the various international attempts at chemical and biological weapons disarmament, deterrence, and nonproliferation, including the 1993 Chemical Weapons Convention; the sarin attacks on the Japanese subways in the mid-1990s; the use of chemical warfare in developing-world conflicts; and the embarrassing failures of American and British intelligence regarding Iraqi chemical weapons that led to the second Gulf War. 

For those of us interested in the potential impacts of chemistry and biology on humankind, Spiers’s book is a thoroughly documented, no-nonsense (often to the point of being dry) review of the malevolent potential of our science.
