In this important and revelatory book, Jonathan Tucker, a leading expert on chemical and biological weapons, chronicles the lethal history of chemical warfare from World War I to the present. At the turn of the twentieth century, the rise of synthetic chemistry made the large-scale use of toxic chemicals on the battlefield both feasible and cheap. Tucker explores the long debate over the military utility and morality of chemical warfare, from the first chlorine gas attack at Ypres in 1915 to Hitler’s reluctance to use nerve agents (he believed, incorrectly, that the U.S. could retaliate in kind) to Saddam Hussein’s gassing of his own people, and concludes with the emergent threat of chemical terrorism. Moving beyond history to the twenty-first century, War of Nerves makes clear that we are at a crossroads that could lead either to the further spread of these weapons or to their ultimate abolition.

Carried by a long-awaited wind, the chlorine cloud passed within a few minutes through the British and French trenches, leaving behind at least 1,000 dead and 4,000 injured. This chemical attack, which amounted to the first use of a weapon of mass destruction, marks a turning point in world history. The preparation as well as the execution of the gas attack was orchestrated by Fritz Haber, the director of the Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry in Berlin-Dahlem. During World War I, Haber transformed his research institute into a center for the development of chemical weapons (and of the means of protection against them). Bretislav Friedrich and Martin Wolf (Fritz Haber Institute of the Max Planck Society, the successor institution of Haber’s institute) together with Dieter Hoffmann, Jürgen Renn, and Florian Schmaltz (Max Planck Institute for the History of Science) organized an international symposium to commemorate the centenary of the infamous chemical attack. The symposium examined crucial facets of chemical warfare from the first research on and deployment of chemical weapons in WWI to the development and use of chemical warfare during the century hence. The focus was on scientific, ethical, legal, and political issues of chemical weapons research and deployment — including the issue of dual use — as well as the ongoing effort to control the possession of chemical weapons and to ultimately achieve their elimination. The volume consists of papers presented at the symposium and supplemented by additional articles that together cover key aspects of chemical warfare from 22 April 1915 until the summer of 2015.

The Chemical Weapons Convention is one of the cornerstone disarmament and arms control agreements, and the only global and comprehensive disarmament treaty that is being verified by an international agency. This Commentary assesses the provisions of the Convention and its implementation, with cross-cutting chapters providing a broader analysis.
