Often described as the misuse of science, chemical and biological weapons have incurred widespread opposition over the years. Despite condemnation from the United Nations, governments, and the disarmament lobby, they remain very real options for rogue states and terrorists. In this new edition of Agents of War, Edward M. Spiers has expanded and updated this much-needed history with two new chapters on political poisoning and chemical weapons in the Middle East. Spiers breaks new ground by presenting his analysis in both historical and contemporary contexts, giving a comprehensive chronological account of why, where, and when such weapons were used or suspected to be deployed.

Edward M. Spiers is professor emeritus at the University of Leeds. He is the author of nineteen books, including Chemical Warfare and Weapons of Mass Destruction: Prospects for Proliferation.
