foreword by William S. Cohen, U.S. Secretary of Defense Biological weapons pose a horrifying and growing threat to the United States and to the world in general. Revelations about Iraq's weapons research and the plans of the Aum Shinrikyo cult in Japan serve as frightening reminders of the potential for military or terrorist use of biological agents. The essays in this book, many of which were originally published in the Journal of the American Medical Association, examine the medical, scientific, and political dimensions of limiting the threat posed by biological weapons. The contributors consider the current threat posed by biological weapons, the history of attempts to control them, episodes in which biological agents have been used, Iraq's biological warfare program, and policies that the United States might pursue to reduce the threat.
