"A must read for anyone concerned with the risks of nuclear proliferation, biological and chemical threats, and how to counter them." —General Wesley K. Clark, U.S. Army (Ret.)|"This valuable book delivers more than what the title might suggest, as the scope of the book extends well beyond a narrow assessment of U.S. nuclear policy to a broader assessment of how that approach affects the nuclear nonproliferation regime and the overall state of the regime itself." —Barclay Ward, Arms Control Today, 3/1/2007|"a coherent, well-argued volume on nuclear policy...recommended." — CHOICE, 5/1/2007|"Help: We need to think clearly and urgently about the nuclear threat. This book offers valuable focus on the issue." —George Shultz, Hoover Institution and former U.S. Secretary of State|"A superbly comprehensive assessment of present and future U.S. nuclear weapons policy in the age of terrorism, this book updates thinking in a critical area of national security strategy." —Major General William F. Burns, U.S. Army (Ret.) and former director of U.S. Arms Control and Disarmament Agency|"Remarkable for the authors' breadth and depth of experience, the timeliness and importance of the subject, and the willingness to provide near-term solutions that neither revere nor reject the past. An authoritative, insightful, and constructive book." —Richard L. Garwin, IBM Research Center, and member of the President's Science Advisory Committee|"Anyone concerned about the gravest danger humanity faces ought to read this book. Written and edited by some of the most thoughtful and experienced people in the field, it vividly describes our present predicaments and offers alternatives, backed by solid analysis, to current administration nuclear weapons policies." —James E. Goodby, Carnegie Mellon University and former chief negotiator, U.S. Cooperative Threat Reduction Program
