The U.S. President and nearly all his critics agree that the spread of nuclear weapons and the possibility of their seizure and potential use is the greatest danger facing the United States and the world. Looking at the way government and industry officials downplay the risks of civilian nuclear technology and materials being diverted to make bombs, one would get almost the opposite impression.

Most governments have made the promotion of nuclear power’s growth and global development a top priority. Throughout, they have insisted that the dangers of nuclear weapons proliferation are manageable either by making future nuclear plants more proliferation-resistant or by strengthening International Atomic Energy Agency safeguards and acquiring more timely intelligence on proliferators. How sound is this view? How useful might civilian nuclear programs be for states that want to get nuclear weapons quickly? Are current International Atomic Energy Agency nuclear safeguards sufficient to block military nuclear diversions from civilian programs? Are there easy fixes to upgrade these controls? How much can we count on more timely intelligence on proliferators to stem the further spread of nuclear weapons?

This volume taps the insights and analyses of 13 top security and nuclear experts to get the answers. What emerges is a comprehensive counternarrative to the prevailing wisdom, and a series of innovative reforms to tighten existing nuclear nonproliferation controls.
