"Engrossing." — Wall Street Journal

A global history of U.S. nuclear espionage from its World War II origins to today's threats from rogue states. For fifty years, the United States has monitored friends and foes who seek to develop the ultimate weapon. Since 1952 the nuclear club has grown to at least eight nations, while others are making serious attempts to join. Each chapter chronologically focuses on the nuclear activities of one or more countries, intermingling what the United States believed was happening with accounts of what actually occurred in each country's laboratories, test sites, and decision-making councils. Jeffrey T. Richelson weaves recently declassified documents into his interviews with the scientists and spies involved in the nuclear espionage. The book reveals new information about U.S. intelligence work on the Soviet/Russian, French, Chinese, Indian, Israeli, and South African nuclear programs; on the attempts to solve the mysterious Vela Incident; and on current efforts to uncover the nuclear secrets of Iran and North Korea. The book also includes spy satellite photographs never before extracted from the national archives.

The updated paperback edition includes analysis of the diplomatic maneuvering and intelligence activities that have taken place over the last year in the continued attempt to halt Iran's quest for nuclear weapons. 46 photographs, 4 maps.
