"Blowback is the fullest and most authoritative account ever written of America's collaboration with Nazi after World War II, and of the long-range effect this has had on the nation's domestic and foreign policy. Drawing on extensive firsthand research and a wealth of documents previously classified or never before made public, Christopher Simpson has written a major and often startling work about the extensive connection between high-ranking American officials and ex-Nazis and collaborators, and about the effect this relationship has had on American society and the cold war."--Book Jacket.
