"The shocking story of how America became one of the world's safest postwar havens for Nazis. Until recently, historians believed America gave asylum only to key Nazi scientists after World War II, along with some less famous perpetrators who managed to sneak in and who eventually were exposed by Nazi hunters. But the truth is much worse, and has been covered up for decades: the CIA and FBI brought thousands of perpetrators to America as possible assets against their new Cold War enemies.
