A once-secret CIA history of the Bay of Pigs invasion lays out in unvarnished detail how the American spy agency came to the rescue of and cut deals with authoritarian governments in Central America, largely to hide the U.S. role in organizing and controlling the hapless Cuban exile invasion force. The most powerful people in Central American embassies were the CIA station chiefs. Ambassadors step aside and allow the CIA to negotiate deals for covert paramilitary bases in a newly released portion of the CIA's Official History of the Bay of Pigs Operation." "What you're reading in this report shows again that in the hypocritical name of democracy the United States and CIA were willing to prop up some of the most cut-throat dictatorships," says researcher Peter Kornbluh of the National Security Archive at George Washington University. He sued the CIA for release of the Top Secret document that dissects one of the agency's greatest failures. Using secret interviews, cables and memos, CIA historian Jack B. Pfeiffer wrote the classified account of the disastrous operation to topple Fidel Castro. It's unusually candid because nobody except spies were expected read it. Both the Eisenhower and Kennedy governments wanted to be able to deny responsibility for the invasion.
