The United States government provided support to several Cuban exiles after the Cuban Revolution in 1959 , especially under the administration of George H. W. Bush . Among the most prominent of these were Orlando Bosch and Luis Posada Carriles , who were implicated in the 1976 bombing of a Cuban plane . Bosch was also held to be responsible for 30 other terrorist acts , while Carriles was a former CIA agent convicted of numerous terrorist acts committed while he was linked to the agency . Other Cuban exiles involved in terrorist acts , Jose Dionisio Suarez and Virgilio Paz Romero , two other Cuban exiles who assassinated the Chilean diplomat Orlando Letelier in Washington in 1976 , were also released by the administration of George H.W. Bush
