Finding DEF-2.10
Primary record A Joint Chiefs of Staff memorandum of 13 March 1962, forwarded to the Secretary of Defense as "a preliminary submission suitable only for planning purposes," listed pretexts for U.S. military intervention in Cuba, including "We could blow up a US ship in Guantanamo Bay and blame Cuba." Lansdale's memorandum for the record says the President said on 16 March 1962 that "we were not discussing the use of U.S. military force", and the cited records show no approval and no execution of any item.
