On April 12, 1962, General Landsdale forwarded to Maxwell Taylor and "advance copy" of the Joint Chiefs' paper on "Pretext," stating "I am informed that the Chiefs approved this." The paper, captioned "Justification for U.S. Military Intervention in Cuba (TS)," set forth 9 "pretexts."
These include:
"We could develop a Communist Cuban terror campaign in the Miami area, in other Florida cities and even in Washington. The terror campaign could be pointed at Cuban refugees seeking haven in the United States. We could sink a boatload of Cubans enroute to Florida (real or simulated). We could foster attempts on lives of Cuban refugees in the United States even to the extent of wound in instances to widely publicized. Exploding a few plastic bombs in carefully chosen spots, the arrest of a Cuban agent and the release of prepared documents substantiating Cuban involvement also would be helpful in projecting the idea of an irresponsible goverment."
The memerandum contains a disjointed list of ideas, including: "Assassinate Castro and his handful of top men."
"The objective of the MONGOOSE program is to cause the visible failure of the target regime as quickly as possible as a preliminary to its ultimate elimination. In pursuing this objective the U.S. will make maximum use of indigenous and non-U.S. personnel and resources, particularly of covert operations.
"The current intelligence collection program will continue essentially as at present. Increased efforts will be directed at weakening the economy of the target country, to include a stepped-up program of economic sabotage. An intensive propaganda campaign will be maintained, designed to do maximum damage to the image of the target leader as a succesful liberating revolutionary, while stressing the failures of his regime.
