Marxism–Leninism Cuban Revolution, led by Fidel Castro and Ché Guevara, overthrew the régime (1925–1959) of Fulgencio Batista to establish the Republic of Cuba, a Communist state recognised by the Soviet Union. In response, the United States attempted a coup d'état against the Castro government, such as the unsuccessful Bay of Pigs invasion (April 1961), by anti-communist Cuban exiles, sponsored by the CIA. The next year, there occurred the Cuban missile crisis (October 1962), a diplomatic dispute between the United States and the Soviet Union over the presence of medium-range, Soviet nuclear missiles in Cuba. The Soviet Union resolved the nuclear-missile crisis
CIA cryptonym plan concerned Cuba. Occasionally the special code names come close to the nerve, as did MONGOOSE." A secret joint program between the Mexico City CIA station and the Mexican secret police to wiretap the Soviet and Cuban embassies was code-named ENVOY. Some cryptonyms relate to more than one subject, e.g., a group of people. In this case, the basic cryptonym, e.g., LICOZY, will designate the whole group, while each group member is designated by a sequence number, e.g., LICOZY/3, which can also be written LICOZY-3, or just L-3.
