In conversation with a high officials from the State Department about the prospects of the Cuban situation, three hypotheses about the future Soviet comportment are discussed: 1) abandon entirely the government of Fidel Castro to its own fate; 2) limit itself to leave constituted in Cuba a socialist regime, based on a well-structured communist party and endowed with a repressive political machine, as a political base of propaganda and infiltration in Latin America and 3) to intensify Soviet technical and economic assistance in a manner to transform Cuba into a living demonstration of the efficacy of communism as an instrument of economic development in Latin America. The letter goes on to describe these three points in more detail.
