Fidel Castro, after his first contacts with Brazilian President João Goulart’s special envoy Albino Silva, accepted well the Brazilian thesis which contains following: Denuclearization of the whole of Latin America and the embargo on atomic weapons delivery; Inspection by UN; Cuba would commit neither to export revolution nor to carry out any subversive activities; Cuba would be given guarantees for keeping its sovereignty and independence. The USA will accept the plan after negotiations. Russians “couldn’t think of anything better.”

A telegram from the Yugoslav Embassy in Rio de Janeiro to the Yugoslav Foreign Ministry discussing the Cuban Missile Crisis and U.S.-USSR-Cuban relations. It says, the "American arguments in favor of the military blockade of Cuba are: firstly, they have solid proof that Cuba will get atomic weapons; secondly, Kennedy must take more severe measures because of the internal pressure, that’s why his option is blockade, although he is trying to transfer this issue to the UNO [United Nations Organization] in order to alleviate the pressure on himself; thirdly, transferring Cuba’s issue to the UNO he is creating a precedent against unilateral USSR actions in Berlin."

The tight secrecy continues to surround the conversations with Anastas Mikoyan, however in a conversation with Pinto, he reveals information concerning: Fidel Castro, Cuban-Soviet relations during the crisis and Cuba's refusal to submit to international inspections.

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.
