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.

Secretary of State Dean Rusk tells Brazilian officials about letters that have been sent between Kennedy and Khrushchev discussing missile bases in both Cuba and Turkey.

Pinto describes a meeting with Roa in which Roa repeats a message from Fidel Castro's proclamation that the evacuation of the American base Guantanamo should be directed at not only the United States, but also the Soviet Union, to show both that Cuba is not a toy of the great powers and should be heard in the coming negotiations.

Suggestion for a decision to internationalize the Cuban crisis would permit Cuba and the Soviet Union to "save face", diminishing the dangerous possibility of direct confrontation.
