The Bulgarian Embassy in Havana reports to the Central Committee of the Bulgarian Communist Party and the Bulgarian Ministry of Foreign Affairs on political, economic, and cultural developments in Cuba circa 1963. Cuba is politically united, but is experiencing economic hardship after the “Caribbean Crisis” primarily because of the US embargo. In the report, embassy staff reviews developments between socialist countries and Cuba throughout 1963. Some examples include communist aid to Cuba after Hurricane Flora and Cuba’s stance on Sino-Soviet relations. Bulgaria’s show of solidarity resulted in concrete political, economic, and cultural cooperation. Embassy staff notes the drawbacks and benefits of Bulgaria’s relationship with Cuba.

Drozniak forwards a report from US Assistant Secretary of State for Inter-American Affairs [Edwin M.] Martin. Martin says that the Americans are well-informed of the military situation in Cuba, that Cuba does not possess nuclear weapons (nor will they be likely to because the USSR did not give such weapons to China, so why would they give them to Cuba?), that the level of the Cuban economy is twenty-five percent lower than the period before Fidel Castro came to power and Cuba is much more economically dependent on the USSR, and finally that any military invasion or complete blockade of Cuba would be considered an act of war by the USSR.
