Calderio's visit to Prague in the aftermath of the Cuban Missile Crisis served to solidify the ties between Cuba and Czechoslovakia, relations that would persist until the end of the Cold War. Among the activities of Calderio's visit included attendance of 12th Party Congress of the Czechoslovak Communist Party, meeting with Cuban ambassadors to China, Czechoslovakia and Hungary, and a promise to attend the meeting of the Bulgarian Communist Party.

The report to Novotny details the happenings of the Cuban Missile Crisis at that time. Great Britain feels out of the loop and hurt by not being consulted by the United States before it took action, while Kennedy is not backing down on the blockade until the missiles are removed. According to the message, it is unclear whether there are nuclear missiles in Cuba at all; an American army colonel admits to the UN that no traces have been found, despite hundreds of photographs taken. In Czechoslovakia, the situation is unchanged; troops are still on alert and awaiting combat orders, with morale running high. There are even some volunteers willing to go to Cuba and aid their Latin comrades.

This concerns the status of Czechoslovak domestic organizations at the time of the Cuban Missile Crisis. Included in the report are the Revolutionary Trade Union Movement, Central Council of Labor Unions, Czechoslovak Union of Youth, and the National Front.

This report to Antonin Novotny details the European military situation at the time of the Cuban Missile Crisis. Most NATO troops were on combat alert, but no increased activity or suspicious movements were reported. The Czechoslovak Armed Forces were at combat ready status to repel any attack by NATO.
