Protocol 59 further details the focus of the Soviet Union just before the Cuban Missile Crisis. Khrushchev was so confident that his plan with Cuba would go unhindered that he spent his efforts on resolving the Sino-Indian border conflict, thinking the matter with missiles was done.

Protocol 58 provides insight into what was occupying the mind of Khrushchev at the time of the Cuban Missile Crisis. The theme of the meeting was centered around the Sino-Indian conflict, questions surrounding the McMahon line, and the future of Tibet. With the focus on China and India, it is reasonable to assume that the crisis caught Khrushchev by surprise.

The telegram bears on the circumstances surrounding Fidel Castro's controversial 27 October letter to Khrushchev. Alekseev describes Castro's demeanor as being irritated and paranoid at the time of writing the letter. He provides background on Castro's actions and attitudes at the peak of the crisis, and especially his nocturnal visit to the Soviet embassy and preparation of his letter to Khrushchev on the night of 26-27 October. He advises Moscow on how to handle the Cuban leader, and offers analysis into the emotions and overall mood of Castro and his associates at that moment in the crisis.
