Protocol 60 details the first meeting of the Communist Party during the crisis. As Khrushchev is awaiting the announcement by President Kennedy of the discovery of missiles in Cuba, he and some of his colleagues briefly considered using tactical nuclear weapons in the event of a US airborne assault. But, at the suggestion of Soviet defense minister Rodion Malinovsky, the Kremlin postponed its consideration of a nuclear response pending details of Kennedy’s speech.The Kremlin wasted no time in taking steps to reduce the risks of confrontation. It ordered some ships that were still in the Mediterranean to turn around. The Aleksandrovsk, the ship carrying the nuclear warheads for the IRBMs (the R-14s), was ordered to keep sailing, however, because it was close enough to Cuban shores to dock before the blockade went into effect.

Protocol 39 gives some evidence that Khrushchev was thinking about more than just Cuba. Khrushchev discussed the importance of getting the US to stop flying over the ships heading to Cuba. After discussing the timetable for sending the missiles to Cuba, Khrushchev led his colleagues in a re-examination of the Soviet Union’s policy on West Berlin. Berlin had not been a topic of discussion for months.
