With tensions between the U.S. and Cuba approaching a zenith point, Fidel Castro took the opportunity and sought help from Khrushchev with some reinforcements.
Castro agreed to allow the shipment of Soviet missiles to the Cuba in 1962. Word about
nuclear warheads with striking distance of U.S. soil prompted a meeting with President Kennedy and his newly formed national security team (referred to as ExCom for Executive Committee of the National Security Council) to gather intelligence on the
Kennedy’s options were limited, especially after the Bay of Pigs disaster, but ultimately decided on a blockade of the Cuban coast. After Kennedy made the announcement to the American people, tensions between the U.S. and the Soviets reached an all-time high. Kennedy demanded the Soviets to remove the missiles off Cuba, but Khrushchev had demands of his own with both Castro and Soviet military in Cuba ready to strike if felt threatened by a possible U.S. attack.
From the next several days, negotiations between Kennedy and Khrushchev ensued as well as talks between the U.S. and the United Nations hoping a nuclear war could be averted. Khrushchev made a counter offer to Kennedy where he would remove the missiles from Cuba in exchange to agree never to invade Cuba and the removal missiles out of the NATO nation of Turkey. On October 28 after U.S. Soviet officials meet to hammer out final provisions, an agreement was made with missiles removed from both Cuba and Turkey, providing a buffer zone for both nations, but also averting nuclear war.
