The fear of a nuclear war existed in the world under JFK’s presidency in the United States. However he was also the reason the world was saved from such a threat. Both the United States and Cuba were ready to use nuclear weapons in battlefield. The arms race exaggerated the access of the nuclear weapons both in the U.S. and the Soviet Union. Khruschev’s plan to place missiles in Cuba, directing at the U.S. initiated circumstances that led to the Cuban Missile Crisis. What seems to have relieved the conflict from both sides was the constant communication between the two countries. The back and forth dialogue between Khrushchev and Kennedy via letters, helped to come to an agreement to dismantle nuclear weapons in Cuba and bring them back to the Soviet Union if the U.S. promised to not invade Cuba. Later it was also suggested by Khrushchev that the U.S. also dismantle their missiles in Turkey.
