At 1962 there was a biggest crisis between the two superpowers. In October American spy planes found out that the Soviet Union installed missiles in Cuba with nuclear weapons because U.S. installed missies on Turkey. The Cuban missiles were capable of reaching the United States which caused a great atmosphere of fear that the nuclear weapons would directly attack U.S., so it became the most difficulty for the Kennedy administration. President Kennedy rejected to attack Cuba instead of to block Cuba and demand that Soviet Union remove missiles from Cube. However, Kennedy started to negotiate with the Soviet Union’s premier Nikita Khrushchev. After thirteen days both of them agreed to withdraw missiles on Cuba and Turkey, also Kennedy promised that would not invade Cuba. Kennedy foreign police successfully ease the most dangerous crisis between the two superpowers in the cold war.
