One major political change that occurred during the 1960’s was Kennedy’s quarantining of Cuba. In 1962 American spy planes figured out that the Soviets were installing missiles in cuba, which could reach the United States. Kennedy determined that the missiles were intolerable and had to act upon this threat immediately. Kennedy decided to blockade Cuba, and demanded that the missiles be removed. Khrushchev, of the Soviet Union, agreed to withdraw the missiles, and America said that they would not invade Cuba. This was known as the Cuban Missile Crisis.
This series of events stems from the “massive retaliation” of the 1950’s. In 1952 the US exploded the first hydrogen bomb. This was the most deadly bomb yet. The Soviets retaliated and created their own bomb. What resulted was that both sides now had weapons of mass destruction that could potentially harm a big chunk of the world. This began “massive retaliation,” or the idea that the US would attack the Soviets if the Soviets were ever to attack them. While none of this actually occurred, it did create an even bigger competition between the US and Soviet Union, and it make both sides very paranoid of the other’s weapons. This is why the Cuban Missile Crisis occurred during the 1960’s.
Below is a video showing Kennedy’s reaction to the discovery of Soviet missiles. These missiles were only created because of US hydrogen bomb, the Cold War, and massive retaliation, which all took place in the 1950’s.
