In the first place, one the reasons why the Soviet Union placed missiles in Cuba was because they wanted to increase as a country their power since at that time the countries with superpower was the US and the Soviet Union. And, by placing these nuclear missiles it shows a menace of a nuclear attack to the
United States. Khrushchev was the one in charge of the order of the missiles in Cuba. Then, the US sent a spy plane which took photographs that Soviet missiles were being under construction. President Kennedy responded by declaring a quarantine against Cuba to avoid a nuclear war in October 22 of 1962 on Washington. The cause of this blockade made the Soviets suggested that they will get rid of the missiles in exchange that the US promise not to attack Cuba on October 26. Because of this suggestion the deployment of operations of Soviets missiles in Cuba moved away from the regular policies. The Soviet Union just like the US did not wanted to start a nuclear war that could cause major damages on both countries and had no other choice than withdraw the missiles. The events that strayed away from the original policy were caused by the Soviet Union that applied its theory to move the nuclear weapons into Cuba. Since, the Soviet Union and Cuba were powerful associates was one of the reasons why the Cuban government approved the Soviets missiles inside Cuba. Finally, on October 28th the Soviets began withdrawing their missiles from Cuba. The next day President Kennedy drop the blockade.
