What is cuban missile crisis?

Cuban Missile Crisis Cuban Missile Crisis is a term that denotes the confrontation between the two superpowers i.e., the USA and the USSR.
The Soviet Union led by the Nikita Khrushchev installed nuclear missiles in Cuba in the hope of converting Cuba into a Russian base. The main aim was to plan a devastating attack on the USA if they start a war. This installation of nuclear missiles threatened a number of cities of the American mainland. It was because they were set on the target of those missiles. As a result, the US President, John F. Kennedy and his advisors ordered the American warships to intercept any Soviet ships heading to Cuba so as to avoid a full-scale nuclear war. At this step of the USA, Russian President ordered Warships to headed towards Cuba. This series of tensions and confrontation between the United States and the Soviet Union is known as the 'Cuban Missile Crisis' which later came to be known as an event of  'Cold War'.
Two world leaders who played a crucial role in the Cuban Missile Crisis were Nikita Khrushchev and John F Kennedy. This crisis could be avoided with the help of the UN.

It was a confrontation between the United States and the Soviet Union in 1962 over the presence of missile sites in Cuba; one of the “hottest” periods of the cold war.
