USA HISTORY

Detailed explanation-1: -While the Kennedy administration planned Operation Mongoose, Soviet Premier Nikita Khrushchev secretly introduced medium-range nuclear missiles into Cuba.

Detailed explanation-2: -Nikita Sergeyevich Khrushchev (15 April [O.S. 3 April] 1894 – 11 September 1971) was the First Secretary of the Communist Party of the Soviet Union from 1953 to 1964 and chairman of the country’s Council of Ministers from 1958 to 1964.

Detailed explanation-3: -The US government distrusted Castro and was wary of his relationship with Nikita Khrushchev, the leader of the Soviet Union.

Detailed explanation-4: -Another key factor in the Soviet missile scheme was the hostile relationship between the U.S. and Cuba. The Kennedy administration had already launched one attack on the island–the failed Bay of Pigs invasion in 1961–and Castro and Khrushchev saw the missiles as a means of deterring further U.S. aggression.
