What led President John F. Kennedy to blame Soviet premier Nikita Khrushchev for causing a threat to world peace?

The deployment of Soviet missiles on Cuba led to a stand off between the USA and Soviet Union. It was the closest the superpowers came to nuclear war.

Initially Khrushchev refused to back down as Kennedy imposed a naval blockade. However the Soviet leader eventually did back down. Kennedy emerged with an enhanced reputation after a series of failures both international and domestic, for example The Bay of Pigs fiasco. Khrushchev was removed from power and replaced by Leonard Brezhnev.

President John F. Kennedy blamed Soviet Premier Nikita Khrushchev for causing a threat to world peace primarily due to the Cuban Missile Crisis of October 1962. During this crisis, the United States discovered that the Soviet Union was secretly installing nuclear missiles in Cuba, which posed a direct threat to the security of the United States and its allies. Kennedy publicly accused Khrushchev of escalating tensions by deploying these missiles, which brought the world to the brink of nuclear war. Kennedy's administration held Khrushchev responsible for the crisis, arguing that his actions endangered global stability and violated international norms.
