What was one of the significant events during John F. Kennedy's presidency?

The Cuban Missile Crisis was indeed a significant event during John F. Kennedy's presidency and is often cited as one of the most critical moments of the Cold War. It occurred in October 1962 and involved a tense 13-day standoff between the United States and the Soviet Union. The crisis was triggered by the discovery of Soviet nuclear missiles stationed in Cuba, just 90 miles from the U.S. mainland. Kennedy's administration faced the immediate threat of nuclear war, prompting careful deliberation on how to respond.

Kennedy chose to pursue a naval blockade (referred to as a "quarantine") to prevent further Soviet shipments of military equipment to Cuba while simultaneously engaging in diplomatic negotiations. The successful resolution of the crisis, which involved the Soviets agreeing to remove their missiles in exchange for U.S. assurances not to invade Cuba and the secret removal of U.S. missiles from Turkey, showcased Kennedy's leadership during a moment of immense international tension. This event had a lasting impact on U.S.-Cuba relations and shaped Cold War dynamics moving forward.
