Who was the US president during the Vietnam War and the Cuban Missile Crisis, and was later assassinated?

John F. Kennedy served as the President of the United States during the early years of the Vietnam War and was a key figure during the Cuban Missile Crisis in October 1962. His administration faced significant challenges in foreign policy, specifically as tensions escalated with the Soviet Union and in Southeast Asia. Kennedy's involvement in escalating U.S. military presence in Vietnam marked the beginning of deep American involvement in the conflict, while his handling of the Cuban Missile Crisis demonstrated his commitment to confronting Soviet aggression. Tragically, he was assassinated in November 1963, a pivotal moment in American history that left a lasting impact on the nation and its politics. His leadership style and decisions during these significant events continue to be studied and debated in the context of the Cold War and U.S. foreign intervention.

In contrast, the other presidents listed were not in office during both of these significant events. Ronald Reagan served later, primarily in the 1980s, while Lyndon B. Johnson succeeded Kennedy and escalated the Vietnam War after Kennedy's assassination. Richard Nixon is known for his role in concluding U.S. involvement in Vietnam but was not president during the Cuban Missile Crisis.
