There were five United States presidents who held office during the Vietnam War. These five presidents were Dwight Eisenhower, John F. Kennedy, Lyndon Johnson, Richard Nixon and Gerald Ford.
Eisenhower began the United States' involvement with the Vietnam War by creating the Southeast Asia Treaty Organization to help squelch communist uprisings in the area. Kennedy wished to overthrow Prime Minister Ngo Sinh Diem, the leader of Vietnam, but was assassinated before he could do so. The first combat troops were sent to Vietnam under Johnson's term as president. During Nixon's presidency, the Paris Peace Accords were signed. However, the war did not officially end until April 23, 1975, under Ford's presidency.
