When did the United States leave the Vietnam War?

The correct answer is 1975, as this marks the official end of U.S. involvement in the Vietnam War. The U.S. began its withdrawal of combat troops in 1973, following the Paris Peace Accords, which aimed to establish peace in Vietnam and restore the country’s sovereignty. However, the conflict continued between North and South Vietnam until April 30, 1975, when North Vietnamese forces captured Saigon, leading to the unification of Vietnam under communist control. This event symbolized the definitive end of U.S. military engagement in Vietnam, making 1975 the date when the United States effectively left the war.
