When did the US pull out of the Vietnam War? Some sources say 1973 and then others say 1969..?
The last U.S. combat troops left Vietnam on March 29, 1973.

The confusion regarding the withdrawal of the US from the Vietnam War stems from the fact that there were actually two significant events related to the withdrawal.
1. In 1969, President Richard Nixon announced the "Vietnamization" policy, which aimed to gradually shift the burden of fighting the war from American troops to South Vietnamese forces. As part of this strategy, Nixon ordered a gradual reduction in the number of US troops in Vietnam. By the end of 1971, the American troop presence had significantly decreased.
2. The final withdrawal of US combat troops from Vietnam occurred in 1973, after the signing of the Paris Peace Accords. These accords were an agreement between the US, South Vietnam, North Vietnam, and the Viet Cong to end the war. Under the terms of the agreement, all US combat troops were withdrawn from Vietnamese territory.
So, both years, 1969 and 1973, are correct but signify different milestones in the US withdrawal from the Vietnam War. The gradual reduction of troops began in 1969, but it was not until 1973 that the last combat troops were officially withdrawn.
