In what year were the majority of American troops pulled out of Vietnam?

The majority of American troops were pulled out of Vietnam in 1973 as a result of the Paris Peace Accords, which were signed in January of that year. This treaty aimed to establish peace and effectively end the United States' direct military involvement in Vietnam, allowing for a withdrawal of U.S. forces. By the end of that year, most American combat troops had returned home, aligning with the significant de-escalation strategy adopted by the Nixon administration. The other years mentioned reflect different stages of U.S. involvement in the Vietnam War, with significant troop deployments occurring before 1973, leading to a drawdown that culminated in the established timeline of withdrawals.
