The answer is Vietnamization. President Richard Nixon in 1969 presented a new approach named Vietnamization that was intended at ending American participation in the Vietnam War by transferring all military accountabilities to South Vietnam. The gradually unpopular war had created deep divisions in American society. Nixon assumed his Vietnamization strategy, which involved building up South Vietnam’s military strength in order to facilitate a gradual withdrawal of U.S. troops, would help get ready the South Vietnamese to take charge for their own defense against a Communist takeover and allow the U.S. to leave the conflict with its honor intact. In 1973, the U.S. negotiated a treaty with the North Vietnamese, withdrew American combat troops and declared the Vietnamization process complete. However, in 1975, South Vietnam fell to Communist forces.
