when did the united states withdrew from vietnam
Vietnam War Vietnamization was again tested by the Easter Offensive of 1972, a massive conventional NVA invasion of South Vietnam. The NVA and Viet Cong quickly overran the northern provinces and in coordination with other forces attacked from Cambodia, threatening to cut the country in half. U.S. troop withdrawals continued. American airpower responded, beginning Operation Linebacker, and the offensive was halted. However, it became clear that without American airpower South Vietnam could not survive. The last remaining American ground troops were withdrawn by the end of March 1973; U.S. naval and air forces remained in the Gulf of Tonkin, as well as Thailand and Guam.[255]
Vietnam War The Vietnam War (Vietnamese: Chiến tranh Việt Nam), also known as the Second Indochina War,[59] and also known in Vietnam as the Resistance War Against America (Vietnamese: Kháng chiến chống Mỹ) or simply the American War, was a conflict that occurred in Vietnam, Laos, and Cambodia from 1 November 1955[A 1] to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam. The North Vietnamese army was supported by the Soviet Union, China and other communist allies and the South Vietnamese army was supported by the United States, South Korea, Australia, Thailand and other anti-communist allies.[60] The war is therefore considered a Cold War-era proxy war.[61]
