History of the United States (1964–1980)
The growing Watergate scandal was a major disaster for Nixon, eroding his political support in public opinion and in Washington. However he did manage to secure large-scale funding for South Vietnam, much of which was wasted. The United States withdrew its troops from Vietnam before the Paris Peace Accords in 1973. However, Watergate resulted in significant Democrat gains in the 1974 midterm elections and when the new 94th Congress convened the following January, it immediately voted to terminate all aid to South Vietnam in addition to passing a bill forbidding all further US military intervention in Southeast Asia. President Ford was against this, but as Congress had a veto-proof majority, he was forced to accept. South Vietnam rapidly collapsed as the North invaded it in force, and Saigon fell to the NVA on April 30, 1975. Later nearly one million Vietnamese managed to flee to the U.S. as refugees. The impact on the U.S. was muted, with few political recriminations, but it did leave a "Vietnam Syndrome" that cautioned against further military interventions anywhere else. Nixon (and his next two successors Ford and Carter) had dropped the containment policy and were not willing to intervene anywhere.
Cold War (1962–1979)
The U.S. pulled its troops out of Vietnam in 1973, and the conflict finally ended in 1975 when the North Vietnamese took Saigon, now Ho Chi Minh City. The war exacted a huge human cost in terms of fatalities (see Vietnam War casualties). 195,000–430,000 South Vietnamese civilians died in the war. 50,000–65,000 North Vietnamese civilians died in the war. The Army of the Republic of Vietnam lost between 171,331 and 220,357 men during the war. The official US Department of Defense figure was 950,765 communist forces killed in Vietnam from 1965 to 1974. Defense Department officials concluded that these body-count figures need to be deflated by 30 percent. In addition, Guenter Lewy assumes that one-third of the reported "enemy" killed may have been civilians, concluding that the actual number of deaths of communist military forces was probably closer to 444,000. Between 200,000 and 300,000 Cambodians, about 35,000 Laotians, and 58,220 U.S. service members also died in the conflict.
