Vietnam War

The Vietnam War was a war fought between and Northern and Southern Vietnam, with the North being pro-communism and the south being anti-communist. Naturally, the US felt obligated to stop the spread of communism, and decided to provide support to Southern Vietnam. America suffered huge losses (58,000), and the idea that so many lives were lost/ being lost in a war that wasn't really directly related to them led to division among the American people. President Nixon ordered the withdrawal of all American troops in 1973. The communists forces then captured Saigon, marking the end of the Vietnam war. The following year, 1976, the country united as the Socialist Republic of China
