Definition of Vietnam War in US English:

Vietnam War

proper noun

  • A war between Communist North Vietnam and US-backed South Vietnam.

After the partition of Vietnam in 1954, the communist North attempted to unite the country as a communist state, fueling US concern over the possible spread of communism in Southeast Asia. US Army forces were sent to Vietnam in 1964, supported by contingents from South Korea, Australia, New Zealand, and Thailand, while US aircraft bombed North Vietnamese forces and areas of Cambodia. The Tet Offensive of 1968 damaged US confidence, and US forces began to be withdrawn, finally leaving in 1973. The North Vietnamese captured the southern capital Saigon to end the war in 1975
