Why the US became increasingly involved in the war in Vietnam. Extracts from this document... Introduction. Why the US became increasingly involved in the war in Vietnam America became increasingly involved in the war in Vietnam, mainly because of the domino theory, the fear of the spread of communism.
The Vietnam War was fought between communist North Vietnam and the government of Southern Vietnam. The North was supported by communist countries such as the People's Republic of China and the Soviet Union. The South was supported by anti-communist countries, primarily the United States. The United States lost the Vietnam War. It lasted for twenty years, something the US never expected when it joined in the fight.
