The Vietnam War (1955–1975)

The Vietnam War was a prolonged and divisive Cold War conflict. It pitted the communist North Vietnam and its allies against South Vietnam and its primary supporter, the United States. The war's brutal guerrilla tactics, extensive use of televised news, and strong anti-war movements reshaped global politics and eroded public trust in government, leading to a profound shift in U.S. foreign policy and a reevaluation of military intervention.
