The Vietnam War (1 November 1955 – 30 April 1975) was one of the most consequential conflicts of the Cold War era. Fought between North Vietnam and the Viet Cong, supported by the Soviet Union and China, against South Vietnam and its allies, primarily the United States, the war combined conventional battles with prolonged guerrilla warfare. From the jungles of Southeast Asia to the streets of Washington, the conflict reshaped military strategy, global politics, and public opinion. The fall of Saigon in 1975 marked not only the end of the war, but a turning point in American foreign policy and the wider Cold War struggle. Presented by War Lens History, this documentary explores the origins of the Vietnam War, major military phases, guerrilla tactics, civilian impact, anti-war movements, and the lasting legacy that continues to influence world politics today.
