Summary and Keywords
From 1965 to 1973, the United States attempted to prevent the absorption of the non-Communist state of South Vietnam by Communist North Vietnam as part of its Cold War strategy of containment. In doing so, the United States had to battle both the North Vietnamese military and guerrillas indigenous to South Vietnam. The Johnson administration entered the war without a well-thought-out strategy for victory, and the United States quickly became bogged down in a bloody stalemate. A major Communist assault in 1968 known as the Tet Offensive convinced US leaders of the need to seek a negotiated solution. This task fell to the Nixon administration, which carried on peace talks while simultaneously seeking ways to escalate the conflict and force North Vietnam to make concessions. Eventually it was Washington that made major concessions, allowing North Vietnam to keep its forces in the South and leaving South Vietnam in an untenable position. US troops left in 1973 and Hanoi successfully invaded the South in 1975. The two Vietnams were formally unified in 1976.
The war devastated much of Vietnam and came at a huge cost to the United States in terms of lives, resources, and political division at home. It gave birth to the largest mass movement against a war in US history, motivated by opposition both to conscription and to the damage that protesters perceived the war was doing to the United States. It also raised persistent questions about the wisdom of both military intervention and nation-building as tools of US foreign policy. The war has remained a touchstone for national debate and partisan division even as the United States and Vietnam moved to normalize diplomatic relations with the end of the Cold War.
