What happened
Cold War containment drew the United States into a long war in Vietnam. After reported attacks on U.S. destroyers, Congress passed the Gulf of Tonkin Resolution on August 7, 1964, authorizing the president to take all necessary measures, and the Johnson administration escalated to hundreds of thousands of American troops. The war ground on for years without victory, and opposition grew at home. Protests spread across campuses and cities, and the shooting deaths of four students at Kent State University on May 4, 1970, became a symbol of the divide. A peace agreement was signed on January 27, 1973, and American forces withdrew, but the war ended only when North Vietnamese tanks rolled into Saigon on April 30, 1975. The National Archives records 58,220 U.S. military fatal casualties of the war.
Why it matters
Vietnam shattered public trust in the government and the military and left a lasting caution about foreign wars that shaped American politics for decades. The gap between official optimism and battlefield reality, the credibility gap, and the bitter divisions over the draft and the protests marked a generation and changed how Americans view their leaders and their wars.
How we know
The Gulf of Tonkin Resolution and the war's casualty statistics survive in the National Archives, and the escalation, protests, peace agreement, and fall of Saigon are documented in State Department histories and an extensive contemporary and archival record.
