Episode 24 of Turning Points: History’s Greatest Battles examines the Tet Offensive (1968) — the moment the Vietnam War shifted from a military contest to a crisis of confidence. Despite repeated assurances from U.S. leadership that victory was near, North Vietnamese and Viet Cong forces launched a massive, coordinated surprise attack during the Tet holiday, striking more than 100 cities, towns, and military bases across South Vietnam. Although the offensive was ultimately repelled and resulted in devastating losses for communist forces, its psychological impact was profound. Images of fighting in Saigon, including the breach of the U.S. Embassy, and weeks of brutal urban combat in Hue shattered public belief in official claims of progress. Tet revealed a critical truth of modern warfare: military success does not guarantee political victory. Media coverage brought the war directly into American homes, eroding public support and trust in government. In the aftermath, President Lyndon B. Johnson declined to seek re-election, peace talks began, and U.S. strategy shifted toward withdrawal. The Tet Offensive became a defining turning point, proving that perception, morale, and narrative could outweigh battlefield outcomes — reshaping how wars are fought and understood in the modern era.
