What happened
The Vietnam War (1955-1975) began as a civil conflict between communist North Vietnam and American-backed South Vietnam. US military advisors (1955) escalated to massive bombing campaigns (1965-1973) and 500,000+ troops (1968 peak). Tet Offensive (Jan 1968) shocked Americans on home screens, turning public opinion against the war. Despite military successes, US couldn't defeat a determined enemy with popular support and sanctuary in Cambodia and Laos. Massive bombing killed 2+ million civilians; chemical weapons (Agent Orange) poisoned landscapes and people. US withdrew (1973); Saigon fell (1975). Estimates: 1-3 million Vietnamese deaths; 58,000 Americans.
Why it mattered
Vietnam War was the first televised major war and turned American public opinion decisively against military interventionism. The war's failure prompted American strategic rethinking (Kissinger's realpolitik). It delegitimized US moral authority globally and energized anti-war movements. Vietnamese reunification under communism proved that revolutionary movements could defeat Western military power. The war's aftermath—300,000+ boat people refugees, Agent Orange victims, PTSD among veterans—shaped late 20th-century consciousness. Vietnam remains contested terrain: US and Vietnam have since normalized relations (2016); memory of war shapes each nation's identity differently.
