1950 – 1953 · North Korea vs South Korea vs China vs UN
UN-led forces and Chinese armies fought to a stalemate in Korea, establishing a divided peninsula that persists today.
After North Korea invaded South Korea on June 25, 1950, the UN Security Council authorized military intervention (Soviet absence allowed the resolution). U.S. General Douglas MacArthur led a counteroffensive, landing at Inchon (September 1950) and pushing north. However, China's massive intervention (October 1950) with 300,000 troops pushed UN forces south. The war became a grinding stalemate; armistice talks began in 1951 but dragged on for years. Major battles included Pork Chop Hill (1952-1953), which changed hands multiple times. The armistice (July 1953) ended major fighting; over 2 million people died (combatants and civilians).
The Korean War demonstrated Cold War conflicts' potential for escalation and the limits of military victory. Korea remained divided, with a hostile DMZ becoming a symbol of Cold War confrontation. The war accelerated U.S. rearmament and NATO expansion. It established the principle of UN-authorized military intervention and demonstrated the viability of communist insurgency against U.S.-backed regimes.
