The landslide victory for Eisenhower and the Republican Party in the 1952 Presidential Election showed Democrats that a right of centre, socially conservative America in the grip of an obsessive anti communism would decide their political fate for decades to come. The continuing Korean WarKorean War korean-war The war fought on the Korean peninsula from June 1950 to July 1953 between North Korea (supported by China and the Soviet Union) and South Korea (supported by a US-led UN coalition). It ended in an armistice along roughly the pre-war border, killing approximately three million people and leaving the peninsula divided to this day. North Korea’s invasion of South Korea on 25 June 1950 transformed the Cold War from a European confrontation to a global one. The UN Security Council — able to act only because the Soviet Union was boycotting it over China’s seat — authorised military intervention; the resulting force was 90% American under General Douglas MacArthur. After initial North Korean advances pushed South Korean and American forces to a small perimeter around Pusan, MacArthur’s amphibious landing at Inchon in September 1950 turned the tide dramatically, and UN forces advanced toward the Chinese border. China’s intervention in October 1950 — with approximately 300,000 troops — pushed UN forces back south of Seoul before the front stabilised roughly along the 38th Parallel. MacArthur publicly advocated extending the war to China, was dismissed by Truman, and subsequent negotiations focused on returning to the pre-war border. The armistice of July 1953 created the demilitarised zone along the 38th Parallel that remains one of the most militarised borders in the world. The war killed approximately 36,000 Americans, an estimated 2-3 million Koreans (the proportion of civilians was extraordinarily high), and over 180,000 Chinese soldiers. It left the Korean question unresolved: no peace treaty was ever signed, and the armistice remains technically in force. The Korean War is both a Cold War success story and a demonstration of the Cold War’s human costs. American intervention preserved South Korean sovereignty and the conditions under which South Korea eventually became a democracy and one of the world’s most successful economies. The cost was three years of devastation, a million civilian deaths, and a division that separated families for generations. The war also established the template for subsequent American interventions: a UN mandate providing international legitimacy, American military leadership, allied contributions, and a political objective (containing communist expansion) whose relationship to the military objectives (defeating the North Korean army) was always contested. MacArthur’s dismissal — which established the principle of civilian control over a general publicly challenging the president — is one of the most important constitutional moments in American Cold War history. and the loss of China to communism three years earlier shaped American attitudes to communism and its perceived threat.
