# The United States' Role in the Korean War
The U.S. was the single most important international actor in the war — it was the driving force behind the UN intervention, provided the vast majority of UN forces, and shaped both the conduct and conclusion of the conflict.
## Decision to Intervene (June 1950)
When North Korea invaded on June 25, 1950, the U.S. moved within days to organize a collective response:
- **Truman's decision** was shaped by the logic of containment — the fear, fresh from the Berlin Blockade and the "loss of China," that inaction would embolden Communist expansion everywhere.
- **UN Security Council resolutions**: The USSR was boycotting the Council over China's seat, so it couldn't veto. The U.S. secured resolutions condemning the invasion (Res. 82), authorizing force (Res. 83), and creating a **UN Command under a U.S. commander** (Res. 84). About 90% of UN forces were American.
## Shifting War Aims: Containment vs. Rollback
U.S. policy went through a dramatic evolution:
1. **Defending South Korea** (June–Sept 1950): Defensive perimeter around Pusan.
2. **Roll back the North** (Sept–Oct 1950): After MacArthur's stunning **Inchon landing**, UN forces crossed the 38th parallel to unify Korea. Washington approved this despite warnings.
3. **Back to containment** (Nov 1950 onward): China's massive intervention nearly destroyed UN forces. After a harrowing retreat, the U.S. settled on restoring the status quo ante — roughly the pre-war boundary.
## Command and Civil-Military Conflict
- **Douglas MacArthur** commanded UN forces until Truman **fired him in April 1951** for publicly criticizing the administration and advocating expanding the war into China, possibly with nuclear weapons. This was a landmark assertion of civilian control over the military.
- Successors **Ridgway, Van Fleet, and Taylor** fought the grinding static war of 1951–53.
## Military Contribution
- **Ground forces**: Peaked around 326,000 Americans in Korea; roughly 1.78 million served overall.
- **Air power**: The U.S. achieved total air superiority and waged an enormous strategic bombing campaign that devastated North Korean industry and cities — most North Korea
