Lessons for Vietnam WarDid United States foreign policy during the Vietnam War reflect lessons gained from the Cold War or the Korean War?
You could certainly argue that the US policy in Vietnam came out of the Korean War. The Korean War would have left US policymakers with the idea that communists were waiting to strike whenever and wherever they could. Policymakers might have thought that North Vietnam would attack South Vietnam if it got a chance, just like North Korea did to South Korea. You could argue that this was the lesson they learned from the Korean War and you could argue that they got involved in supporting South Vietnam right away so as to prevent that from happening in Vietnam.
