The significance of the Korean War to America and the world is outsized compared to its treatment in the standard US History curriculum. The Korean War was the first test of the then new United Nations; without America's participation, the UN might have failed much like its predecessor, the League of Nations. It set the standard for US foreign policy during the Cold War in Asia regarding containment and the Truman Doctrine. Yet, the Korean War gets approximately one paragraph in the textbook and, at best, two powerpoint slides in the classroom. We spend about one day on it. It surely has become the "Forgotten War." Also forgotten, at least in the American historiography of the war, is that the Korean War was truly a civil war between the Korean people. Approximately 4 million Koreans, most of them civilians, died during the war.
