That’s the headline for my latest piece in The National Interest. Opening paras:
On October 1, 1950, the forces of a U.S.-led coalition, acting under the authority of a UN resolution, drove the forces of the Korean People’s Army across the 38th parallel and back into North Korea. It was the culmination of a string of stunning military victories.
From the surprise North Korean invasion in June, U.S.-led forces had taken just four months to mount an amphibious landing at Inchon, break out from defensive lines around Pusan and drive the KPA into headlong retreat.
With the North Korean forces routed, the United States was in a position to dictate the terms of peace. Instead (with Russia absent) the United States secured a UN resolution demanding the reunification of Korea. By October 19, U.S. forces had occupied Pyongyang (the first and almost certainly the only time the United States captured a communist capital). Not satisfied with this, General Douglas Macarthur pushed on rapidly. By the end of October, his forces were close to the Yalu River, marking the border with China.
