When Gen. Douglas MacArthur Put the Hurt on North Korea

Based on the merits of this article, with MacArthur in charge, the Allies were winning. When Truman relieved him of command, the war bogged down to a stalemate, the repercussions of which we see to this day.

The North Koreans were too busy trying to reduce the Pusan Perimeter to worry about their rear. Their failure to garrison Seoul-Inchon was a master stroke but US troops crossing the 38th was something the Chinese had warned us about. That was our disaster.

MacArthur was a disaster during the Japanese attack. His troops were starving before the Japanese came to Bataan. The Navy didn't want him in the Theater at all. They felt that all they needed was a few island bases and a lot of bombers.
Inchon was a master stroke that captured the North Korean Army. The Chinese warned us that if US troops crossed the 38th Parallel they would intervene. Boy did they, The entire 8th Army was surrounded. If not for the threat of nuclear attack it would have been the largest defeat in American Military ever had. Eisenhower was a pacifist who never actually engaged in combat but he was an organizational genius. I don't see either as "great" warriors
