And is it just coincidence that reversal of US fortunes in war fighting coincides with our involvement in the UN?
After the catastrophic retreat, MacArthur lost much support and was replaced. We were forced to completely withdraw from North Korea, which again was a military error because we had a secure defensive base of operations within the Wonsan Perimeter, dominated from the air and by naval support.
We caused the Chinese well over a million casualties before the armistice, but Korea can hardly be called a victory.
