A POD that has been relatively unexplored in my opinion is that of North Korea not invading the South in the summer of 1950 and/or a quick conclusion of the war in Allied victory without the Chinese intervening (which may involve either the Allies voluntarily stopping themselves at the 38th Parallel or possibly the Chinese simply deciding not to get involved even as the Allies push up to the Yalu).
The biggest effect this would have would be on the domestic political scene-without the firing of MacArthur and the stalemate in Korea, President Harry Truman would be in a stronger political position for 1952 allowing him to run for another term in office. The Republican opponent in this case probably wouldn't be Eisenhower as an apolitical general like him wouldn't want to tarnish such an imagine by running against an incumbent President. In that case would Dewey have been nominated yet another time or would Robert Taft have clinched the nomination? Furthermore could Truman have won another term after 20 years of Democratic rule but otherwise in a stable international situation and a good economy? If Truman had won again, would he have been able to push through more legislation such as his national health insurance scheme?
This probably also has some effects on South Korea and Japan although I'm not sure what.
