I don't think I've ever seen this idea mentioned but what if Douglas MacArthur, after the glory he achieved in the Pacific, ran for the presidency and won in 1948 and then appointed a still living George S. Patton as Chairman of the Joint Chiefs? What would the American agenda have been in the Chinese Civil War, the Berlin Airlift, and how would the 1950s have developed, especially the Korean War should the communists still turn out victorious in China?
