So here's the premise, can you think of any way that Douglas MacArthur is made the supreme Allied Commander, instead of Eisenhower? There is no question that MacArthur had the credentials, after all he was the youngest division commander in WWI, and the youngest Chief of Staff. Basically, the reason he was sent to the Phillipines was because Roosevelt couldn't stand him.
However, as I ask again, what if MacArthur was sent to command the Allied Forces in Europe rather than be sent to the Pacific theatre? If so, what strategies would he pursue? Would Nazi Germany be defeated sooner or later?
