Hitler dies in 1938...how is he remembered/what changes?

[compson III]

World War II was a political and economic necessity for the Nazi Party.  It needed wartime crisis to erase the large economic imbalances within the country.  If the war hadn't happened the debt bubble would have collapsed leading to the disintegration of the Nazi coalition.  I'm not sure if even the war would have been fought substantially different; they would have still been obliged to attack the Soviet Union I think.  Perhaps they could have kept the peace with the U.S. however (i.e. breaking the alliance with the Japanese).

No, mutatis mutandis, personalities are irrelevant.  The Nazis would have had to go to war eventually.

An interesting point though is that if those who had petitioned Hitler to wait a couple years for further economic redevelopment would have prevailed.  Roosevelt might not have gotten reelected in 1940 for example.
