We've all read plenty of threads that change around the composition of the Weimar government in the inter-war years in Germany or mix up the Nazi and Communist ranks. To my knowledge, often these threads end with the Weimar government collapsing.
Is it too ASB to imagine the Weimar government actually surviving? I know that it would require some serious PODs, but AFAIK it could be done. What would be needed--no Hitler, no Communists, no Hindenburg?
How would a democratic (at least at first) Germany change the 20th century?
