I agree with Jeff, I love the detail that you bring to the debate. However, and there always is one I still agree with MontyB.
Although there were liberal trends emerging in pre WWI Germany they were not fully nascent, I feel that the despair brought about defeat helped these to emerge, had Germany won, I do not think that the "decadence" of the Weimar would've occurred, in such a compressed time, especially given that a victory would have reinforced the Imperial role, probably keeping the royals firmly in control. Coupled with the fact that Germany would not have had the rampant inflation that followed WWI.
Additionally I'll come back to my original point, Germany innovated out of desparation, had it had the whip hand I do not think that it would've evolved military strategy and tactics to such a degree. I think that we would all be more familiar with the term insurgency before the end of the century had this been the case.
Keep the detail rolling.
