Thoroughly good points, raising the question: in what way could the Allies have dealt with a beaten German Empire so as to avoid the Weimar Republic?Addendum_Forthcoming said:I would argue the war was lost back in the Weimar Republic. The aspirations for creating what would be the Third Reich started then ... and the thing is the Weimar Republic had already prodded and try to cultivate that fascist regime into being back then. They were just hoping that it wouldn't necessarily take the form of what it did. Or more accurate to say, exactly who. Militia training schools and programs as a way of not directly contravening the Treaty of Versailles, etc. I'd argue the Third Reich had the type of political landscape to win. The mindset to win. But economic realities are not trumped by mindset alone. It lost the second it thought that appeasement would last forever.
The Weimar Republic had all the pre-existing designs on Czechoslovakia, etc... There's even some evidence they were already planning the invasion of the Soviet Union years prior the war. Not only that under the guise of perceiving the Western powers as a future threat, Soviet and German relationships were strange to say the least. Various tank development programs and military exercises planned in conjunction with the Soviets on Soviet soil no less. And this relationship went back as far as 1920.
It's the same sort of geostrategic realities that some things are just beyond a nation's grasp. Push your luck, or disastrously allow yourself to believe that diplomacy and mutual necessity aren't weapons on their own, and suddenly you have a string of very pissed off nations that otherwise wouldn't have much to do with eachother on their own arraying against you ... and suddenly you learn quite quickly that the world will align against your interests and you will lose everything.
My initial inclination was to wind that all back even further (Bismarck with his alienation of Wilhelm II from Frederick III and his lack of diplomatic foresight, the ramifications of German nationalism (i.e. 1848), all the way back to Louis XIV!), but that would've been quite a stretch(!)
