I want to continue the previous Versailles threads:
Here are some of my ideas, many would from a position of Britain:
Britain get Heligoland and Borkhum. North German coast to be demilitarized with forts abolished.
Kiel Canal to be abolished to strip away one channel for German naval units. Denmark get Northern Schlewig.
A-H to be balkanized like OTL.
France get A-L and establishes Saarland as a buffer state for 20 years.
Italy get back Fiume and some parts of Dalmatia.
Sponsoring the independent of Bavaria, or even a South German Confederation including Austria, although both were quite unfeasible. If success, we can strip the North, but treat the South well.
Limit on army increase to 200k with medium artillery allowed, other things same as OTL. But no military AND civilian aircraft (OTL German used civil aviation to maintain their skills).
Germany pay reparations, with an amount equal to physical and human damages in Belgium and North France. But the duration would be spread longer. Maybe the absolute amount could be discounted following the acquiring of patents.
After Communism in Germany defeated: Freikorps must be disbanded
Outside the treaty:
Meanwhile, we can spreading propaganda and do other things to exacerbate the remaining differences in ideology and religion in Germany (like separatism in Bavaria and Saxony; or Catholic vs Protestant), if they were small, try to make them as big as possible.
Another option could be press the 100 day offensive to land into Germany, just some westernmost provinces in A-L, Eupen... no need to dig deep. But this would weaken the stab in the back myth.
