So what should the United States, Britain, and France have done differently regarding Germany at the End of World War One?
For a better peace post war?
1) More reparations, not less.
2) No restrictions on internal German laws/military, but with reparations demanding payments = too German military budgets until paid off.
3) No territorial losses unless AL going to France, and even then need to have a vote at some point after the war.
4) Occupation of Saarland and Ruhr, while France and other nations war ravaged areas are in recovery/rebuilding.
5) Absolutely enforce a demilitarized zone all along Germany's land borders with France, Belgium, Netherlands, Poland, and Czechoslovakia.
Basically, Germany has to foot to bill for all the damages caused by the war, and they have to pay at least as much on Reparations as they are spending on their Military budgets. While the reparations are still not paid off, occupation of demilitarized zones, without risk of losing these territories are a thing, so faster paid off is faster withdrawal of foreign troops from German soil, and don't piss the Germans off with any of the OTL interference, like restrictions on the German armed forces and such. The cost of the occupation is of course entirely extracted from the German economy, so no nation post war is footing this bill but the Germans themselves.
This doesn't make the Germans want revenge like the OTL TOV does, it doesn't rightfully give the Germans all that much to complain about, and it leaves them their international dignity and they retain their great power status.
I would have some questions now:
If something like this were to have been done, how long would the occupation zones have been in effect? How long until the war ravaged areas of france and other nations could be back up and running? How would the Germans have been included in TTL WNT
