your link and comments are about WW II. Versailles was the treaty that ended WW I.
> Germany was in no position to keep fighting.
No one was in 1918 and everyone was exhausted, but "defending the homeland" is a more powerful motivator than anything the Allies had. Germany asked for an Armistice "on the basis of the 14 Points" which did not include occupation.
what lessons? The Allies didn't occupy Germany at all. Germany would have resumed the war if that was what the Versailles conference came up with, and the Allies had no stomach for more war.
