Let's say in the late 30s, instead of starting a full-scale war, Germany took (militarily) the land it believed was its own, and paid the governments for that land in compensation. So:
Poland was paid for Posen/West Prussia and Teschen Silesia
Lithuania was paid for Memelland
Czechoslovakia was paid for the Sudetenland and Teschen Silesia
Hungary was paid for the little extra parts of Burgenland
Belgium was paid for Eupen-Malmedy
France was paid for Alsace-Lorraine
And some ASB wonked the Führer on the head and negotiated peace with the countries promising no invasions and no aggressive actions in return for accepting the new borders.
Which of those countries would be least likely to accept a few billion Marks in exchange for the new border? What would be the result if all but one or two accepted the new borders and exchange of money?
