Anyways, if there's a successful military coup, do you think Germany is going to go to war against Poland (after of course rearming sufficiently to launch such a war) to try to reacquire the pre-WWI German territory?
The priorities would something like that:
1. Build new government in Germany, eliminate political enemies (mostly communist)
2. Restore German territory in 1914 borders (means trouble with Belgium, France, Poland and Sudetenland.)
3. Abolish Treaty of Versailles
4. Revenge on France and England
5. Return of German Colonies in Reich.
You see this perfect recipe for second world war.
But that's depends how the new German Government deal with the situation.
I think they could with Chamberlain find peaceful solution for Sudetenland and other
Belgium is willing to sell Ostkantone to Germany if price is right. (They try it in 1920s, but France intervene)
Poland could give Danzig and Corridor to east Prussia in exchange free access to Baltic Sea and Protection against USSR.
On Colonies, i think that Chamberlain is willing to give Namibia back to Germany as gesture of Peace (between England and Germany)
Left Treaty of Versailles and France
Germany will Abolish Treaty of Versailles stop payment and rearm there Military.
France will intervene, try march into Rheinland and get bloody nose by Germany Army.
now this could could escalate into War between France and Germany (like one of 1870)
Here depends if England under Chamberlain & co remains neutral in this (so long Germany not take detour true Belgium).
