Suppose that Germany is incapable of pursuing it's irredentist goals, this wouldn't require just the nazis coming to power but Germany being to weak to pursue those goals under any government, in order to have this you need some catastrophic event like a civil war.
So my idea for a 1930's German civil war is this the Nazis are more radical and are against aristocrats and industrialists as much as against communists., thus they are more leftist in their economics and tahe over the the support of the working class from the communists and the social-democrats.
Also some leader(Who?) creats an other german fascist movement this one is more religious and agrarian it get's large support amongst peasants,they are also against aristocrats and industrialists.
The two fascist movements are not having friendly relations however in late 1931 this leader dies and is replaced by somebody who is for a united front with the Nazis.
In the elections of July 1932 this united front wins a majority in the reichstag but they are denied their victory by a military coup(by Whom?) forcing them out of parliment, the united front reacts by revolting , as they have major support amongst both peasants and city-inhabitants they rapidly form militias this is strenghten by the fact that several german army units defect to the front. Thus in August 1932 Germany is wrecked by civil war between the united front and the military plus other anti-fascist groups.
The war rages on for 4 years(How?) during this time Poland and Lithuania divide East Prussia between them(nobody recognizes it though) and the French establish an independent Rheinland Republic. The military is victorious, and after it's over the German economy is wrecked beyond measure, millions of refugees have fled Germany, and Germany lost important portions of it's territory.
It won't be capable of pursuing any kind of military action for a large number of years.
In this scenario many would say that the Soviets would invade Europe(Red Alert 1 scenario), but let's say that Stalin is more cautious.
What conflicts would arise in this Europe.?
There are many posibilities:
1. Hungary vs. Little Entente not likely even with Italian support.
2. Bulgaria vs. Balkan Entente likewise
3. Hungary,Bulgaria and Italy vs. Little Entente/Balkan Entente don't know
4. Poland vs. Lithuania don't know
5. Italy vs. Albania very likely
6. USSR vs. Baltic nations or Finland or Poland or Romania possible but may lead to Anglo-French attack on USSR
7. Fascist Greece vs. Turkey don't know however Italy might help Greece
What others?
