With any POD after America's entry into WW2 (December 8th 1941), have the WAllies reach Berlin first and subsequently occupy the entirity of Germany's pre-war territory.
What has to happen for this to occur? The Soviets doing even worse on the Eastern Front? The WAllies receiving an extra stroke of luck/genius or two? A Japan-screw in the Pacific? Maybe an earlier completion of the Manhattan Project?
And should the WAllies conquer the entirity of the Reich, what happens to post-war Germany? Unified denazification or permanent/temporary partition? What would a possible WAllied partition of Germany look like? Would Germany lose territory to her neighbours? And what effects would this "Mega-FRG" have in the Cold War?
