I read a book about world war two. In the book it talked about a proposal that was considered in 1945 that would've split Germany into "East Germany", under Soviet occupation, and "West Germany" under British and American Occupation. What if this had actually happened? Would East Germany become communist like the rest of Eastern Europe? And what about the West? Would reunification ever be possible, and if so, what would be the cultural and political consequences of a german reunification?
This might see a permanent damage to the German identity, because that means that Hanover and the other northwestern parts of Germany become once more British. Great Britain might keep parts of it. Furthermore, with the eastern parts of Germany (Saxony & Brandenburg) now communist, we might see a distinct Saxon identity rising. Eventually, you get the same result as OTL Japan, with a couple different identities. Three identities, Saxon, Hanoverian (with distinct British influence), and Bavarian, will probably develop, completely reversing the efforts of Otto von Bismarck in the late 1860s.
However, this POD is bordering on ASB, because Stalin wasn't that interested in Central. He was satisfied with his gains in Eastern Europe and the Balkans, and wanted to have more clout in Asia, to prevent the rise of Nationalist China and Unified India as potential rivals to the Soviet Union.
