Let's assume that the USSR in 1945 only divides the Eastern Prussia between them and Poland, but the other German borders in the East are respected (no Oder-Neisse thing).
Thus, the GDR would also include Silesia and Pomerania (and the Newmark), making it a stronger state thanks to the Silesian resources and bigger population. Which impact would have it in the Commie sphere and the later relations with the FRG and the West? Fall of the Wall would happen the same way?
