I agree to an extent. Forcibly breaking up Germany wasn't feasible after either World War
It happened all the same. Even if you disregard East and West Germany, the lands lost elsewhere which weren't previously annexed by the Nazis were quite significant. Some of the areas which were annexed by the Nazis would likely have voted for annexation at the time (Austria), and they were broken off, too.
With both Germany and Russia I am referring to the "core" nation, not peripheral bits.
Yes there was the division of the former from around 1950-90, but that was a product of the Cold War - it was not the original intention of the Allies come the end of WW2.
Depends what you mean by "original". Plenty of plans for dividing Germany were discussed. For a time Churchill wanted to carve out a South German state consisting of Bavaria, BaWü and Austria and unite it with Hungary in a Confederation of the Danube, but the Soviets weren't willing to give up Hungary, and in addition to the three way split in the Morgenthan plan (South, North and an International Zone in the NW) FDR considered both a seven state and five state solution. It also played a part that the British and American zones were swapped so the US got the South in order to be closer to Italy and France, which was originally intended to be the British zone.
