Still I found it rather discussion worthy, Stalin wasn't a big fan of Poland nor was he a fan of the Germans but it seems still plausible especially if Stalin sees the Germans as more useful allies.
So here we have a world where Germany
has more territorial integrity and less expulsions, however not much less.
A DDR which larger is stronger.
Might we see it being more of a threat to Poland in the late 80s provided history has a similar flow.
