I suspect that with different luck the Nazis 1940 attack could have been defeated. I suspect that in the medium term that would mean Hitler loses.
It could mean that Hitler is killed and the regime overthrown.
The question is do the Western Allies then take steps to force the Soviet Union to leave its part of Poland.
