please tell me what was the alternative to Soviet occupation in Eastern Poland, once Poland rejected a mutual defense agreement against Nazis with the Soviets

There were several alternatives, actually. But most of them would start with Russia not attacking them in the rear after they moved their troops west to fight off the nazis

can you provide a source for that? I know about the Katyn massacre and about other events in which Nazi collaborators/Bourgeois Polish nationalists were killed (as well as some innocent civilians), but AFAIK the numbers don’t go that high

Yeah sure, here’s one that estimates between 250k and 1.5m (but which I believe also includes post-war)

But I presume that if you’re the type that already convinced themselves that all these murdered Poles “must have deserved it” in one way or another, then that number probably couldn’t be high enough anyway

Not to defend the flawed comparison with Trump’s treason, but that’s a very useless take on the M-R pact…

Stalin could have

• not promised the nazis to attack the Poles from the rear
• not attacked the Poles from the rear
• not murdered hundreds of thousands of Poles after high-fiving the nazis after having succesfully attacked the Poles from the rear

I think all of these alternatives would have been more desirable than, well, actively teaming up with the nazis
