I suppose the lives of the entire Polish nation are a small price to pay for moral purity?
The Soviets invaded Poland, remember. Maybe you’re blanking out on that one, somehow under the impression that the Soviets “freed” Poland from the Nazis or something.
At that point in the war there were no multiple fronts, there was no lend-lease, there were the Nazis and the Soviets getting away with carving up a sovereign country.
So don’t fucking “Polish lives” me here. If you care about Polish lives you hate both Nazis and Soviets.
