Yes, and everything which happened to the Poles in WW2 is unspeakably saddening and regrettable. Who would not think so, unless he be an animal in human skin?
I just have a last question to you: is the violence meted out to Poles in WW 2 by the Soviets somehow “better” in your eyes? I hope not...
Of course not. But I will point out that the Germans did have specific plans to exterminate the entire Polish race in due course, the Soviets didn't have such plans.
