Kempe, you forgot to mention that Poland was openly hostile to the Soviet Union. Chauvinist state, they had concentration camp Bereza Kartuzka for jews, ukrainians and belorussians long before the war started. A year before the war, Poland conspired with Hitler and took a piece of Czechoslovakia. And planned to attack the Soviet Union together with Hitler and Japan. And fully supported the “final solution of the Jewish problem”.
You write as if Poland was a peaceful innocent victim of aggression.
