Actually "the WW2" was "revenge for the uprisings" - after the Nazi invasion, large numbers of Polish veterans were rounded up and executed. The actual revenge for WW2 came after the WW2 - in Poland, Soviet Union, Czechoslovakia, Yugoslavia, the former Axis naionals were mostly imprisoned, killed or expelled (including on the newly-aquired territories, like Poland's "Retaken Lands" or Soviet "Kaliningrad" or "Kuryle").
