Poland's right-wing government just passed a law to jail anyone who says the country helped Nazi Germany carry out the Holocaust. This of course makes me want to see some objective discussion of just that!
There's almost certainly a lot more to be said on Polish resistance to and collaboration with Nazi occupying forces, but this answer by /u/marisacoulter discusses a couple of examples that could get discussion started.
For those who did work with the Nazis, how were they treated after the war?
