@fa6b2777 Great article shedding some light on the very real complexities of the choices people in the nations that were caught between Nazi Germany and the Soviet Union had to face. Shkandrij's book also seems interesting.

Going into a bit more detail about why Polish poliicians might be angry enough to demand deportation could have been a good addition. Ukrainian nationalist movements were responsible for massacres targeting ethnic Poles estimated to have resulted in more than 100,000 dead in Volhynia and Eastern Galicia.

I would also be a little wary of making the conclusion that a good balance was achieved post-war with prosecuting war criminals, many got away with everything they had done because they were so many of them and limited appetite for investigation once the war was over and done with for various reasons. 

 @16555d14 It's a fair point. I certainly yadda yadda yadda'd over much of the Soviet era, because the repression of the USSR basically forbade any proper accountability for the crimes committed in Eastern Europe. All we could really control for was our own immigration policies, the Nuremberg courts, and how we worked with these countries when they became independent. 

But you're right, I could have written a whole other piece on those questions.
