re: Ukrainians were actually murderers.

The Ukrainians, especially in the western half of the country, seemed to always to have had a beef with the Poles. They were the biggest collection of and one of the more reliable collaborators that the Germans had in the World War II. Other than the Germans themselves, they may have been one of the biggest participants in the Holocaust. Ukrainian militia forces conducted military operations in cooperation with the German Army in Poland, the Baltic States, and Yugoslavia.

But that was then, and this is now.
