That very well could be, I do not speak Polish, so I must rely on modern English translations.
I get Polish news from TVN-24 Polish news (English) and historical records.
I know that Poland was divided regarding the European Political Situation leading up to WW II, I believe it was due to WW I and the exit from so much Royal and Aristocratic Rule in Europe.
Before WWII Poland was a rather xenophobic place, where people believed the Jews were drinking baby blood. You don’t see a lot of this in Poland nowadays, in Lvov at least half are still around these lines. And they managed to bring it to Kiev.
