Jews always supported Polish during Napoleonic times…(early 1800s). A lot of good it did when the Poles collaborated with the Nazis.
My of my ancestral lines was from Suwalki. B”H they got out in the 1870s.
I have been to Poland a number of the times in the 1980s on business. I could not wait to leave. I felt as if I had a target on my back. I did not get that feeling in other Eastern Bloc countries or in Germany.
As to your supposition that Solidarity led to 1+ million Soviet Jews being freed, I think that is quite a stretch. There were many reasons why the Soviet Union and later Russia were glad to be rid of 1+ million Jews.
