None were Jews. Many were apostates of Jewish descent. However, by the 1960’s the communist leadership decided to blame Jews for Poland’s problems, while the entire communist world was on an anti-Jewish and anti-Zionist spree following the failure of the USSR’s proxies to destroy Israel in 1967. More than 1/3 of Poland’s remaining Jews were forced to flee from 1968 and the rest were repressed and virtually all Jews were expelled from the communist party in Poland.
To Jews, they remained Jews, because being a Jew is a matter of blood, not of religious beliefs or political views.
Lets blame, no lets bomb the Eastern Europeans, they are responsible for everything..
