Possibly this article have changed but current Wiki article on Holocaust in Poland looks reasonable (and you can see that many carefully worded phrases probably resulted from long discussions, as Wiki is supposed to work). See below a couple of references to Communist Jews that indeed reflect Stalin’s policy of appointing Jews and other minorities as fronts of his regime exploiting and increasing the tension. We know similar things from our internal strives in 19th century, when Misnagdim and Chasidim in Vilno appealed to new Russian occupiers for support and were ultimately used by Russia to weaken the communities, or even going back to Pompeii invited to solve fighting between brothers. Hopefully, all these fight focus on real criminals – Nazis and Soviets, rather than creating fight between Jews and Poles who were both the victims.
Antisemitism …
Joseph Stalin’s occupation of terror in eastern Poland in 1939 brought what Jan Gross calls “the institutionalization of resentment”,[169] whereby the Soviets used privileges and punishments to accommodate and encourage ethnic and religious differences between Jews and Poles. There was an upsurge in the anti-Semitic stereotype of Jews as Communist traitors; it erupted into mass murder when Nazi Germany invaded Soviet eastern Poland in the summer of 1941
Local people had witnessed the repressions against their own compatriots, and mass deportations to Siberia,[228][229] conducted by the Soviet NKVD, with some local Jews forming militias, taking over key administrative posts,[230] and collaborating with the NKVD. Other locals assumed that, driven by vengeance, Jewish communists had been prominent in betraying the ethnically Polish and other non-Jewish victims.[231]
