>>2688959socialist movement in poland specifically never had any nationalist credentials to start with
before war it was a political platform for jewish immigrants from russian empire exclusively, centered around bund
during the war it got thoroughly purged and revitalized with new nkvd approved new blood, mostly jewish immigrants from the soviets
and after thawing supposed nationalist credentials were invalidated by association with soviets via warsaw pact
up to the 60s poles had barely any input into politics in (nominally) their own country
in the 60s gomulka who was a genuine nationalist got outsted for getting too chummy with chinese
in the 70s gierek who tried to create a genuinely polish socialism got outsted for getting too chummy with the free world
in the 80s poland ended up with jaruzel who was no less of an ussr puppet than bierut
and after '89 socialist movement in poland went back to being exclusively a platform for jewish diaspora
