Nope, 90% of the whole institution was always over 90% ethnic Poles.
Bullshit. Jews made up the majority of UB/SB. The leaders' names read like the invitation to a Bar Mitzvah
Jakub Berman - JEW, Solomon Morel - JEW who ran away to Israel to escape prosecution in Poland, Anatol Fejgin - JEW, Roman Romkowski - CRYPTO JEW (real name Natan Grunspan - changed name to appear more Polish like many other crypto jews), Jozef Rozanski - ANOTHER CRYPTO JEW real name Jozef Goldberg, Jozef Swiatlo - more CRYPTO JEW - real name Izak Fleischfarb, Julia Brystiger- JEWESS, Roman Zambrowski - MORE CRYPTO JEW real name Rubin Nassbaum, Stefan Staszewsk - CRYPTO JEW real name Gustaw Szusterman, ... the list goes on and on....
Don't see too many Kowalskis, Jastzebskis, etc. unless they're CRYPTO JEWS who changed their names to sound more Polish like countless have. Many of these people are still alive and surprise surprise support the leftists. They went from Marxist to neo-Marxist. Now they're pushing lgbt, multikulti, etc. to destroy Polish society and identity since they can't quite repress, torture and kill like in the past.
Proof is right here from a dissertation from Duke University - says that JEWS held half of the managerial positions in MBP.
Paczkowski (2008) referred to a report of October 20, 1945 by Nikolay Selivanovsky, the chief Soviet adviser at the Ministry of Public Security. According to this report, Jews made up 18.7% of the ministry's workforce, and held half of the managerial positions.
No matter how you slice it, the fact remains that there was a disproportionate amount of Jews in the post WW2 PRL government, the security services, etc. especially in the top positions. The Jews brought about Communism while the Poles opposed it. And just like today they're trying to force LGBT, multikulti and all this other BS on Poland once again.
