We will not go into the details of Pauker's reign. From one side, she helped install Stalinist communism in Romania. From another, she actually tried to combat the growing Soviet influence (obviously, to not much effect). For all the bad and the good Pauker did, one action makes her stand out from contemporaries: after Soviet-Israeli relations soured, Stalin (the one without a skirt) closed off Jewish immigration from the USSR and its satellite states. Pauker didn't follow through, and actually allowed 100,000 Romanian Jews to leave for Israel.
