Most, no. Not the atheist Jews. During the ethnic oppression and cleansing campaigns in the USSR: the Russians were their primary target throughout the Red Terror and all throughout the 1920s. In the 1930s the Polish, Ukrainians, Finnish and many others, who were slaughtered in proportion to Russians. The Jews as an ethnicity were never included in kill lists.

Yes, during the Great Terror and Red Army Purges a lot of people who called themselves jews were executed as spies, disruprurs, saboteurs but none were taken to Gulag for simply being Jewish.

Stalins mortal enemy was Leon Trotsky who I believe was Jewish. He exiled Trotsky in 1940. He went after Trotsky’s followers, who the majority did happen to be Jewish and many internationalsits.

During the WWII any hint of anti-semitism would not be tolerated by the Red Army. After the war the focus was on ethnic groups that collaborated with the Nazis too much, and nearer to Stalin's death there started processes, which were anti-semitic: the Jewish Anti-Fascist Committee Affair, Cosmopolitans' Case, and the Evil-Doing Doctors Case. These again were processes with a political conspiracy agenda, but a vast majority of victims were Jewish, including people known globally, so the inherent anti-semitic line was easily revealed and created large anti-semitic sentiment, which survived in the society through Khruschev's tenure and was traceable during Brezhnev's. Still, there was no known documented intention neither to expel or exile the Jews to Siberia.

Just as an indication of intentions, if there had been plans to force-expel the Jews to the Far East, why would the Soviets give any autonomy to the exiled nation? I never heard of a Chechen, Krymchak or Volga-German autonomy in Gulag. Neither did I about any autonomy proposed to the Jewish people in the Babylonian Empire.
