Like carve out a place between Russia, Belarus and Ukraine in the former Pale of Settlement. Establish a bunch of Yiddish language schools there. Have it become a center of Jewish culture. Sure, there are already Ukrainians, Russians and Belorussians there but there were already people in the far east too.
Very biased given its the Stalin Society, and it mostly exists to talk about Khrushchev selectively talking about the crimes of resettlement yet funnily forgetting to mention the ones he was involved in
