Let's say Stalin decides to create a Soviet Zion in the USSR (Birobidzhan, Crimea, or Kaliningrad) and sends all of Soviet Jewry to this SSR (ASSR?). Eventually, the USSR will collapse and it'll either be an independent polity (if SSR) or autonomous one a la Tatarstan (if ASSR).
What would relations be like between a Soviet Jewish State and Israel?
