Choose one. This is your thread so we need to know what you feel counts as a person being Jewish. I remember reading on here once that someone said Lenin was Jewish because a grandparent or great-grandparent was Jewish, despite him never practicing the religion or taking part in Jewish Russian culture. The Holocaust did so many horrible things. One of the least bad (compared to vivisections, mass murders, etc) was getting it where the Nazi definition of having a single grandparent made a person a Jew, even if they had another religion, culture, etc they thought of themselves as part of. Not saying you are suggesting anything like that, it is just something that came into my head a few days back. Anyways, Lenin is probably out as (if what I once read is correct) Trotsky didn't consider him a jewfish. Apparently Lenin once suggested to Trotsky that he be in charge of a council/soviet, but Trotsky declined, saying that a Russian like Lenin should be in charge, given how many in Europe felt about Jews back then.
I expect that if we go with a secular, partially culturally Jewish leadership that they will- now that I think of it, the Pale (where Jews were supposed to live) would go out of Soviet hands with the Poles and their expansive territories. Which could have been bigger, as the Poles apparently declined the offer of more territory in their peace treaty with the Soviets, as they wanted to keep things man angle Polish and not get too many Belarusians and Ukranians.
Maybe things are less Stalinisn and more multi-party socialism? Lots of autonomous areas, let the peasents and various villages around the union keep autonomy, remove the main landlords, have villages continue to vote locally as they would have on communal matters in the past... Anarchists woudl like that. I mean the original types, not those in movies wanting to destroy all order.
