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.
Zionism is just greedy settlerism mixed with that word I forgot which means "conquering back lost land"
It's apparently not enough that Jewish people get land for their own ethnostate (I agree with this for the record), but for some reason it HAS to be explicitly the land in Israel and nowhere else
Even if you accept this premise and view the Arab Muslims as oppressors who shouldn't be there, neither should the Ashkenazi Jews. In fact even the Muslims would be closer to the original inhabitants, with the ladder of priority going something like Mizrahi Jews > Palestinians > Ashkenazi Jews
Revanchism?
Yeah definitely, and honestly I wouldn't even go as far as trying to do an analysis of who "really" should own the land (not that you're trying to do that, I know it's just to make a point). I think as leftists we should really be focused more on who is currently being oppressed rather than trying to figure out who is technically allowed to claim the land.
Like, I don't support land back because native peoples technically own the land via treaties, I support land back because there are currently native peoples who are being oppressed and fighting to have those treaties recognized. Same can be said for Palestine.
