Most of the camps were liberated by the Red Army. I don't see why you feel the need to say "Evil Nazis" unless it is to mock the idea of Nazis being very evil.

The Soviets did actually have a plan to move the Jewish refugees who were refused homes abroad into a designated Autonomous Soviet Socialist Republic, but the plan fell through for reasons that I don't really understand. Maybe just because the land they chose wasn't good or there was just more momentum behind the project to colonize Palestine (which the USSR supported at a critical juncture before going back to opposing for some reason).

In the modern day, I hate the idea of injecting such a reactionary population of millions into a country that has a more lively left than most (though yes, the left has never controlled the Federation and has its own issues besides) when the Israelis could either carve out a part of Germany for themselves or be put in some of the other reactionary shitholes in Europe like England and Italy, where they probably wouldn't make the politics any worse than they already are.
