moved to places with no anti-semitic political forces.
There were no such places, pretty much.
The idea of moving the Jews somewhere where they wouldn't be unwelcome was, in fact, floated - even before WW2. It even got Hitler's personal approval - in 1938, he said that he would let go of any Jews that would want to leave, so long as some other country would accept them. Evian Conference was convened by US for the explicit purpose of determining who that would be. And guess what? None of the states involved, including those that would later become WW2 Allies, agreed to take any additional amount beyond whatever immigration quotas that they had. They were pretty explicit about the reasons, too:
"As we have no real racial problem, we are not desirous of importing one" - Australia
The only country that did accept a significant amount (in proportion to its size and population) was Dominican Republic - ironically, because the dictator in power at the time was a white racist, and considered Jews as white for his purposes (as opposed to black Haitians), and hence wanted an "infusion of white blood" for his nation.
Regarding the whole living memory thing, I think that what matters is how most of the people who are alive today remember it. Basically, if you kick Israelis out and put Palestinians back, how many people would be leaving the homes and the land they were born on and personally grew up on, vs how many would be returning into the homes and land that they were born on. That's what matters because that's the real effect that it would have on people involved, in direct rather some nebulous "historical justice" way. I suspect that such accounting would favor Israelis rather than Palestinians at this point.
