The highly racial framing you are using is one that even Hamas rejects. Palestine is an Arab country in the sense that it's mostly Arab, it is not Arab in the sense of being an ethnostate like Israel. Likewise, the point of conflict here is not that the Israelis are Jews, but that they are former colonizers, aside from the second-class citizen Arab (etc.) Israelis. Jews do alright in Palestine right now.

Even if it just stopped there, the fact that there would be some hate crimes as blowback from the genocide committed by Israel is a much smaller and more manageable problem than having a rogue state launching hellfire missiles indiscriminately at cities.

But I think there are other factors to consider, first among them being that people of Palestine have the much more important jobs of a) reconstruction and b) the extensive trials that will be required, along with their associated fact-finding missions. There's a lot of shit to do and most of it is for the direct benefit of Palestinians, plus any spite they have can be satisfied by the just convictions of countless Israeli criminals. It's not like they are some racist savages who won't be satisfied until the last Jew has been bled dry, contrary to their hasbara depiction. Overwhelmingly, what they want is to live in peace, because so many of them have spent their whole lives living under violence.

So nothing about this seems like it would be an equivalent problem to leveling one of the most densely populated cities in the world, plus all the other shit that is going on. It is, in function, just a refusal to allow any blowback Israelis caused to actually hit them, no matter how many Arabs get slaughtered in the meantime.

I do agree with the other commenter that it would be good for some NATO-sphere country or countries to set aside land and migrate out those non-criminal Israelis who want to leave, but that's almost certainly not ever going to happen. I acknowledge that it's possible, but the use of Israelis to these states is as a ranks of a militarist state terrorizing its neighbors. What use would Israelis be to the imperial project in Alberta, Canada?
