At the time, everyone felt terribly for the Jews, and what the Nazis had done to them, and it kind of made sense to give them somewhere to live. Also, nobody thought much about the Palestinians at the time, and that’s terrible. Finally, no one in the right mind thought all of the Jews who settled in Israel would end up treating others in many ways the Nazis treated them.
Obviously, I’m not saying that Israelis are treating Palestinians the same way the Nazis treated them, but the Jews in Israel have certainly turned from victims into the aggressors in a pretty ironic way that nobody could really foresee. Yes, that arrangement that we have with them should obviously change, and I hope it does soon in order to influence how they treat Palestinians.
But when it comes to Ukraine, rather than refuse to enter a similar agreement, what we should do is learn from what happened with Israel, and try to ensure there are better safeguards from that sort of thing happening in the future. Figuring that out is going to be the tricky part.

Agreed, great take. We can’t fix the mistakes of the past, but we can try to learn from them, which is all anyone can really ask for.
