Israel should have pushed all Arabs out of the entirety of historic Palestine after their victory in 1948. Arabs cannot live in peace within Israel anymore than Russians within Ukraine. There is just too much resentment and latent hostility. I would have expelled all the Arabs in Gaza into Egypt and all those in the West Bank into Jordan. Everything orange in the below right image would be an Arab-free zone. Maybe Golan Heights can go to Syria.

Much as if I was Zelenskyy, when this war is over I would march every Russian-supporting separatist to the border and push them into Russia. When the US won the revolutionary war, the Loyalists and British sympathizers were exiled to Canada and elsewhere, you cannot leave the unfinished business of resentful enemies in your midst.
