The end of “Israel” will probably go similarly. The people who are fine with living alongside Palestinians as equal citizens will stay, the racial supremacists will leave, at least some war criminals will need to be punished, though it’s basically a society of war criminals from top to bottom, so all of them won’t be feasible. There will be some bloodshed but hopefully not too much.

I’m not deeply familiar with Zimbabwe either, but there wasn’t a white genocide.
