Look at South Africa. One state for everyone, equal rights, equal votes. That thought will be so repellent to many that they would rather leave, and good riddance to them.

Not that I as some western internet rando have some unique insight into how things can/should be resolved, just the opposite: some of this is so obvious that even a distant and privileged dummy like me can see it

So again, where do they go?

I don't give a shit tbh. The state of Israel is a rogue state that shouldn't be recognized by anybody and should never have existed. The settlers can either become refugees or rely on the mercy of Palestinians.
