What does one do with a settler population if their mother country won't take them back?

Back when I actually watched breadtube I saw the conversation come up a few time in regards to indigenous landback.

was arguing that pro-landback people were advocating for white genocide while the landback folks were like . In the end the argument I heard in response basically that settlers need to stop worrying about thinking the people they oppressed will be as bad as they know they're being and that generally people would just have to submit to a different government. There were some parts about how it might be necessary to press on Europe to take their settlers back as well, but a lot of this assumes that landback in the Americas is even a plausible reality which with our current reality, is a distant dream, in Palestine who really knows. The stage of settler-colonialism in Palestine is very different than the Americas and like others have said, I'd be willing to believe that those that can't leave but are willing to submit to a new government would be able to stay in some capacity.

I saw a video on Telegram back during the first day of the uprising and some fighters were returning home and dumped a corpse of a soldier onto the ground where a crowd then ran up and started stomping it into the dirt. It's very obvious none of them knew the person, in that moment, the corpse was a symbol of the genocide and oppression of their people, I feel like if the power of the occupiers wanes and they can no longer hold that sort of power that the general animosity might decrease, though it's pretty clear that violence will continue even in more individualist ways for a while should the Palestinians win this fight.
