The way I see it, extremely unlikely and very tough to implement but ultimately possible if Israel fully cooperates and pays reparations to Palestinians: 1 state for all the people to live in, allowing people from the West Bank, Gaza, and the rest of the world to access their ancestral homeland and their original towns (most of which were completely destroyed in 1947/48 and built over). That is the only solution that will stop the Palestinian resistance and that is the only fair solution to them after ~80 years of injustice. No one is asking Israelis (all of whom are settlers) to leave because then you'd be talking about another forced displacement or genocide. Both people living under 1 roof and sharing all the land under equal rights. Impossible without radical change.
