The "one state solution" is the only real way forward but it's not surprising it's not very popular. The Jews would be a minority in this hypothetical country and there are two problems with that:

One, the right wing types types really will only accept a Jewish-dominant theocratic state as an outcome. Everything comes second to that. Even the others feel like they "need" a safe state that's free from generations of oppression against Jews. There are more Palestinians than Jews right now, so giving those Palestinians any kind of political representation is a non starter.

Two, how do you think the Palestinians feel about Jews right now? How do you think they would behave if given political power right now? I'm not saying they'd all turn around and look for equal but opposite revenge but I doubt they're happy about all this. Further, do you think the Israelis are going to want to put themselves in that position?

So because of that. while i think the one state solution is the only realistic non-genocidal way forward i'm not optimistic about it coming to pass.
