The western bank has reached a point where they no longer have a continuous enough mass of land under their control to have a semblance of independence from Israel without expelling all the Jewish settlements in their vicinity. As a third party observer, one of the reasons the settlements take such a center stage is because they put everything under Israeli control, in much the same way the Israelis originally gained de facto ownership of land under British rule. It really is quite brilliant.
I also deeply suspect that it is left unspoken but understood geopolitically that as soon as the US withdraws their guarantee of Israel, Israel attempts to take as much land around them as they can maintain control of due to their concerns about a lack of "Strategic Depth" , Israel can't effectively respond to invasion due to being a postage stamp of a country, which would be a less than ideal outcome for any president no matter how much political capital they get from anti-israel movements.
So long as the status quo is maintained, something that isn't going to be easy to do, I predict that the israeli-palestine conflict resolves itself within the next two generations at most. Gaza probably having many people forcibly relocated and the rest absorbed into Egypt.
