The "right of return" in Israel isn't happening. In fact...I've not heard it come up once in the context of the cease-fire talks with Hamas.

I agree that it's almost certainly not happening. I think a two-state solution also is almost certainly not happening. But Palestinians' desire for a right of return is not at all delusional or irrational, and it remains the overwhelming matter that prevents a deal from being made. That's why Clinton's efforts failed. Not because of Arafat's capabilities, but because the two parties were in fundamental disagreement over a core material issue that no one could resolve to their mutual acceptance.

It hasn't come up in the cease-fire talks because the cease-fire talks were...cease-fire talks. They weren't trying to solve the entire Palestinian-Israeli conflict. Trump decided to vastly expand the scope of the talks to just cut Hamas out of it and bring in regional issues - trying to solve one problem with another - and it worked to get the ceasefire done. But they're not talking about right of return, because no one is bothering to ask whether this deal is one that the Palestinian people want or would accept.
