Whatever Trump proposes will not be an honest attempt at a peaceful, just settlement to the crisis. It will be an attempt by the Trump admin, Israel, and Saudi Arabia to strongarm the Palestinians with the goal of re-orienting Middle East politics away from the Israel/Palestinian conflict and towards one opposing Iran. Applying maximalist pressure to neighboring Arab states to join their regional conflict against Iran has been one of the main focuses of Saudi foreign policy under MBS. So far, it has been a spectacular failure. It will fail in Israel and Palestine just as it has failed in Syria, Lebanon, Qatar, Jordan, and Yemen.
The Arabs in the Levant won't ever agree to it and those who think they will are practicing a foreign policy based on fantasy.
None of this even addresses the issues of a border, occupation, terror, Palestinian state viability, land disputes, water, right of return, Gaza, dozens of other historical and religious sites, settlements, or what to do with the millions of Palestinians living in Lebanon, Syria, Egypt, and Jordan.
The Arabs aren't going to sell all of that away for a bag of silver.
