I'm relieved to hear you're not going to kill him.

Agreed, he can't afford to alienate USA, in the great scheme of things, Gaza is relatively straight forward in terms of a resolution, de militarise, rebuild, interim govt (all hail Tony) for 5 years followed by democratic(ish) elections. With input from other Arab countries.
West Bank will be the sticking point, personally I think there will need to be at least a partial removal of Israeli settlements and land swaps arranged to accommodate the rest. The WB being split into 3 zones with patches here and there plus power sharing is clearly unworkable but that's what was agreed in the Oslo Accords.
Security (for both sides) also has to be a major consideration.
