Israeli Prime Minister Netanyahu may have a very interesting opportunity. I don't know if he realizes it and I doubt he'd be inclined to take it anyway, but I think he has one.
He doesn't want to negotiate with Hamas over the formation of a Palestinian state. At the moment, no one sane would expect him to. The head of the Palestinian authority, Mahmoud Abbas, has no love for Hamas either, but he hasn't been able to afford to do anything without them. However, at this moment, maybe he can.
If I were in Netanyahu's position, here's the offer I'd make:
I'd start with a real offer to the West Bank, as in pulling some settlements and swapping land for the others. I'd give the PA a corner of Jerusalem to put their capital on. I'd also make arrangements to do a better job of sharing water. I'd make an offer to start a Palestinian state with the West Bank alone, but only initially - provisions for Gaza would be in the agreement.
There are two advantages about negotiating over Gaza: There are no Israeli settlements there and its borders are undisputed. That makes things easier.
I'd put Gaza into the equivalent of escrow for the PA. The condition is simple: When the Gazan population votes to recognize Israel, regardless of who their elected leadership is, they can join the Palestinian state already founded on the West Bank immediately.
If and when Gaza joins the Palestinian state, two things happen:
1. Israel helps rebuild housing destroyed in the war, and helps see initially that the civil service is paid.
2. Israel starts construction of a secure rail line between the West Bank and Gaza.
Regarding the rail line: the PA is responsible for policing it. If anyone gets off a train in Israeli territory and hurts anyone or anything inside Israel, the rail line is closed. If any terrorism comes into Israel from the West Bank and the Israelis determine, based on who they know, that the perpetrators are from Gaza, the rail line is closed. If a breach of either happens and the PA informs Israel immediately and cooperates to the fullest extent possible, the rail line does not close.
If there is no military or terrorist action emanating from the new Palestinian state, Israel starts to open borders, resulting in Palestinians able to be employed inside Israel and Israel able to invest easily in Palestine. The probable result of that would soon be the wealthiest Arab country without oil.
From what I know, the majority of the Palestinian population would be fine with this arrangement. There has been a poll taken inside Gaza by a Palestinian pollster early in this war, and results indicated that the majority of the population wanted to stop attempting to destroy Israel and, in fact, many wanted jobs in Israel. http://www.washingtoninstitute.org/policy-analysis/view/gaza-public...
If the majority of the Palestinian population actually is fine with this arrangement and can keep the minority in check, tensions in that area of the Middle East could be mostly defused.
This is one of the only times that Israel might be able to get away without negotiating with Hamas, particularly if they're unsuccessful at defusing them in Gaza during the war.
The problem Abbas would run into is an accusation by Gazans that he sold them out. But he wouldn't have - he'd have gotten them a state. Without recognition of Israel, a Palestinian state can't happen anyway, so he wouldn't have cost them anything they could get otherwise. He could also argue, accurately, that Hamas did not consult Abbas when provoking a war, so why should Abbas be obligated to consult Hamas when forging a peace, particularly a peace with Gazan territorial integrity?
This is extremely unlikely for all sorts of reasons, the first being that I doubt Netanyahu understands that he could create an actual opportunity to negotiate a Palestinian state without Hamas at the table. Still, if it were me, this is the shot I'd take.
