my guess is that both will occur
initially fighting will take place to re-establish pecking order, and while that is going on peace will not achievable. In the end, i would like to think a more reasonable leader will emerge that will step up to the negotiation table. Most of the arab world believes that Arafat screwed over the palestenians during the peace negotions with clinton moderating by not taking that deal. It truly showed arafats true desire -> the end of the israeli state or nothing at all.
