Israel nor Egypt want anything to do with Gaza. Remember there were settlers who lived there who had their settlements dismantled all in an effort for some sort of peace. The blockade began after the rocket fire.
You fail to see how the rest of the Arab leaders use Israel and Gaza as their own way of keeping their own legitimacy (See Morsi aka Moubarak 2.0). You fail to see how Hamas keeps their legitimacy by touting that they "won" against Israel last week. I'm sure the 100+ people that died would disagree but yet, their legitimacy has increased. I also agree that Abbas has been marginalized by Israel and I don't agree with Bibi's method of dealing with the peace process but as Thomas Friedman once said, we in the west are disillusioned if we believe the same **** that works over here will work over there.
In the middle east, you rule by the sword.
