Egypt doesnt want an Islamic dictatorship; they don't want another war, which will devastate their economy; they don't want to lose the sinai and its oil + gas reserves They do not need to have the Aswan dam busted. They do not want Iranian infiltrators. Israel is much stronger now than it was in 67 or 73. And if Egypt does not stick with is land-for peace deal, then why should Israel trust that PA/Hamas will?
