...For us and in the meantime, I mean. For the Egyptian people, it will be quite a different story. They have voted, and they are going to get what they deserve. The country is fast running out of financial reserves, and a crunch on vital food imports is only a couple of months away. Egypt will become a huge version of Somalia, and will be increasingly dependant on the Oil Arabs' aid to feed its immense population, thus possibly preventing it from getting too close to the Iranian mullahcracy. Securing Israel's southern border against terrorist incursions from lawless Sinai will become increasingly costly, and the defense budget will slowly ramp up to close of what it was in the bad old Seventies, and that means that life is going to get a lot tougher for ordinary Israelis. Nobody here sees Egypt going to war anytime soon. They know they will lose if they do, but the Camp David agreement is dead and buried. It was never much of a peace mind you, and bilateral trade never really picked up. For Israel, it was good while it lasted, since the reduction in military expenditures allowed for real development and economic expansion. OTOH, the ordinary Egyptian citizen never saw any upside to it, since all Egypt got for it was US military aid, and you can't eat Abrams tanks. There is also a (slim) possibility that since Hama"ss is a Moslem Brotherhood offshoot, and the Gaza population is culturally indistinguishable from the Nile Delta Egyptians, Egypt will gradually assume sovereignty over the Strip, thereby voiding the "Palestinian" narrative and enticing Jordan to do the same with the West Bank Arabs. This would be an outcome that does not entail peace of any kind, but at least it would have the merits of clarity. The Islamic winter that has just descended on the Arab world will clear eventually, and Israel needs to make sure it does not figure among its casualties. As I said before, this will be very costly, but the blood cost can be minimized.  

Funny you're jumping to the H5N1 bird flu topic without warning, but I can guess your associative pathway included the fact that the largest number of human fatalities (about a dozen AFAIK) caused by this virus have been in Egypt. Influenza, as well as all other sheathed viruses, would make piss-poor bioweapons as they are too fragile to be weaponized. They can be used, but an infected human vector would be necessary. A suicide bomber equipped with conventional explosives would be far deadlier, and quicker. Viral epidemics can be stopped as soon as the key surface antigen of a causative agent has been identified. The Israeli Prime Minister Office lavishly funds the Biological Institute in Ness-Ziona, which job it is precisely to do that, while conducting research on which biological and chemical agents are most likely to be selected by a genocidal foe. By the way, the Israeli MoH has apparently broken this year's flu epidemic, by handing out European-made vaccine shots FOC and without too much bureaucracy. I just walked into the clinic a fortnight ago and came out vaccinated after five minutes. The nurse was unusually charming, a far cry from the customary KGB medical corps veterans who populate our HMO facilities...
