Well Israel made a huge mistake when they gave in to terrorist demands. This must be a big reason why you should never negotiate with terrorists. Why not just take the southern part of the strip and turn that into a military control zone and blockade from the sea. Everything that enters Gaza should be thoroughly inspected by the IDF long before it reaches "Palestinian" soil to prevent Hamas from smuggling in more weapons. As long as Gaza borders Egypt, the Muslim Brotherhood will continue to supply them. By the looks of it, they don't have enough of a cushion to prevent arms from being smuggled in. Unless of course Israel is allowing it for some odd reason. I'm not privy to that type of information however.
