Through Egypt's border with Gaza alot of means of warfare are transfered every day
and only once in a few weeks Egypt's police "discovers" some means of warfare.
Peace with egypt is a cold peace and the situation with syria is much worse, being the supporter of hizballah and best friends with Iran that just today Iran's Foreign Minister said that all muslims in the world must act for the deletion of Israel from the map. A couple of weeks ago after the talks about the Golan Heights began, Syria told Iran they want to tighten their bond with them even more. You can't have peace with a terror supporting country that did nothing to prove their willing for a truthful peace and only talk about getting closer to a country that wants to delete Israel from the map. Israel had already tried it with the Palestinians and that obviously didn't bring peace ("Gaza Pull-Out plan").
