When Qaddafi fell, his vast cache of advanced weapons was looted. A bunch of surface-to-air missiles ended up in the restive Sinai. Apparently, some may have even ended up in Gaza as well and Israeli commercial airliners are taking off and landing, assuming that they are in the crosshairs of these SAMs. The recent bombings in Cairo, and this downed helicopter, raise the question of whether Egypt might descend into Syria-level chaos. It's still unlikely, but it's more of a probability now than ever before.
