Israel had better undo the disastrous "disengagement" and retake Gaza ASAP.
First seal the Egyptian border with troops and tanks...same for the Jordanian border.
then move in with infantry and go, literally, door-to-door.
Any home or business which harbos a weapon should be razed. All males associated with that building over the age of 16 should be drug into the street and shot.
No movement into or out of the Gaza should be allowed until the job is done.
Any government in the region who attempts to interfere should meet with the full wrath of the IAF/IDF. No mercy.
