That is exactly why I believe the Gaza pullout behind the Israeli Wall makes perfect military sense.
Right now, Israelis in Gaza are playing the role of "human shields" for the Palestinian terrorists as any response to a Palestinian attack must be weighed against the risk of retaliatory attacks against Jewish settlements.
Once Israelis are on one side of the Wall and the Palestinians are on the other side of the Wall, any rocket attack by the Palestinians can be met with massive retaliation by the Israeli Air Force.
Rinse and repeat as often as necessary.
In the end, the Palestinian Authority will have to choose between fighting Hammas or watching 500 pound bombs fall from the sky.
You used up more words to explain what I was getting at---I didn't have that many left. You're exackly right. The Egypts lost their entire airforce for not staying on their side of the canal. The runt king of Jordan ditto his armor for crossing the river. The Syrias lost Golan heights for taking cheap shots and the Lebanons lost nearly their whole town and their tourist bidness for getting stupid. The Gazas that are left will have to swim the canal to get home after the strikes if they take cheap shots over the wall. This is all taking 50 years longer than it should have but it seems to me they are getting one good chance.
