He's wrong. It was a tragic mistake to abandon the south Lebanon buffer zone, and it was shameful to abandon Israel's Christian allies there to their fate. Its a mistake that must be reversed, if for no other purpose than to remind the arabs that attacks cost them land. The land-for-peace one-way-ratchet has to be reversed, and Israel must charge a toll in land for every rocket that crosses the border. The difference is that this time there must be no "occupation", Israel must not return to the business of trying to govern arabs. Instead, a strip of land must be annexed as the penalty, its populace must be compensated and expelled.
The same must happen in the Gaza. A strip of territory must be annexed as the penalty, its arab populace compensated and pushed through to the arab side of the fence. The message must be loud and clear that another annexation will always result every time a rocket, a mortar shell, or a deluded teenager with a dynamite vest manages to cross the fence into Israeli territory.
This is separate from the issue of killing the attackers, which is necessary but ultimately insufficient, since the arabs have an inexhaustible supply of losers ready to blow themselves to bits rather than face life as a muslim, and who can blame them. Their arab brothers won't miss them, the only thing that will register with them is the loss of land, so that has to be the toll. Every time.
Israel's strategy must be working simply because the rabid anti-Israel-Left is demanding that Israel do something else.
Won't happen.
That's the apparent truth that scares the American left -- the Israelis pulled out from Gaza only to get rockets fired at them shortly thereafter. They withdrew from south Lebanon years ago only to see an immediate buildup of mines fronting more rockets. With each passing day we see rockets extending their reach further, into missiles that can reach Tel Aviv. The only solution is to create more of a buffer zone, for the sake of safety. If Israel can effectively do that, the immediate threat of longer missiles is eliminated, and the ability of the US to complete its task in Iraq without being drawn into conflict elsewhere, and Israel to defend itself, both improve.
