Why Israel Needs to Finish the Job Now

There will be endless admonitions to Israel from the Obama administration, the United Nations, and so forth, demanding an early end to the Gaza war now underway. Israel's security needs dictate the opposite: Hamas' capacity to make war must be crippled.

Tel Aviv last week remained one of the safest cities in the world despite the incessant rocket bombardment. In the bomb shelters at the David Intercontinental, we joked about the lack of drinks and canapes at the hotel's hastily improvised guest mixers. The cafe terraces were full every night on Dizengoff Street. But complacency on Israel's part would be misplaced, perhaps even fatal. For the moment Israeli ingenuity has shifted the advantage in rocketry to the defense. That may not be the case for very long. Iron Dome has been extremely effective in containing the damage from a barrage of about 2,000 unguided rockets launched from Gaza. Most of these explode harmlessly in empty areas; the few that fly towards targets of value have been taken down with a 90% successs rate. But the advantage may shift back to the offense some time in the next few years.

Dr. Uzi Rubin, the architect of Israel's missile defense, warned last January that Iran and Syria already have GPS-guided ballistic missiles. The Jerusalem Post reported:

"This is a strategic threat. Even worse news is coming; ballistic missiles are becoming smart,” he said. In the next five to 10 years, Israel’s enemies will inevitably arm themselves with GPS-guided ballistic missiles such as Scuds, [Rubin] said.

“Perhaps Syria already has this capability,” Rubin said. “This can significantly disrupt Israel’s air power. Israel will of course recover. We are talking about escalating a war to quicken it, and end it within three days. They are talking about doing the same. This threat can degrade the IDF’s ground capabilities” via accurate missile strikes on army mobilization and staging grounds, Rubin warned. “It can paralyze Israel’s war economy. And of course, it can inflict massive casualties. I’m not talking about Dresden, but Coventry, perhaps,” he said, referring to cities bombed in World War II.

Iron Dome can defend successfully against a handful of rockets fired simultaneously in the general direction of Israeli cities. At some point Israel's enemies will acquire the capability to fire large salvos of precision-guided weapons at key military or civilian targets and overwhelm the existing defenses. GPS-guided rockets are not that difficult to make. Iron Dome gives Israel a respite, not relief in the long term.
