Incentives and sanctions will not work, but air strikes could degrade and deter Iran’s bomb program at relatively little cost or risk, and therefore are worth a try. They should be precision attacks, aimed only at nuclear facilities, to remind Iran of the many other valuable sites that could be bombed if it were foolish enough to retaliate.
The final question is, who should launch the air strikes? Israel has shown an eagerness to do so if Iran does not stop enriching uranium, and some hawks in Washington favor letting Israel do the dirty work to avoid fueling anti-Americanism in the Islamic world.
But there are three compelling reasons that the United States itself should carry out the bombings. First, the Pentagon’s weapons are better than Israel’s at destroying buried facilities. Second, unlike Israel’s relatively small air force, the United States military can discourage Iranian retaliation by threatening to expand the bombing campaign. (Yes, Israel could implicitly threaten nuclear counter-retaliation, but Iran might not perceive that as credible.) Finally, because the American military has global reach, air strikes against Iran would be a strong warning to other would-be proliferators.
