In early October, U.S. officials accused Iranian operatives of planning to assassinate Saudi Arabia’s ambassador to the United States on American soil. Iran denied the charges, but the episode has already managed to increase tensions between Washington and Tehran. Although the Obama administration has not publicly threatened to retaliate with military force, the allegations have underscored the real and growing risk that the two sides could go to war sometime soon -- particularly over Iran’s advancing nuclear program.

For several years now, starting long before this episode, American pundits and policymakers have been debating whether the United States should attack Iran and attempt to eliminate its nuclear facilities. Proponents of a strike have argued that the only thing worse than military action against Iran would be an Iran armed with nuclear weapons. Critics, meanwhile, have warned that such a raid would likely fail and, even if it succeeded, would spark a full-fledged war and a global economic crisis. They have urged the United States to rely on nonmilitary options, such as diplomacy, sanctions, and covert operations, to prevent Iran from acquiring a bomb. Fearing the costs of a bombing campaign, most critics maintain that if these other tactics fail to impede Tehran’s progress, the United States should simply learn to live with a nuclear Iran.
