Sure, every decent, right-thinker longs for regime change in Iran. The country’s rulers bludgeon their own people, hurt American interests, lie—and could pose real security threats. But talk of Washington stopping Iran’s nuclear march by overthrowing its regime is more for American than Iranian ears. None of the proposed policies—tougher U.S. rhetoric, more economic sanctions, and/or a military strike—is at all likely to work. Nor do get-tougher proponents credit the fact that most Iranian moderates oppose leaps in American toughness. It usually lands them in jail and unites Iran against America. There is a better U.S. policy—not much better, but better—to strengthen our friends in the Gulf region and try to weaken the Revolutionary Guard regime with quiet and practical persistence.
