Make no mistake: U.N. Security Council sanctions and additional U.S. and European pressures are hurting Iran. Tehran is having a harder time importing food and other key goods, its foreign investment is drying up, financial firms and shipping companies are turning down its business, and its central bank is running short of hard currency.

What sanctions are not doing, however, is achieving their goal - to persuade Tehran to abandon its pursuit of nuclear weapons. Not only is Iran making more progress in its nuclear program, it's acting more boldly in its region, threatening U.S. interests while distributing weapons that are killing U.S. troops. Because neither current nor additional sanctions alone will deter Tehran, and because a nuclear Iran would be a disaster for the United States and the world, Washington must seriously consider a military option.

Are sanctions capable of derailing Tehran's nuclear drive? Some skeptics reject such measures altogether, preferring to deal with Tehran by either accommodation or containment. Others point to the spotty historical record of sanctions in altering state behavior in arguing that they will similarly fall short of forcing the ayatollahs to rethink their long-standing nuclear ambitions. For example, sanctions were found to be successful in only a third of the 105 instances in which they were applied between World War I and the end of the Cold War.

As the past year has shown, however, Tehran may well turn out to be the exception to the rule—but only if the Obama administration (and Western governments more generally) make swift and skillful use of the economic and strategic means at their disposal.
