Why should we expect our Iran sanctions to have impact?

The Oct. 10 editorial on Mitt Romney’s vacuous foreign policy was excellent except for one thoughtless comment. It termed our sanctions against Iran a “historic foreign policy success,” pointing out that “Iran's currency lost 40 percent of its value in two days.” But what have the sanctions achieved? They are impoverishing the Iranian people, true enough. But they haven't reduced Iran’s determination to build a nuclear capability, at least for power generation.

At the same time, we are helping to entrench the Iranian regime by providing it with a scapegoat on which to blame all of its problems.

Half a century of sanctions failed to displace the regime in Cuba. After decades of sanctions against North Korea, the regime is still there, and now has nuclear weaponry. Why should we expect the sanctions against Iran to have any more impact?
