America's sanctions policy is largely consistent and, in a certain sense, admirable. By applying economic restraints, we label the most oppressive and dangerous governments in the world pariahs. We wash our hands of evil, declining to help despots finance their depredations, even at a cost to ourselves of some economic growth.

People who live in hermit states like North Korea, Burma, and Cuba already suffer from global isolation. Fed on a diet of propaganda, they don't know what's happening inside their borders or outside of them. By increasing their seclusion, sanctions make it easier for dictators to blame external enemies for a country's suffering.

Though there are some debatable exceptions, sanctions rarely play a significant role in dislodging or constraining the behavior of despicable regimes.
