For quite a while now, policymakers in Washington have worked diligently to try and test a simple hypothesis: that energy sanctions can help derail Iran’s march toward the bomb.
Over the years, this effort has taken the form of a number of legislative initiatives aimed at curtailing Tehran’s energy trade with the world. Of late, however, American pressure has honed in on Iran’s most glaring economic dependency, its deep reliance on foreign refined petroleum. The culmination was the passage by Congress this summer of the Comprehensive Iran Sanctions, Accountability and Divestment Act, a sweeping set of new provisions aimed in large measure at throttling the Iranian regime’s oil sector.
