from today’s Wall Street Journal:

A tidal wave of Western sanctions might convince the Israelis that the Americans and Europeans are finally serious about countering Tehran. Sanctions against Iran’s importation of gasoline — the country lacks sufficient refining capacity — could shock the regime. The bipartisan Iran Refined Petroleum Sanctions Act, recently introduced in Congress, gives the White House the authority to make foreign companies choose between doing business with the U.S. or exporting gasoline to Iran. A European effort to cripple Iran’s production and transport of liquefied gas — an enormous future financial reservoir for Iran given its reserves — could cause a political earthquake in Tehran. The mullahs just might suspend uranium enrichment.
