In a sign of increased frustration with Iran’s unwillingness to accept America’s “outstretched hand,” the House of Representatives moved yesterday to approve broad sanctions legislation targeting Iran’s petroleum industry. For its part, the Iranian regime remained defiant, pledging continued opposition, even as it struggled to contain the persistent rifts that have emerged in the wake of last summer’s election crisis. Attention now shifts to the Senate and ultimately to the Obama administration, which supports measures aimed at pressuring Iran that receive international backing, a key ingredient for those measures’ success. They are joined in this view by a wide array of national security experts, who in addition to arguing for a multilateral diplomatic approach, have pushed for targeting sanctions on specific key regime figures and entities, as well as fitting any future steps within an overall strategy that continues to keep engagement on the table.
