New UN Sanctions against Iran

Last week's UN Security Council vote to sanction Iran for nuclear development was just one vote short of unanimous. But the sanctions themselves were much weaker than the Bush Administration had wanted as proof that Iran is isolated from the international community. Will the sanctions against program help to isolate a major regional power? Is Iran more interested in what's happening next door in Iraq? Are the US and Iran engaged in what amounts to a Cold War in the Middle East?
