The question of international sanctions on Iran - outside of the UN - is one of cooperation based on mutual interests. The Brits have said they will cooperate. That is, the British Government has said they will cooperate. This is what we're witnessing here. The consequences of not economically destabilizing Iran are obvious. Any bank helping Iran make nukes or support terror will get a slapdown from the appropriate enforcement agency. To your point about Carter – you note it’s a mess. Are you suggesting we lay around in filth, and do nothing? Or are you suggesting sanctions are a limp wrist approach to solving the Iran crisis? The media has gotten bored of it but I can assure you that every day the Iranians are inching closer and closer to an operable nuclear warhead.
Absolutely not! We should use any and all means to insure that Iran comes into compliance. And promote the cohesion of the Anglo-sphere, especially within Iran.

I am suggesting that the time to move forward with harsh sanctions is at hand. The political "damage" has already been pressed on Blair and his party. Congress is not in session. Why wait? Even if Iran rattles sabers and makes life more difficult via their proxies in Lebanon and Iraq. There is not a downside for the US at this juncture.
