Seriously though it is a forgone conclusion IMO. Going into Iran that is. All this bullshit about nuclear talks with the EU is just a front. They are trying to negotiate a deal for oil trades. They are obviously at an impasse.
This artlicle clearly lays out the US options:

At any rate, no matter what the British decide, should the Iranian Oil Bourse accelerate, the interests that matter—those of Europeans, Chinese, Japanese, Russians, and Arabs—will eagerly adopt the Euro, thus sealing the fate of the dollar. Americans cannot allow this to happen, and if necessary, will use a vast array of strategies to halt or hobble the operation’s exchange:
· Sabotaging the Exchange—this could be a computer virus, network, communications, or server attack, various server security breaches, or a 9-11-type attack on main and backup facilities.
· Coup d’état—this is by far the best long-term strategy available to the Americans.
· Negotiating Acceptable Terms & Limitations—this is another excellent solution to the Americans. Of course, a government coup is clearly the preferred strategy, for it will ensure that the exchange does not operate at all and does not threaten American interests. However, if an attempted sabotage or coup d’etat fails, then negotiation is clearly the second-best available option.
· Joint U.N. War Resolution—this will be, no doubt, hard to secure given the interests of all other member-states of the Security Council. Feverish rhetoric about Iranians developing nuclear weapons undoubtedly serves to prepare this course of action.
· Unilateral Nuclear Strike—this is a terrible strategic choice for all the reasons associated with the next strategy, the Unilateral Total War. The Americans will likely use Israel to do their dirty nuclear job.
