Danielle Pletka, head of the American Enterprise Institute's (AEI) foreign policy shop. "The biggest problem for the United States is not Iran getting a nuclear weapon and testing it, it's Iran getting a nuclear weapon and not using it. Because the second that they have one and they don't do anything bad, all of the naysayers are going to come back and say, "See, we told you Iran is a responsible power. We told you Iran wasn't getting nuclear weapons in order to use them immediately." ... And they will eventually define Iran with nuclear weapons as not a problem."

The loudest, most influential organisations pushing for sanctions against Iran have an open pro-Israel agenda, regardless of their positioning on the political spectrum. The best resourced of all is the American Israel Public Affairs Committee (AIPAC), self-described as "the most influential foreign policy lobbying organisation on Capitol Hill". AIPAC lobbied aggressively for the recent bellicose bill proposals, featuring them and its lead sponsors on the front page of its website. Sanctions are "having an impact" and "more are needed", the accompanying captions read. AIPAC is also a key backer of the push to sanction Iran's central bank, a move that some Iranian officials consider an act of war.
