It is highly unlikely that even the U.S. allies in Europe would join in on further sanctions against Iran in the wake of a nuclear agreement they believe is sensible and positive, India, Japan, South Korea and China—that were pulled into the existing sanctions regime quite unwillingly, they will not willingly sign up for more.
If a deal falls through, the existing multilateral sanctions regime will begin to crumble, countries like India and South Korea, who don’t feel threatened by an Iran nuclear weapon, will be only too happy to find a pretext to break out of the sanctions, in a rush as others do.
Indeed, the proponents of tougher sanctions to get a “better” deal have misunderstood the nature of the Iranian sanctions, the fact is that the United States does not own or control the multilateral sanctions regime, the effectiveness of the sanctions is based on how the international community views the perceived threat and therefore the legitimacy of coercive actions to stop it.
It is illusory to believe that a better deal can be negotiated than the current deal which has been made possible by the combined political will of Washington, Beijing, Moscow, London, Paris and Berlin.
Nor are the five plus one likely to agree to tighten sanctions further just because Israeli Prime Minister Benjamin Netanyahu and the Republicans in the U.S. Congress want them to.
