||Given Iran's acceptance of the deal and the recojtien of Viena group,as well as IAEA's inaction, if the resolution passes as it stands, wouldn't it be a unique excuse for Iran to withdraw from the NPT? Iran is not gonna get anything more by sticking to the treaty (if it can't get medical isotopes, I can't imagine what-else would be achievable), and may not get a better reason to leave it at some point in future. following the events of the past 8 years, Iran's emphasis on the NPT has so far injected weakness. Iran was probably hoping that while the sanctions track is at play in the UN, she can go further in the nuclear front. the former seems to reach the end point. I am not fully aware of the internal development in Iran at the moment to know whether Iran can resist this last tectonic pressure, but it is unlikely to see a better outcome from the U.S. If Obama has reached the deadlock, there is no reason to hope for a better day on the U.S part.
