This looks pretty terrible. Awaiting a formal Iranian response, but there’s no doubt that diplomatic outreach to Iran on the nuclear question suffers tremendously if Iran rejects the Vienna deal. Desired strategies have to bow to emergent realities, in the final analysis, and Iran just doesn’t appear like it will accept an eminently reasonable deal that would buy time for a diplomatic thaw. If this is indeed Iran’s formal response to Vienna, than sanctions look more likely now, and, frankly, appropriate.

Update: via @stevehynd:

But Mrs Clinton, speaking from Pakistan where she is on a whirlwind diplomatic mission to shore-up support for US interests, did not say what conditions would lead Washington to slap fresh sanctions on Iran, and added: ‘We are working to determine exactly what they are willing to do, whether this was an initial response that is an end response or whether it’s the beginning of getting to where we expect them to end up.’
