I mean I think the Iranians are stuck b/w a rock and a hard place here. They've already worked with the US on the first iteration of the Iranian deal, and they gave up all of their enriched uranium -- what they got out of it was sanction relief -- but now they got fucked, cause now they don't have any enriched uranium to use as part of their negotiations with the US to get a better deal, and their economy is under constant pressure from the sanctions.
The only thing they can do to stop this is to renegotiate the Uranium deal with the US, unless they enrich uranium again to the 2011? levels to get a better deal.
Iran probably does not have a path forward, unless they fall to the US or continue to enrich uranium and pray that the US doesn't make their sanctions worse -- as they may lose the public support battle.
