I would say we are going through the Kabuki that one would anticipate and it will go one over the next several months which the objective is to get Iran to freeze its nuclear research and any future nuclear enrichment and to find some package of carrots and sticks that will be sufficient to lead them to accept that as the best outcome. I think that is unlikely to succeed but it is the best strategy to be following.
I think the US will have to get the parties together and say ok , here's the deal. Here's the sticks and here are the carrots. Now, we are prepared to do a deal. So far the US hasn't brought forth this carrot that I am sure Iran is very concerned about...namely assurance that we won't attack them to change their regime by force...something that they are very concerned about so I think the pieces are almost in pace but not quite yet.
