He said that he would propose in the meeting let's put all 5+1 demands and those of Iran in a package. Only major demands must be submitted, Mousavian believed, without entering into details, so that both sides would know about the final outcome of the negotiations. 5+1 wants to know that Iran provides utmost clarity. They want to know that Iran won't enrich heavily to develop bombs. Iran for its part wants to know if they adhered their rights would be respected and sanctions would be lifted. When all demands are put into a contractual package then one could talk about implementing them and their priorities be defined. For example, what the West would want more than anything would be the 20 percent enrichment, since it is so important to Israel.
In the first stage they can tell Iran to hold enrichment at the 5 percent level and limit its fuel reserves so in return they would lift sanctions on Central Bank and oil. If Iran is ready to eliminate the West's biggest concern, the West must also do something in return. For example in the case of the sanctions on the Central Bank and oil.
In the same fashion things could be discussed in later meetings. Next time they can tell Iran they want full clarity from Iran and would like the IAEA to visit the army Parchin site. If Iran agrees then they may feel free to say they want to lift the UN Security Council sanctions. To reach agreement such courage from both sides is needed.
Mousavian believed that such agreement is not likely to come by since, first, it is not the US government but the Congress that decides to lift or leave sanctions. So the negotiators would have no authority about that. And second, the EU cannot lift their sanctions when there is still the US sanctions. Because if they do they themselves would be subject to US sanctions. That is why no agreement could be made in 2012 at least.
