If whose plan is followed?
Not my plan- Follow the Mid East - US- and many EU Govts- Iran with Nukes make them think of NK is one example.
That along with other reasons.
Just an article to read thru.
Forget the Handshake - By Yochi Dreazen | Foreign Policy
Stop Enriching Uranium. The most important single ingredient for a nuclear weapon is a large quantity of enriched uranium, and Iran has been steadily amassing more and more of it. The country is estimated to possess 185 kilograms of uranium that has been enriched to a purity level of 20 percent, enough to make about 18.5 kilograms of weapons-grade uranium. If Iran amasses 250 kilograms of the lower-level uranium, that would be a red line for the Israelis, because the amount could be used to produce 25 kilograms of the more potent uranium -- just enough to build a single nuclear weapon.
David Albright of the Institute for Science and International Security, which has closely tracked Iran's nuclear program, says that a deal would almost certainly require Iran to stop enriching uranium up to a purity level of 20 percent and then to either sell some of its current stockpile or put it under international supervision.
Close Down a Nuclear Plant. U.S. officials would also demand that Iran shutter one of its two known enrichment facilities, Natanz and Fordo. Natanz is an older facility that has long been used to produce uranium enriched to low levels of purity. Fordo, a more sophisticated facility, is of enormous concern to American and Israeli policymakers because it's buried deep underground and would be difficult to destroy by air. The German newspaper Der Spiegel has reported that Rouhani is ready to decommission Fordo, a potentially major concession, but the Iranian government has denied any willingness to shutter the facility.
