Why a Deal with Iran on Nukes Remains Elusive

It was a wild ride last week in Geneva, where the foreign ministers of six world powers assembled with Iranian negotiators for a second round of talks on the Islamic republic’s nuclear program. A deal could come, a deal is likely, a deal is imminent…there is no deal: So ran the reports from the city of diplomacy.

Over the weekend, Secretary of State John Kerry and other U.S. officials professed unqualified optimism. “Diplomacy takes time,” Kerry said after his final session with Mohammed Javad Zarif, Iran’s foreign minister. “All the parties here need time to fully consider the issues.”

Scuttling this historic opportunity to mend relations with Iran could require less time, regrettably, and those eager to keep Iran their favorite pariah state are now fully mobilized. Kerry and his partners in the P5 + 1 group—Britain, France, Germany, Russia, and China—may never get a chance to wield the fancy fountain pens.

​It was French Foreign Minister Laurent Fabius who threw a log in the road in Geneva. With Zarif’s draft agreement on the table Friday, France found it wanting on the question of plutonium production. At that point, a crucial momentum was interrupted.

Iran is now constructing a heavy-water reactor that will be plutonium-capable in the city of Arak, which is 200 miles or so from Tehran. It was not clear exactly what Fabius proposed, but reports suggested he wants construction in Arak, which is due to begin operating next year, to be stopped.

Plutonium is a weapons-grade derivative of uranium. With no exception I can find, news reports fail to note that plutonium—compact, immensely more powerful than uranium—can generate electric power and propel satellite-launching rockets, among its several uses.

Here is the problem: Iran has a right under international law to enrich uranium, and this includes plutonium. The Iranians have been clear on this point all along. No surprises. (Curious note: The U.S. restarted plutonium production last March, after a 25-year hiatus, to fuel its space probes.)

In Tehran on Sunday, Iranian President Hassan Rouhani said not for the first time that the right to enrich is Iran’s red line. “Nuclear rights in the international framework, including uranium enrichment on its soil, are not negotiable,” the reformist leader asserted. “For us red lines are not crossable.”

Note where Rouhani delivered this address. He spoke before the Majlis, Iran’s parliament, which includes some allies and some conservative snipers. Effectively, this was his post-Geneva report. He is operating at his political limit.
