Iran Nuclear Deal Sealed After Decade-Long Dispute
Iran Nuclear Deal Sealed After Decade-Long Dispute

GENEVA - Iranian and international negotiators have reached agreement on first steps to curtail Iran's nuclear program and ease economic sanctions, after four days of marathon high-level negotiations in Geneva that ended after 2 o'clock Sunday morning.

The foreign ministers of six of the world's most powerful countries stood side-by-side with their Iranian counterpart and the European Union's foreign policy chief to announce the accord, followed by handshakes and hugs all around.

This first-stage agreement, capping decades of dispute over Iran's nuclear program, came at the end of four days of what diplomats called “very tough” negotiations. The foreign ministers of all six nations of the U.N. Security Council's contact group flew in on short notice to seal the deal, from Britain, France, Germany, Russia, China and U.S. Secretary of State John Kerry.

A key dispute that delayed the agreement was over Iran's claim to a right to enrich uranium, which the United States says does not exist for any country.  Secretary Kerry says there is no such right in the agreement.

“This first step does not say that Iran has a right to enrichment," said Kerry. "No matter what interpretive comments are made, it is not in this document.”

At a news conference, Iranian Foreign Minister Mohammad Javad Zarif spoke passionately about the right to enrich. But his phrasing indicated that the agreement recognizes Iran's program, but not any right.

Zarif said, “Many times, at least twice very explicitly this recognition is there that Iran will have an enrichment program. And we believe that to be our right and we are exercising that right and we only require respect for that right.”

According to a U.S. summary of the accord, Iran will have to destroy its entire stockpile of near weapons grade uranium, stop production of even lower enriched uranium, stop construction and installation of centrifuges used to enrich uranium, and freeze construction of a new reactor that could produce plutonium, another nuclear bomb fuel. The summary says Iran also agreed to unprecedented inspections to ensure compliance.

In return, the United States says the international community will not impose any new economic sanctions for the six-month duration of the accord, and will suspend some sanctions on gold and some other precious metals, Iran's auto industry and its petrochemical exports.

The main sanctions, on Iran's oil exports and its financial sector will remain in place.

At London's International Institute for Strategic Studies, Iran watcher and nonproliferation expert Mark Fitzpatrick says what is important now is for the two sides to faithfully implement the preliminary agreement.

“Implementing it will show that they both mean what they say," said Firzpatrick. "It'll be very important that the two sides carry it out so that both sides can show their doubters - and both sides have real skeptics and doubters - that the other side can strike a deal and keep to it.”

But skeptics in Tehran and Washington are only part of the problem. Others, including the Israeli government and Gulf Arab states, say Iran may not accept any further limits on its nuclear program once it has the initial sanctions relief.

U.S. officials say the incentive to work on the next and final agreement will continue because the most damaging sanctions will remain in place. At the International Crisis Group, Iran analyst Ali Vaez agrees.

“Iran will have the motivation to come back and negotiate the comprehensive agreement, which is much more difficult to negotiate and would require much more painful concessions,” said Vaez.

Those concessions, and potentially, an end to all nuclear-related sanctions, are to come in continuing negotiations with a six-month deadline, but as “tough” as diplomats say these talks were, the next round is expected to be even tougher.
