West aims to lessen Iran nuclear risk

BRUSSELS/VIENNA - When world powers start talks with Iran next week on a final agreement on their nuclear dispute, the main question for the West will be how to ensure Tehran gives up enough atomic activity to ensure it cannot build a bomb any time soon.

If successful, the negotiations could put to rest a decade of hostility between the West and the Islamic Republic, and head off the danger of a new war in the Middle East.

Ingrained mistrust and a vast gap in expectations between the two sides may still doom the search for a deal: US President Barack Obama has put the chance of success at no more than 50 percent. Some say that is optimistic.

But both sides say the political will is there to reach what would amount to a historic compromise with potentially far-reaching geopolitical and economic consequences.

Iran holds some of the world's largest oil and gas reserves and with nearly 80 million people represents a largely untapped market with vast potential for foreign businesses.

Western governments appear to have given up on the idea, enshrined in a series of United Nations Security Council resolutions since 2006, that Iran should suspend the most controversial aspect of its programme - enrichment of uranium.

Diplomats privately acknowledge that Iran's nuclear work, which Western states fear may be aimed at developing the capability to assemble bombs, is now too far advanced for Tehran to agree to dismantle it completely.

But while Iran may be allowed to keep a limited enrichment capacity, the West will seek guarantees that mean any attempt to build a nuclear bomb would take long enough for it to be detected and stopped, possibly with military action.

Iran says its nuclear programme is entirely peaceful.


"The key question for us is what kind of breakout time we can accept," said a diplomat on one of the six powers' negotiating teams, speaking on condition of anonymity.

Extending that "breakout time", experts and diplomats say, means Iran would have to restrict enriching uranium to a low fissile concentration, stop a large number of its centrifuges now used for such work, limit nuclear research, and submit to highly intrusive monitoring by UN inspectors.

Ahead of the 18 February start of the talks in Vienna, a defiant President Hassan Rouhani pledged that peaceful atomic research would be pursued "forever".

Tehran wants an end to the sanctions that have battered its economy, mainly US and European Union bans on its oil sales. Western states are wary of giving up this leverage too soon.

The talks coordinated by European Union foreign policy chief Catherine Ashton aim to build on a deal last November under which Iran agreed to halt some of its most sensitive work for six months, in return for modest sanctions relief.

That accord made possible with last year's election of Rouhani on a platform to ease Iran's international isolation, was designed to give the sides confidence that a broad agreement is possible.


In the new diplomatic phase, which has to finish in July or the six-month interim accord may have to renegotiated, both sides must satisfy hardliners at home.

In a foretaste of difficulties ahead, Iranian Foreign Minister Mohammad Javad Zarif clashed with US negotiator Wendy Sherman this month over the future of Iran's planned Arak heavy water reactor and the Fordow underground enrichment site.

Israel, which views a nuclear-armed Iran as an existential threat, will push the six negotiating powers - the United States, Russia, China, France, Britain and Germany - to demand that Iran gives up Arak as well as its enrichment plants.

Iran says it is Israel, with its assumed atomic arsenal, that threatens regional peace and security.

Negotiators say one possible way forward on Arak could be to modify it so that it can still produce medical isotopes, Iran's stated goal, without using heavy water which provides a potential route for obtaining weapons-grade plutonium.

Jofi Joseph, former director for non-proliferation on the White House National Security Council staff, said Iran will likely demand it can keep 10,000 machines in operation. It has nearly the same number installed but not running.

But nuclear experts say Iran must sharply reduce its centrifuges in order to extend the time for producing enough weapons-grade fissile material for a bomb. Iran says it only refines uranium for a planned network of nuclear power plants.

The two sides want the final-phase talks to last no more than half a year, and be finished by the time the interim deal expires on 20 July. Many experts believe that is unrealistic.
