Benjamin Netanyahu labels John Kerry's nuclear talks with Iran in Geneva dangerous Israel warns Obama: Benjamin Netanyahu warned John Kerry he was offering Iran the "deal of the century" as the US top diplomat headed to landmark talks in Geneva seeking a nuclear agreement. Benjamin Netanyahu has opened a bitter rift with the US, denouncing a possible interim deal over Iran's nuclear program as "dangerous" and "bad for peace." As US Secretary of State John Kerry and British Foreign Secretary William Hague arrived in Geneva to negotiate with Iran, the Israeli Prime Minister condemned the possible outcome of their diplomacy. The talks stretched into an unscheduled third day on Saturday. Mr Netanyahu wants the US to keep sanctions - and tighten them - unless Iran stops enriching uranium and dismantles the central components of its nuclear program. A "first step" agreement, the subject of the Geneva talks, would result in the US relaxing sanctions in return for Iran reducing, but not halting, enrichment. Mr Netanyahu made clear on Friday he believed such an agreement would be catastrophic. "I urge Secretary Kerry not to rush to sign, to wait, to reconsider, to get a good deal," he said. This is a bad deal, a very, very, bad deal. It's a very dangerous and bad deal for peace. American diplomats say the aim is a "first step" that would freeze Iran's nuclear program for six months to buy time for a comprehensive settlement to be negotiated. US President Barack Obama called Mr Netanyahu on Friday to discuss the talks and "underscored his strong commitment to preventing Iran from obtaining a nuclear weapon." The terms believed to be under consideration would mean Iran stops enriching uranium to 20 per cent purity - close to weapons grade - but continue enriching to the 3.5 per cent level needed for nuclear power stations, albeit on a smaller scale. Mr Netanyahu said this would amount to the "deal of the century" for Iran. "I understand that the Iranians are walking around very satisfied in Geneva, as well they should be, because they got everything," he added. They wanted relief from sanctions after years of a gruelling sanctions regime. They got that. Mr Kerry's decision to abandon a tour of the Middle East and fly to Switzerland suggested an agreement with Iran was imminent. He tried to play down expectations and assuage Israel and hawks in the US Congress who share Mr Netanyahu's worries. "I want to emphasise that there are still some very important issues on the table that are unresolved," he said. Telegraph, London; Bloomberg; AFP
