Would Iran deal set new nuclear proliferation standard?

Iranian Foreign Minister Mohammad Javad Zarif and Ali Akbar Salehi, the head of the Atomic Energy Organization of Iran, arrived in Geneva Feb. 21 to hold bilateral meetings with US Secretary of State John Kerry and US Energy Secretary Ernest Moniz. Hossein Fereydoun, President Hassan Rouhani’s senior adviser, is also accompanying the Iranian negotiation team to facilitate consultations and coordination. This is the highest level of talks between Iran and the United States since the 1979 revolution. The nuclear talks between Iran and the world powers are at a most critical moment — and in their final phase — and the chance for a final deal is likely more than 50%.
