In April 2015, the P5+1, the 5 permanent members of the UN Security Council plus Germany, negotiated an interim nuclear accord with Iran. Among the key parameters: Iran's enrichment capacity, enrichment levels, and stockpile would be limited; its Fordow site converted into a research center; and the Arak heavy water reactor redesigned. In return, the IAEA would gain greater access for inspections, and U.S. and EU sanctions would be lifted. Many in the U.S. fear that a deal as outlined would not go far enough and, instead of being a benefit, would strengthen Iran's hand in the Middle East. Not to mention the important question of trust. Is this agreement a 'once-in-a-lifetime opportunity' to halt nuclear proliferation, or does President Obama have this wrong?
