9 June 2010: UN Security Council adopts Resolution 1929, which significantly expands sanctions against Iran. In addition to strengthening proliferation-related sanctions and banning Iran from testing nuclear-weapon ballistic missiles, the resolution imposes an arms embargo against the transfer of important weapons systems to Iran. September 8, 2015: Four other senators announce their support for the Iran nuclear deal, for a total of 42. This important step will prevent the Senate from reaching the 60-vote threshold needed to close the debate and pass a resolution of disapproval. On 3 September, Iran`s Supreme Leader Khamenei said the Majlis must make the final decision on the deal.  On the same day, Parliament spokesman Ali Larijani said that he supported the agreement and that „the agreement must be discussed and must be approved by the Iranian Parliament. There will be lively discussions and debates.  November 13, 2017: The IAEA publishes its fourth quarterly report for 2017 on Iran`s implementation of jcPOA. IAEA Director General Yukiya Amano informed the Agency`s Board of Governors that nuclear weapons obligations were being implemented and that IAEA inspectors had access to all the places they needed to travel. Iran has accused the United States of failing to live up to its commitments and Europe has accused itself of American unilateralism. To keep the nuclear deal alive, France, Germany and the United Kingdom have set up an exchange system called INSTEX to facilitate transactions with Iran outside the US banking system, but it is only intended for food and medicine already exempt from US sanctions.
In October 2010, the P5-1 extended a new invitation to Iran to discuss its nuclear program, but did not accept Iran`s request to Turkey or Brazil to participate.  Talks resumed on 6 December 2010 in Geneva, during which the P5-1 sought assurances that Iran`s nuclear programme would remain peaceful and Iran called for the lifting of international sanctions.  At the end of January 2011, diplomats met for the next roundtable in Istanbul, Turkey. The talks failed because Iran insisted that all economic sanctions be lifted as a precondition for substantive talks on its nuclear program.  Immediately after the vote, Mr. Power told the Security Council that the facilitation of sanctions would not begin until Iran met „its commitments“. The government also called on Iran to „immediately release all Americans unjustly imprisoned,“ including Amir Hekmati, Saeed Abedini and Jason Rezaian, imprisoned by Iran and Robert A. Levinson, who disappeared in the country.   Hekmati, Abedini and Rezaian were subsequently released in a prisoner exchange in January 2016, which, according to US Secretary of State Kerry, had been accelerated by the nuclear agreement.  The 2015 nuclear agreement with Iran breaks down and increases the risk not only of a nuclear capability for Iran, but also of a military collision in the Persian Gulf.
