Iran has also agreed not to participate in activities, including research and development, that could contribute to the development of an atomic bomb. The agreement between the EU and Iran on the Joint Comprehensive Plan of Action (JCPOA) is the culmination of 20 months of “work-intensive” negotiations.   Negotiations have focused on restrictions on Iran`s main nuclear facilities: the heavy water reactor and the production facility of Arak IR-40 (which was under construction but has never been commissioned, as Iran agreed in November 2013 as part of the Joint Action Plan (interim Agreement) not to put the reactor into service or to supply it); Bushehr nuclear power plant; Gachin uranium mine; Fuel Fordow`s enrichment plan; Uranium to Isfahan conversion unit; Natanz uranium enrichment plant; and the Parchin Military Research and Development Complex.  Until September 8, all senators had committed to the agreement, 42 (40 Democrats and two independents) and 58 against (54 Republicans and four Democrats).  Senators were able to support the resolution of disapproval in the Senate by effectively filtering it, rendering it unnecessary for Obama to veto a resolution of disapproval.  But this was only possible if at least 41 voted in favour, and several senators who supported the agreement, including Coons, “suggested that they would prefer a vote on the agreement rather than block it completely.”  The Joint Comprehensive Action Plan (JCPOA); Persian: romantic: barn`meye I`e`me moshtarak (, BARJAM] is an agreement on Iran`s nuclear programme reached on 14 July 2015 in Vienna between Iran and the P5-1 (the five permanent members of the UN Security Council – China, France, Russia, the United Kingdom, the United States – plus Germany) with the European Union. In May 2018, a broad consensus was reached that Iran is complying with the agreement. Omani Foreign Minister Yusuf bin Alawi bin Abdullah welcomed the framework agreement between the 5-1 group and Iran over its nuclear program and called it a “historic agreement.” He called on all parties to reach a final agreement by the June 30 deadline.  After 15 years, many provisions of the JCPOA will end, including most restrictions on Iran`s enrichment program. By this time, by 2030, most of the people who participated in the 1979 revolution will no longer be politically active. Some critics of the treaty believe it is plausible that Iran could then build a nuclear bomb. But Iran should also have ratified the additional protocol and will therefore be subject to enhanced inspection and monitoring by the IAEA.  Several other groups have also conducted campaigns to promote for or against the agreement.
