Germany – German Chancellor Angela Merkel has stressed that the agreement is good for the negotiating partners.  This is due to the fact that the Iran agreement contains sunset clauses or parts of the agreement that eventually expire. Under the agreement, restrictions on Iranian centrifuges disappear after 10 years (2025) and restrictions on uranium enrichment disappear five years later (2030). As a result, there are concerns that Iran will rapidly develop a nuclear weapon when these restrictions expire. Restrictions on Iran`s nuclear program under the deal could survive. In this context, there is a massive distrust of Iran in the United States (and vice versa), and Washington has long feared what might happen if the Iranian regime developed a nuclear weapon. Iran made great strides in this regard in the 2010s, hence the Obama administration`s efforts to orchestrate the nuclear deal. When the pact was finally concluded in 2015, it was widely hailed as a great diplomatic achievement. 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.  «The Islamic Republic of Iran will end its final restrictions in the nuclear agreement, which means limiting the number of centrifuges,» the Iranian government said in a statement in the Times. «As a result, Iran`s nuclear program will have no production restrictions, including enrichment capacity, percentage and number of enriched uranium, and research and expansion.» In other words, Tehran has accepted restrictions that would allow it to have enough enriched uranium to maintain the country`s energy needs without the ability to make an atomic bomb. Total enrichment should only take place at the Natanz plant and Iran`s stockpile of 12 tonnes of low-enriched uranium – sufficient for several nuclear weapons if it continues to be enriched – should be reduced to 300 kg for 15 years. At the time of the agreement, the administration of then-US President Barack Obama expressed confidence that the JCPOA would prevent Iran from building a secret nuclear program.
Iran is committed to «exceptional and robust surveillance, verification and inspection.» In January 2016, when the IAEA declared that Iran would respect the end of the case, all international sanctions related to Iran`s nuclear program were lifted. The agency`s director general, Yukiya Amano, said the report concluded that until 2003, Iran had made «coordinated efforts» for «a series of activities» relevant to the development of a nuclear explosive device. Iran continued some activities until 2009, but there was «no credible evidence» of weapons development, he added.
