In May 2018, a broad consensus was reached that Iran is complying with the agreement. The agreement, which was reached in Vienna after years of diplomacy and a marathon final round of negotiations of high-ranking diplomats over the past three weeks, is complex and highly technological. Another administration official, who briefed reporters on the story, called the agreement an “eternal obligation to ensure greater transparency.” Which countries negotiated the agreement and what did it get? Although the decision is long awaited and largely telegraphed, it leaves Stagner with the 2015 agreement reached by seven countries after more than two years of gruelling negotiations. The United States will now reinstate the harsh sanctions it imposed on Iran before the agreement and consider new sanctions. Iran has also authorized a rigorous surveillance system allowing international inspectors to access sites suspected of being linked to nuclear weapons. Monitoring and verification. Among the indeterminate provisions, Iran is required to apply and subsequently ratify an “additional protocol” to its safeguards agreement with the IAEA, which gives IAEA inspectors unprecedented access to Iranian nuclear facilities. (As a signatory to the Non-Proliferation Treaty, Iran has pledged never to pursue nuclear weapons, but it has the right to pursue nuclear technology for peaceful purposes.) The Agency publishes quarterly reports to its Board of Governors and the United Nations Security Council on Iran`s implementation of nuclear obligations. The late director general of the agency, Yukiya Amano, called the agreement “the most robust nuclear verification regime in the world.” The reinstatement of sanctions is a violation by the United States of the original agreement, whereas, according to international nuclear inspectors, Iran has been deemed compliant. The agreement allows Iran to do just that at its Natanz plant, but the country would only be allowed to enrich uranium to a maximum of 3.67 percent, which is sufficient for civilian purposes such as power plants, but which is much lower than what is needed for a weapon. According to the New York Times, Iran also said it would continue to cooperate with the International Atomic Energy Agency, the UN`s nuclear surveillance, and that it would return to the nuclear deal if sanctions against the nuclear deal were lifted.
