Inspectors from the International Atomic Energy Agency (IAEA), the World Atomic Energy Agency, constantly monitor Iran`s declared nuclear facilities and verify that no fissile material is secretly brought to a secret location to make a bomb. U.S. experts estimated at the time that it would take two to three months for Iran to have enough 90% enriched uranium to build a nuclear weapon called an “epidemic period.” By August 15, 2015, Iran will present written answers to questions from the International Atomic Energy Agency (IAEA) about its nuclear program and developments. It also authorized the monitoring of its facilities by IAEA inspectors on 15 October 2015 or before 15 October 2015. UK – Foreign Secretary Philip Hammond said the framework deal with Iran was well beyond what many thought was possible 18 months earlier.  In January 2016, when the IAEA declared that Iran would last until the end of the case, all international sanctions related to Iran`s nuclear program were lifted. Negotiations for a framework agreement on Iran`s nuclear programme took place between the foreign ministers of the countries at a series of meetings held in Lausanne, Switzerland, from 26 March to 2 April 2015. On 2 April, the talks were concluded and Federica Mogherini (High Representative of the Union for Foreign Affairs and Security Policy) and Mohammad Javad Zarif (Iranian Foreign Minister) announced that the eight parties had reached an agreement on a framework agreement. The parties announced: “Today we have reached a decisive milestone: we have found solutions to the main parameters of a common comprehensive action plan,” which they plan to complete by 30 June.     When the framework was announced, Foreign Minister Zarif said: “No agreement has been reached, so we do not have a commitment yet.
No one has any commitments other than those we have already made under the joint action plan we adopted in Geneva in November 2013.  The NPT is a pioneering international treaty aimed at preventing nuclear proliferation and weapons technology, promoting cooperation in the peaceful uses of nuclear energy, and promoting the goal of nuclear disarmament and general and complete disarmament. The treaty is the only binding commitment of a multilateral treaty aimed at the goal of disarmament by nuclear-weapon States. The treaty, which was signed in 1968, came into force in 1970. On May 11, 1995, the contract was renewed indefinitely. A total of 191 states have joined the Treaty, including the five nuclear-weapon States. More countries have ratified the Non-Proliferation Treaty than any other Arms Limitation and Disarmament Treaty, demonstrating the importance of the treaty. This step could be seen as a big step towards a nuclear weapon.
“I know we cannot prevent an Iranian nuclear bomb under the dilapidated and rotten structure of the current agreement,” Trump said in May 2018. If we don`t do something, we`ll know exactly what`s going to happen. In Fordo, no enrichment will be allowed by 2031 and the underground facility will be transformed into a nuclear, physics and technology centre. The site`s 1,044 centrifuges will produce radioisotopes for medical, agricultural, industrial and scientific use. During the June 2012 negotiations in Moscow, the parties did not change their position, but further details of Iran`s proposal were disclosed. The five-point proposal contained recognition of Iran`s right to enrich uranium for peaceful purposes; In exchange for Iran`s cooperation with the IAEA; cooperation in the field of nuclear energy and security; A possible 20% enrichment limit; and several non-nuclear issues.  In the absence of agreement, high-level discussions were suspended. On 3 July 2012, the P5-1 and Iran held a technical meeting in Istanbul between senior officials.
