On August 14, 2002, the National Council of Resistance of Iran (NCRI) revealed the existence of undeclared nuclear facilities in Iran, including the Natanz Enrichment Complex, the address of the Kalaye Electric Company, a heavy water production facility under construction in Arak, and the names of various individuals and host companies involved in the nuclear program.  Between September and October 2003, the IAEA conducted a series of plant inspections and met with Iranian officials to determine the history of Iran`s nuclear program. In November, the IAEA Board of Governors adopted a resolution welcoming Iran`s decision to sign the Additional Protocol and suspend enrichment. However, the Committee noted with concern Iran`s previous obfuscation efforts and noted that Iran`s new statements contradicted the Agency`s previous information on its nuclear programme. The Governing Body called on the Director-General to take all necessary steps to confirm Iran`s past and present nuclear activities.  Based on revelations by a group of Iranian exiles in 2002, Iran was suspected of having nuclear facilities. After inspections by the International Atomic Energy Agency (IAEA) and subsequent discoveries, Iran continued its nuclear development despite international resistance. In 2006, the United Nations imposed sanctions on Iran, which were followed by similar actions by the US and the EU. Then bitter confrontations broke out between Iran and the world powers. Trump ran for president and criticized the deal, and the expectation that the U.S. would pull out of it discouraged trade and investment.
