List of Iranian presidential elections
The President of Iran is the highest official elected by direct, popular vote, although the President carries out the decrees, and answers to the Supreme Leader of Iran, who functions as the country's head of state. Unlike the executive in other countries, the President of Iran does not have full control over anything, as these are ultimately under the control of the Supreme Leader. Chapter IX of the Constitution of the Islamic Republic of Iran sets forth the qualifications for presidential candidates. The procedures for presidential election and all other elections in Iran are outlined by the Supreme Leader. The President functions as the executive of the decrees and wishes of the Supreme Leader. These include signing treaties and other agreements with foreign countries and international organizations, with Supreme Leader's approval; administering national planning, budget, and state employment affairs, as decreed by the Supreme Leader. The President also appoints the ministers, subject to the approval of Parliament, and the Supreme Leader who can dismiss or reinstate any of the ministers at any time, regardless of the president or parliament's decision.

A November 2007 U.S. National Intelligence Estimate assessed that Iran "halted its nuclear weapons program" in 2003; that estimate and subsequent U.S. Intelligence Community statements also assessed that the Iranian government at the time had was "keeping open the 'option' to develop nuclear weapons" in the future. A July 2015 Congressional Research Service report said, "statements from the U.S. intelligence community indicate that Iran has the technological and industrial capacity to produce nuclear weapons at some point, but the U.S. government assesses that Tehran has not mastered all of the necessary technologies for building a nuclear weapon."
In March 2013, the United States began a series of secret bilateral talks with Iranian officials in Oman, led by William Joseph Burns and Jake Sullivan on the American side and Ali Asghar Khaji on the Iranian side. In June 2013, Hassan Rouhani was elected president of Iran. Rouhani has been described as "more moderate, pragmatic and willing to negotiate than Ahmadinejad". However, in a 2006 nuclear negotiation with European powers, Rouhani said that Iran had used the negotiations to dupe the Europeans, saying that during the negotiations, Iran managed to master the conversion of uranium yellowcake at Isfahan. The conversion of yellowcake is an important step in the nuclear fuel process. In August 2013, three days after his inauguration, Rouhani called for a resumption of serious negotiations with the P5+1 on the Iranian nuclear program. In September 2013, Obama and Rouhani had a telephone conversation, the first high-level contact between U.S. and Iranian leaders since 1979, and U.S. Secretary of State John Kerry had a meeting with Iranian foreign minister Mohammad Javad Zarif, signaling that the two countries had an opening to cooperation. Former officials alleged that, in order to advance the deal, the Obama administration shielded Hezbollah from the Drug Enforcement Administration's Project Cassandra investigation regarding drug smuggling and from the Central Intelligence Agency. As a result of the Politico report, Attorney General Jeff Sessions ordered an investigation to determine the veracity of the allegations.
