Iran
After the Supreme Leader, the Constitution defines the President of Iran as the highest state authority. The President is elected by universal suffrage for a term of four years, however, the president is still required to gain the Leader's official approval before being sworn in before the Parliament (Majlis). The Leader also has the power to dismiss the elected president anytime. The President can only be re-elected for one term.
The President is responsible for the implementation of the constitution, and for the exercise of executive powers in implementing the decrees and general policies as outlined by the Supreme Leader, except for matters directly related to the Supreme Leader, who has the final say in all matters. 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 affairs such as signing treaties and other international agreements, and administering national planning, budget, and state employment affairs, all as approved by the Supreme Leader.
History of the Islamic Republic of Iran
Following the 1979 revolution in Iran, the Islamic revolutionary regime of Ayatollah Khomeini dramatically reversed the pro-Western foreign policy of the regime it overthrew. Since then, Iran has oscillated between the two opposing tendencies of revolutionary ardour (promoting the Islamic revolution and struggling against non-Muslim tendencies abroad) and moves towards pragmatism (economic development and normalization of foreign relations). Khomeini's 1989 fatwa calling for the killing of British citizen Salman Rushdie for his allegedly blasphemous book, The Satanic Verses, demonstrated the willingness of the Islamic revolutionaries to sacrifice trade and other ties with western countries to threaten an individual citizen of a foreign country living thousands of miles away. On the other hand, Khomeini's death in 1989 led more pragmatic policies, with Presidents Hashemi Rafsanjani and Mohammad Khatami leading the charge for more stable relations with the west as well as its surrounding, non-Revolutionary-Islamic neighbors—i.e., Saudi Arabia. Following the 2005 election of President Mahmoud Ahmedinejad, Iran has returned to more a more hardline stance, frequently antagonizing the west and its neighbors while battling for control over the region.
