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.
2009 Iranian presidential election protests
In 2005, Tehran Mayor Mahmoud Ahmadinejad was elected to the presidency, defeating now reformist Ali-Akbar Rafsanjani, placing the conservatives in charge of the government once more. Ahmadinejad would focus his presidency on confronting Israel. His speeches gained international infamy, which usually called for the destruction of Israel and claimed that the Holocaust was fabricated. The funding of anti-Israeli groups went up exponentially, particularly towards Hamas and Hezbollah, which have been labeled as Terrorist groups by the United States. Despite Iran's huge oil and gas reserves, those sectors have been relatively neglected in favor of a nuclear energy program that has cost billions of dollars and has been condemned by Israel and the United States, who claim that the program is a cover up for a much larger nuclear weapons program. As a result, the United Nations has placed sanctions on the Iranian government, which has had a heavy impact on the economy, reducing the value of the rial from a low of 8,000 to the dollar in 2005 to 10,000 to the dollar in 2009.
