Read this: The political system of the Islamic Republic is based on the 1979 Constitution, and comprises several intricately connected governing bodies. The Leader of the Revolution ("Supreme Leader") is responsible for delineation and supervision of the general policies of the Islamic Republic of Iran. The Supreme Leader is Commander-in-Chief of the armed forces, controls the military intelligence and security operations, and has sole power to declare war or peace. The heads of the judiciary, state radio and television networks, the commanders of the police and military forces and six of the twelve members of the Guardian Council are appointed by the Supreme Leader. The Assembly of Experts elects and dismisses the Supreme Leader on the basis of qualifications and popular esteem.
