Relations between the United States and Iran have been fraught for decades – at least since the U.S. helped overthrow a democracy-minded prime minister, Mohammed Mossadegh, in August 1953. The U.S. then supported the long, repressive reign of the Shah of Iran, whose security services brutalized Iranian citizens for decades.
The two countries have been particularly hostile to each other since Iranian students took over the U.S. Embassy in Tehran in November 1979, resulting in economic sanctions and the severing of formal diplomatic relations between the nations.
