After the victory of the Islamic Revolution in Iran, all America's Middle East policies were challenged. After this defeat, America had made all their efforts in the region to regain his lost position. Iranian people, which still had not forgotten the bitter memory of the coup of August 28, revealed His repressed hatred. In an inappropriate and challenging action, America accepted Deposed Shah of Iran by the pretext of treatment. This event led to a revolutionary response to this problem. After this action, in response to American negligence to extradite shah (king), angry group of students, occupied United States Embassy in Tehran and took hostage its staff for 444 days. This event is the beginning of the tensions between Iran and America, which led to the imposition of reprisals. After occupation of embassy by students of Imam Khomeini follower, The United States cut diplomatic ties with Iran and imposing limited sanctions. This was the beginning of the series of sanctions which has continued so far. Initial sanctions were canceled after the Algeria contract. But Iranian movable properties in abroad, on the pretext of compensating the losses of the Islamic Revolution in America continues to be blocked in America. While some of this money was repaid to Iran, but significant amount was never refunded.
