After the 1953 Coup in Iran , the United States and Iran began negotiations on a treaty of amity between them . This treaty was completed in 1955 and signed by Dwight Eisenhower and Hossein Ala . During the Iran hostage crisis following the Iranian Revolution , the United States imposed sanctions on Iran that were in violation of Article 1 of the treaty , but Iran did not invoke the treaty . The United States would eventually invoke the treaty stating that Iran violated Article 2 , Clause 4 of the treaty , which provides for the protection for citizens of either country . The International Court of Justice ( ICJ ) ruled in the favor of the United States . During the aftermath of shooting down of Iran Air Flight 655 Iran sued the United States in the ICJ , with the case being settled out of court . In 1992 , in response to Operation Nimble Archer , Iran would again take the United States to court . In this case the ICJ would rule that while the attacks on Iran were not justified , the United States was not in violation of the treaty
