Explanation:

The ¨hostage situation¨ happened in 1979, at the middle of Carter´s presidency.

Was cataloged as a diplomatic standoff, antagonistically involving the United States and Iran. The conflict was originated when a large group of Muslim students who supported the Iranian Revolution invaded the US embassy located in Iran, posteriorly the group took as hostages US citizens and functionaries.

President Carter´s always had a critic position against this event, referring to it as a ¨blackmail¨ scenario and cataloged the students as ¨sons of anarchy and terrorism¨.
