Operation Eagle Claw

Operation Eagle Claw, known as Operation Tabas () in Iran, was a United States Armed Forces operation ordered by U.S. President Jimmy Carter to try to end the Iran hostage crisis by rescuing 52 embassy staff held captive at the Embassy of the United States, Tehran on 24 April 1980. 
Its failure damaged U.S. prestige worldwide. Carter himself blamed his loss in the 1980 U.S. presidential election mainly on his failure to win the release of the hostages.
