America can't do a damn thing against us (Persian: آمریکا هیچ غلطی نمی تواند بکند‎‎) is a slogan originally used by the former Supreme Leader of Iran, Ayatollah Ruhollah Khomeini during the Iran hostage crisis, for the first time to assure the Iranians that the United States would not be able to restore the ousted Shah of Iran back to the Persian throne. The statement then became an official slogan for the Iranian Revolution which resulted in the establishment of an "Islamic republic" under Khomeini's rule.
