Abstract
The 1979 Islamic Revolution in Iran has had an enormous and substantial influence at regional and international levels. This paper studies impact of the Islamic Revolution on the United States of America as a global superpower and the Islamic Republic's main adversary. The research hypothesizes that the revolution has had an increasing bearing on the US politics and government, and that despite limitations and barriers, it has had a supporting effect on Muslims, Shiites and some American intellectuals. Consolidation of Islamic behaviors and sensitivities, growth of tendency to Islam and Shia beliefs, and increase of political demands of Muslims and institutions that are in harmony with the Islamic Revolution are manifestations of such impacts.
