2009 is the thirtieth anniversary of the Iranian Revolution. In 2006 the Bush administration ranked Iran as posing arguably the greatest single threat to America. And throughout 2008 that administration insisted all options were open in dealing with Iran, including preventative strikes. Yet, unlike its decisive intervention to establish Iran as a client state in the 1950s, the US has thus far been unable to force the changes it desires in and from Iran's leadership. This article argues that to help understand this situation it is important to recognize that the Iranian Revolution was and remains nurtured by a contemporaneous “silent revolution” in the international oil industry, even if the Ahmadinejad regime's economic policies especially threaten currently to squander some of the potential afforded by it.
