Ahmadinejad's base - A diagram
* To avoid possible misunderstanding about the implications of this analogy--and to pre-empt unnecessary squawks from the politically correct--it might be worth adding that there is no functional equivalent for the Führer. Yes, there is someone called the Supreme Leader, Ali Khamenei, who is the most powerful single individual in the system. But Khamenei is no Hitler, Stalin, or Saddam Hussein--not even a Mussolini or a Hafez al-Assad. The Iranian regime is a profoundly authoritarian system--with quasi-democratic elements, as we have seen--but not a personal dictatorship.
Here is a beginner's guide to the structure of the Iranian regime's coercive apparatus (from RAND via NIAC via Andrew Sullivan).

Note that, according to the estimates in this chart, the Islamic Revolutionary Guard Corps (IRGC) is about a third as large as the regular armed forces. What the chart leaves out is that the Revolutionary Guard also controls an extensive network of economic enterprises and that a number of (technically retired) Revolutionary Guard officers sit in Parliament. To quote an analysis published in 2007:
Mohsen Sazegara, a founding member of the Revolutionary Guards and [now] U.S.-based Iranian dissident, says though the original charter of the elite force was to create a “people’s army,” years of political and military changes have transformed the unit into a massive money machine. Sazegara says the guards’ business dealings range from construction and manufacturing to illegal importation of alcohol. “I don’t know of any other organization in any country like the Revolutionary Guards,” Sazegara says. “It’s something like the Communist Party, the KGB, a business complex, and the mafia.”(A compact analysis by Sazegara himself is here.) It appears that, over the past decade and a half, the IRGC has increasingly become the backbone of the regime. Supreme Leader Ayatollah Khamenei strongly promoted this process. Does the IRGC continue to function as his instrument, or might he soon find himself in the position of the sorcerer's apprentice? That remains a matter for speculation, but if the June Coup proves to be successful, the outlines of the answer may become more clear over the next few years.
