Saddam comes close on many counts, but for a long time he was decidedly not Islamic.
I ought to have specified: his last 15 years or so were decidedly fascistic and had very conscious Islamic overtones. Remember too how Saddam added the Shahadah to the flag of Iraq.
Tehran doesn't tick like that, however much Ahmedinejad would like the role, they're not auditioning for a Führer.
I'm less sure about this than I once was. Khamenei is 73, after all. Not that Ahmadinejad is the boss, but the Pasdaran (which is for all intents and purposes a fascist paramilitary) has increased its power over Iran. The clerics' main counterweight to their power--the Basij--has been absorbed
by the Pasdaran, for example. And we all know what a farce the Iranian elections are.
