I listened to Glenn Beck today, and it seems his show is the only media outlet extensively covering the Iranian threat. Since it's a talk show, the style is not very fact-checker friendly, but so far, the amazing chain of events that have thus far taken place in Iran and the behavior of their president Adolf Ahmadinejad fits Glenn's assessment.
Glenn pretty much said Iranian President Tom (Ahmadinejad) and his staff are members of the Hojjatieh, and they have usurped the power of the Ayatollah (Supreme Leader, especially in Iran) by claiming that he was appointed by Allah to bring back the 12th Imam, who is viewed as the Shi'ite Messiah to redeem mankind. As you know, war, chaos and Armageddon must happen before the return of the Messiah, and the Iranian President plans to bring just that. Hence the desire to acquire nuclear weapons.
