This 12th Imam will appear on the scene as Islam's "Mahdi" ("savior") (along with Jesus according to them BTW)and bring the world to justice (Islam-style)under Sharia law. (This teaching like so many other Islam teachings are knock-offs of events recorded in the Bible. The Bible has Jesus returning at Armeggedon to defeat all those against Israel and restoring peace on earth while Islam has their Mahdi who they think will do the same.)
Ahmadinejad appears to believe that if he can create such chaos and war, he can hasten the appearing of the Mahdi.
I have read numerous articles where Ahmadinejad comments that he has had meetings with this hidden 12th imam and feels that he is under the power and influence of the 12th imam, and is protected in what he does, by the 12th imam.
According to one article I read, Ahmadinejad sees himself as one of 36 or so "nails" of the coming Mahdi, who has influence to prepare the world for the Mahdi's appearance.

Ok, well that makes more sense than anything I came up with.
I think we need to assume the worse with this guy. He's out to start a war. Therefore...
Time to hit the nail on the head!!!
