Beware of the crazed ones:
The Iranian President and others believe that if they create chaos and catastrophe, the 12th Imam will return.

In a speech on November 16th, Ahmadinejad spoke of his belief in the return of the Twelfth Imam.
Shiâite ... dominate Iran and form the majority in Iraq, believe that Allah shielded or hid Muhammad al-Mahdi as the Twelfth Imam until the end of time.
Shiâites expect the Twelfth Imam, ... to return to save the world when it had descended into chaos...
in Iran a group called the Hojjatieh believe that humans can stir up chaos to encourage him to return.
In other words, they opposed the notion of an Islamic republic because it would hinder the Twelfth Imamâs return on account of it being too just and peaceful.
Today, in addition to the possibility of Ahmadinejad himself being a member (or a former member), the group has connections to Qom ultraconservative cleric Mesbah Yazdi whom Iranians frequently refer to as the "crazed one" and the "crocodile."
Four of the twenty-one new cabinet ministers are purportedly Hojjatieh members. Some reports state that cabinet ministers must sign a formal pledge of support for the Twelfth Imam.
