Yes idiot. They are. Look up "return of the Mahdi" or "twelfth Imam".
The leadership of Iran is not your ordinary run of the mill Muslim kooks. They are extra improved nutbag wackos with double healpings of super crazy sauce.
They belong to a religious sect that believes it is their religious duty to bring back the Mahdi who is supposed to return for the Muslim version of Armageddon.
How to bring back the Mahdi? Why by causing an Armageddon, of course! What this means in practice is that their religion requires them to start a world wide holocaust so that the Mahdi will return and put everything right in the world which will subsequently be ruled forever by a perfect Islam.
Yes Idiot, there are suicidal Islamic regimes. This one for example.
God! Why do these Ignorant F***ing people open their mouths? I'm pretty sure that Kerry and President idiot also do not understand the nature of the suicidal regime with which they are dealing.
