General consideration needed when you think about Iran = Hojatieh!
"Hojatieh" headed by looney Ayatollah Mesbah Yazdi, wants the quick return of the 12th Imam, a boy who disappeared down a well in the 1300s and is a direct descendant of the Prophet Mohammad.
Ahamdi-Nejad is a desciple of Mesbah Yazdi and a true believer of the Hojatieh.
The Hojatieh creed, which was too crazy even for Khomeini, who created the Islamic regime in Iran, says the 12th Imam will return to bring salvation to mankind (similar to the second coming of Christ concept) BUT ....
In order for him to return for this purpose there has to be sufficient death, misery, oppression, pain and suffering in the world to make it worth his while (so to speak).
THUS.... to encourage a speedy return of the 12th Imam, the Hojatieh (presently the dominant Islamic creed in Iran with Mesbah Yazdi the power behind the throne and likely to become the Supreme Ruler in the very near future) insists that their duty is to create enough death, misery, oppression, pain and suffering to entice the 12th Imam to return.
AND.... Anyone who acts to prevent all this suffering etc., is against Islam (as per Hojatieh) and as an apostate should be killed.
SO.... fear of mutual self-destruction - as was the case with the Soviets and to some extent with the Chinese - is exactly the opposite of what the Hojatieh want, fear or believe. They would love mutual self-destruction to occur so that they create enough reason for their 12th Imam to return to the world and bring Islamic salvation.
Whenever you thin of Iran think of this and understand that anything and everything you have held dear and reasonable about them NO LONGER HOLDS TRUE.
Pol Pot of Cambodia, who murdered millions of his own countrymen, some for simply having weak eyesight and wearing glasses (inference of being educated) was a Boy Scout and really sane conmpared to what we have at the helm in Iran.
And we quibble whether we should perhaps not bomb Iran and allow this bunch of lunatics to have nuclear weapons to implement their Hojatieh philosophies on the rest of the world.
The only real question is which "innocents" to save. The Iranian population of some 70 million (though only a few hundred thousand would actually perish) or HUNDREDS of millions around the globe when Iran unleashes nuclear weaponry AND THEIR OIL WEAPON - in the near future and triggers something even Hitler could not dream or even wish to achieve.
