I'm curious why on Monday Iranian President Mahmoud Ahmadinejad began his speech at Columbia University....rather than end with a prayer that Allah would hasten the coming of the Islamic Messiah known as the "Mahdi" or the "Twelfth Imam" or the "just and promised One" as he did in 2005 and 2006 in his speeches at the U.N., the Iranian leader actually began the speech this way.... "Oh, God, hasten the arrival of Imam al-Mahdi and grant him good health and victory and make us his followers and those to attest to his rightfulness"....why has he moved the prayer to the front of his remarks?....it's not yet clear, but it's important to note that in 2005, Ahmadinejad was telling colleagues that the end of the world was just two or three years away, and that the way to hasten the coming of the Mahdi was to annihilate Israel and the U.S....that was two years ago....now, he's no longer burying the lead....yet much of the American media is....they don't seem to realize how central Ahmadinejad's Shiite Islamic eschatology (end times theology) is to Iran's current foreign policy....and that's why they are missing how dangerous this regime really is....when the Mahdi arrives on earth, Shiite scholars say he will appear in Mecca and Medina, but where does he go then?.....not to Iran....not to Jerusalem....not to Europe or Russia....he supposedly heads for Iraq -- Kufa, to be specific....that's what Shiite leaders have taught for centuries....and this helps explain why Iran is sending insurgents, weapons and money into Iraq, to create the conditions of chaos and carnage into which the Mahdi can arrive, finish off the U.S. and Israel, and set up a global Islamic caliphate headquartered in Iraq....who's the leading Shiite insurgent in Iraq?....Muqtada al-Sadr....what's the name of his militia?.....the Mahdi Army. Why is the American left completely blind to the existential threat posed by radical Islamic leaders such as Iranian President Mahmoud Ahmadinejad?
