I think his real name is Hamid Dawood Muhammad Khalil al-Zawi, from Haditha, and was an officer in the Amn al-'Aameh [General Security Directorate] under Saddam.
Being a Baathist he would have much insight and access to Saddam's entire network and would allow himself to operate in such a shadowy manner.
killed him twice already? In that case kill him again.
That is correct. In fact our military has not given any real importance to this guy as he is just a speech reader for Al Qaeda. The real Al Qaeda leader in Iraq is called "Abou Hamza Al Mouhajer" who give himself the title "the minister of war in the islamic state of Iraq".
The terrorist attacks in Iraq have risen a lot in the last two months and today, as mentioned in this article, there were two big suicide terrorist attacks that killed and injured dozens of people.
The terrorists in Iraq have been greatly emboldened by Obama extreme weakness. We cannot leave Iraq as Obama planned. If we do then Iraq will fall under the terrorist control of Al Qaeda and Iran, shortly afterward the whole Middle East will be under the terrorist control and then we are going to have a catastrophe worse than any nightmare we can ever imagine.
