Ed Morrissey of Captain's Quarters makes his living as manager of a call center. But he also blogs brilliantly and thoroughly. Those who insist that there could never have been a collaboration between the Saddam Hussein regime and al Qaeda on 9/11 need to read Ed's following blog entry, in full. It doesn't prove the case, or claim to, but it makes very interesting reading.
I am always amazed at those who claim, with absolute certitude, that we know that Saddam's regime had nothing to do with 9/11. We don't know that. We don't know either, with any certainty, that Saddam did collaborate on 9/11, but we know that he had motive and opportunity, and we know (read Ed's post) that there is some evidence of collaboration. Not conclusive, but evidence. Read.
Then read this, on how documentary evidence shows that Saddam's regime recruited suicide bombers to work against the United States, before 9/11.
