I am personally very skeptical about that tape. it does not make sense to me that Bin Laden would say such things knowing it would justify everything the U.S is saying to justify the war. For him to come out and say we are partners with Iraq when he knows that could win world unity against Iraq just does not make sense as he is quite an intelligent person (unfortunately in the wrong blind faith religous way) Maybe the tunnels he was in fried his brain.
It seems more probable that the tape is a fake to win world opinion and scare our citizens into giving up all our freedoms and an excuse to attack. I would love to know the truth, but for now I think the clown is dead and someone is making false tapes.
