You'll have to forgive me, Joe. You don't have much of a track record for recommendations. Take this one for instance. You have failed to grasp that we're talking about the whole spectrum of Muslims fighting the US, and not just al-Qaeda. Consequently, you are assuming that the opinions of two people in al-Qaeda fairly represent the opinions of thousands of various fighters. That would be an interesting mistake if only it were an intelligent mistake. Alas! It is not even that.
American military interrogators have said the number one reason the people they interrogate are fighting us is that they are furious with us for killing Muslims. Each time we kill someone, we increase the odds his brother, his cousin, his friend, or perhaps just another member of his religion will take up arms against us -- according to the interrogators. Maybe Usima Bin Ladin and his number two guy hate us for our way of life. But by far, most of the Muslims fighting us are fighting us because we have been killing Muslims.
That's not all that different from the way so many Americans joined the military after seeing the deaths of 9/11. The desire to revenge attacks on your friends, family, nation, or religious group is universal.
Try to understand it, Joe.
