As I pointed out, the motivation given by al Qaeda for their attacks was NOT what you keep insisting it ought to be. I can think of no reason for them to be coy about their reasons.

I could also point out the al Qaeda activity and attacks in nations that have never deployed any troops anywhere. The African nations mentioned, for example.

The fact that some of the 9/11 terrorists were born in Saudi Arabia is so incredibly irrelevant, I don't know why you seem to be focused on it. Adolph Hitler was born in Austria. Pol Pot was educated in Paris. Karl Marx was born in the German Empire.

As for the rest of your post, you didn't even see the wall you ran yourself into.
