Assume for a moment that Khalid was the primary or nearly the primary planner, under the leadership of Osama bin Laden, for the many things he cited.
I would emphasize that none of these schemes, the real source of intent to harm the United States that appeared as a nightmare on the morning of September 11, 2001, involved any part of the Baath party or Iraq military or intell forces. This is the difference between a correct target and a wrong target. When you pursue a wrong target you get more complication, less understanding, undesired results and entangling consequences.
I am glad this man was captured, and I hope he has been thoroughly debreifed by people who know how to handle such intell. I know that may sound naive and simplistic. But that's me.
