It is really too bad that the "other side" so often blindly follows self appointed "leaders" for causes that may be anything but just.
Just from my point of view. Saddam had WMD's. Documented, as he had used them against Iran and even his own people. He managed the inspection program in a furtive way to further the indication he had something hidden. Intelligence from many different countries were convinced he had them. Post war intelligence indicated even "he" thought they were to be implemented in the upcoming battle at the time. The fact that they were not found does not automatically indicate he did not have them. We haven't found Jimmy Hoffa or Osama yet, but there is no question they exist somewhere, in some form.
