So what was President Bush's motive for keeping quiet about this? The material you are citing is all open source so security classification is a moot point.
It’s the stuff that is not being said that’s classified... :-)
The fact that they went over there is merely a bunch of stuff said by others and the U.S. simply ignores it or dismisses them, as either having an agenda of their own, not being reliable or mistaken or any number of reasons. And then the U.S. goes to their “standard line” that “we were mistaken, and there was no WMD there...
Like I said, it works beautifully, as we can well see even here on Free Republic...
