Condi Rice made an interesting statement several months ago that of course went unnoticed by the press. She was on Hannity's show and was discussing WMD when she said "Of course Saddam's regime had weapons of mass destruction." This happened earlier this year, after the Kaye report had been released. So my feeling is that a few very high level people in the Bush Administration know that Iraq had WMD, probably chemical weapons, and they know what happened to the these weapons. But the proof can't be released to the public because this evidence also is from senstive sources, possibly inside Syria. I am continuously surprised at how the pompous MSM assumes that they have all the intelligence about Iraq and that everything has been made public. Media people act like they know nothing about how the intelligence agencies operate.
Additionally, I suspect much "data" has not been released to the public yet. Saddam has a trial coming up. And, I suspect Iraqi Lawyers are being trained in the ways of law. Syria and Iran sound extremely nervous by the careful way they are currently being "addressed".
