I know, however I also heard different opinions.
That phenomenon has been with us since the beginning. Do you remember early on during the war, we'd read all sorts of stories about how WMD had been found, and then each one would eventually be discredited? But people who read a "WMD found" piece of news did not always read the "WMD not actually found" news article (or see it on TV or whatever), so they went around believing WMD had been found. Eventually, we did find a few isolated shells, some warehouses containing pesticides (which are close to nerve gas), and a reference strain of Botulinum bacteria (which was a big deal), and lots of other technical violations of the UN Resolutions, but not much else in the way of WMD.
i think ill agree with centcom.
