So, using HANS BLIX'S UN REPORT, we see he was finding, and destroying, WMDs in Iraq shortly before the invasion.
Negative. All WMD's actually destroyed (a few shells, item 119 of the report) were known to have existed prior to the Inspectors leaving in 1997. Because they were known to exist, slated for disposal under UN supervision, the Iraqis kept them for disposal at a future date, like when the inspectors returned. The rest of the stuff listed in Blix' report, which you linked, were not WMD's, nor did Blix claim they were at any time. Shells filled with water & HE are not WMD's, nor are minor misc components listed in his report. He found no WMD's not already declared by the Iraqis, no matter how desperately you want to say that he did. Follow up by US forces after the invasion confirmed his findings.
