That's not what was left out of the report was it? Wasn't it that the inspectors had found one and not included it in the report?
A REPORT declassified by the United Nations yesterday contained a hidden bombshell with the revelation that inspectors have recently discovered an undeclared Iraqi drone with a wingspan of 7.45m, suggesting an illegal range that could threaten Iraq’s neighbours with chemical and biological weapons.
Not what we already knew but what Blix and the inspectors just found out but omitted... that's what the report didn't include...
