If you read the essay you will find out that there is much evidence to suggest that many of the WMD are still in Iraq.
So what? Precious little good that does us now. No WMD were found by GWB, and he had 5 years to do it. So GWB was discredited, as was the GOP that supported him. All of which contributed, IMO, to our losing the Congress in 2006 and the WH in 2008.
Furthermore, you cite "evidence to suggest." Evidence does not suggest; evidence proves. What you have in the essay is speculation.
Post it here and folks will read it.
