At the end of the day why are we speculating. Bush stated he was wrong on Saddam and WMD. I thought that would put an end to the speculation myself.
So Clinton had his CIA falsify the reports, Bush was just wrong about the WMDs because he depended on Clinton’s false reports, and Hillary lied because she obviously knew the reports were false.
“why are we speculating”
Because if the rumors were true, that would mean there were literally tons of unaccounted for wmd floating around a lawless civil war zone. That would be bad, and is worth considering as a possibility that we should try to address. And George Bush doesn’t know any more than what intelligence agencies tell him - the same ones that originally told him there were wmd. So his opinion is not a conclusive argument.
I remember before the war, Powell presented a lot of evidence of mobile (and sometimes dual use) facilities in Iraq. These facilities (which were shown in sat photos) have not all been found - so its not unreasonable to believe that they were moved somewhere.
