Yes he was. Furthermore, Saddam DID have UN banned weapons and they were being found before and after the start of the war. But he was also right about Saddam's connection to Al Qaeda. THAT TRUMPS ALL. The WH seemed to drop that ball politically and they ran with and went on the defensive about WMD.
My theory:
The White House is playing possum.
Iran sits flanked to the east by Iraq, to the west by Afghanistan.
Coincidence?
If anything, the so-called 'insurgents' have done us a great favor - justifying remaining 'in-country'.
We're still in Iraq and Afghanistan because the War with Iran has just begun.
