Not accurate.
At worst, you could claim that Bush's administration did not know for certain what it took Duelfer and the rest of the ISG a year and a half of unrestricted access to Iraq and Saddam's secret files to find out.
Hindsight is always 20/20, and Saddam had a proven history of concealing active weapons programs from inspectors.
The actual report is worth looking at. It also sheds a lot of light on the machinations between Saddam and parts of the international community.
