On September 30, 2004, the ISG, under Charles Duelfer, issued a comprehensive report. The report stated that "Iraq's weapons of mass destruction capability … was essentially destroyed in 1991" and that Saddam Hussein subsequently focused on ending the sanctions and "preserving the capability to reconstitute his weapons of mass destruction (WMD) when sanctions were lifted". No evidence was found for continued active production of weapons of mass destruction subsequent to the imposition of sanctions in 1991, though "y 2000–2001, Saddam had managed to mitigate many of the effects of sanctions".
