The Iraq Survey Group (ISG) was a fact-finding mission sent by the multinational force in Iraq after the 2003 Invasion of Iraq to find weapons of mass destruction (WMD) programs developed by Iraq under the regime of former Iraqi President Saddam Hussein. Its final report is commonly called the Duelfer Report. It consisted of a 1,400-member international team organized by The Pentagon and CIA to hunt for suspected stockpiles of WMD, including chemical and biological agents, and any supporting research programs and infrastructure that could be used to develop WMD.
