WMD conjecture after the 2003 invasion of Iraq
The United Nations Monitoring, Verification and Inspection Commission (UNMOVIC) and the United States-led Iraq Survey Group (ISG) failed to find any of the alleged stockpiles of weapons of mass destruction in Iraq that were used as a rationale for the 2003 U.S.-led invasion. The United States effectively ended the search effort for unconventional weaponry in 2005, and the Iraq Intelligence Commission concluded that the judgements of the U.S. intelligence community regarding the continued existence of weapons of mass destruction and an associated military program were mistaken.
