The United Nations Monitoring, Verification and Inspection Commission (UNMOVIC) and the U.S.-led Iraq Survey Group (ISG) failed to find any of the alleged stockpiles of weapons of mass destruction in Iraq that were used as an impetus for the 2003 invasion.[1] The United States effectively terminated the search effort for unconventional weaponry in 2005, and the Iraq Intelligence Commission concluded that the judgements of the U.S. intelligence community about the continued existence of weapons of mass destruction and an associated military program were wrong. The official findings by the CIA in 2004 were that Iraqi leader Saddam Hussein "did not possess stockpiles of illicit weapons at the time of the U.S. invasion in March 2003 and had not begun any program to produce them."[2]
Immediately following and during these searches, many theories were put forward on how it could be possible for these WMDs to have suddenly disappeared (assuming they were, in fact, there at first). These theories included conspiracy theories, accusations against other governments and claims of successful deception efforts by Saddam Hussein.
After much criticism against the war over the years that followed, every figure that previously supported the claims of WMDs in Iraq, with the exception of U.S. vice president Dick Cheney, acknowledged that they had been wrong.[3] A related debate concerned whether the figures that had built the case for the war had been inadvertently misled by intelligence or that they intentionally deceived the public.[4][5]
