Iraq WMDs: The Intelligence Failure That Launched a War
How false intelligence about weapons of mass destruction was used to justify the 2003 invasion of Iraq
The Case for War
In the months preceding the March 2003 invasion of Iraq, the Bush administration asserted that Iraq possessed weapons of mass destruction and posed an imminent threat to the United States and its allies. On February 5, 2003, Secretary of State Colin Powell delivered a 76-minute presentation to the United Nations Security Council, displaying satellite images, intercepted communications, and diagrams of alleged mobile biological weapons laboratories. Powell stated that Iraq had stockpiled between 100 and 500 tons of chemical weapons agent and was actively pursuing nuclear weapons.
The presentation was built on intelligence that was fundamentally flawed, and in several key areas, known to be unreliable at the time it was presented.
Curveball
The primary source for claims about Iraqi mobile biological weapons laboratories was an Iraqi defector codenamed “Curveball” (Rafid Ahmed Alwan al-Janabi). Curveball had provided his information to German intelligence (BND), which shared it with the CIA. German intelligence officials warned the CIA that Curveball was unreliable — the BND’s own handler described him as “out of control” and possibly mentally unstable. The CIA’s Berlin station chief sent a cable warning that the source had not been verified.
These warnings were ignored or suppressed. In 2011, Curveball publicly admitted to the Guardian that he had fabricated his claims, stating: “I had the chance to fabricate something to topple the regime. I and my sons are proud of that.”
The Niger Uranium Claim
The Bush administration also claimed that Iraq had sought to purchase yellowcake uranium from Niger, citing forged documents. The International Atomic Energy Agency (IAEA) determined the documents were forgeries within hours of receiving them. Former Ambassador Joseph Wilson, who had been sent to Niger by the CIA to investigate the claim in February 2002, publicly disputed the assertion in a July 2003 New York Times op-ed.
In retaliation, senior administration officials leaked the identity of Wilson’s wife, Valerie Plame, as a CIA officer. Vice Presidential Chief of Staff I. Lewis “Scooter” Libby was convicted in 2007 of perjury and obstruction of justice in connection with the leak. President Bush commuted his prison sentence; President Trump pardoned him in 2018.
The Iraq Survey Group
After the invasion, the Iraq Survey Group (ISG), a 1,400-member international team, conducted a comprehensive search for weapons of mass destruction in Iraq. The ISG’s final report, the Duelfer Report (2004), concluded that Iraq had ended its nuclear weapons program in 1991, had destroyed its chemical weapons stockpile in the early 1990s, and had no active biological weapons production at the time of the invasion.
No weapons of mass destruction were found.
Consequences
The Iraq War resulted in the deaths of over 4,400 American service members and an estimated 200,000-300,000 Iraqi civilians. The war’s total cost to the United States exceeded $2 trillion. The Chilcot Inquiry in the United Kingdom concluded in 2016 that the war was based on “flawed intelligence and assessments” that were “not challenged” and should have been.
