The WMD (Weapons of Mass Destruction) conjecture refers to the claims made by the U.S. government and its allies that Iraq possessed weapons of mass destruction, which were a primary justification for the 2003 invasion of Iraq. Following the invasion, the absence of any significant stockpiles of WMDs led to a range of interpretations and discussions concerning the intelligence used to justify the war, the motivations behind the invasion, and the political ramifications of the assertions made.
