Douglas J. Feith, American lawyer and politician, Under Secretary of Defense for Policy
Douglas Jay Feith (born July 16, 1953) served as the under secretary of Defense for Policy for United States president George W. Bush, from July 2001 until August 2005. He is a senior fellow at the Hudson Institute, a conservative think tank.

Feith has been described as an architect of the Iraq War. In the lead up to the war, he played a key role in promoting the claim that the Saddam Hussein regime had an operational relationship with al-Qaeda (even though there was scant credible evidence of such a relationship at the time). A Pentagon Inspector General report found that Feith's office had "developed, produced, and then disseminated alternative intelligence assessments on the Iraq and al Qaida relationship, which included some conclusions that were inconsistent with the consensus of the Intelligence Community, to senior decision-makers."
