Downing Street Memo

The "Downing Street memo" (occasionally DSM, or the "Downing Street Minutes"), sometimes described by critics of the Iraq War as the "smoking gun memo", is the note of a secret 23 July 2002, meeting of senior British Labour government, defence and intelligence figures discussing the build-up to the war, which included direct reference to classified United States policy of the time. The name refers to 10 Downing Street, the residence of the British prime minister.

The memo recorded the head of the Secret Intelligence Service (MI6) as expressing the view following his recent visit to Washington that " Bush wanted to remove Saddam Hussein, through military action, justified by the conjunction of terrorism and WMD. But the intelligence and facts were being fixed around the policy." It also quoted Foreign Secretary Jack Straw as saying that it was clear that Bush had "made up his mind" to take military action but that "the case was thin". Straw simultaneously noted that Iraq retained "WMD capability" and that "Saddam would continue to play hard-ball with the UN.". The military asked "what were the consequences, if Saddam used WMD on day one".

Attorney-General Lord Goldsmith also warned that justifying the invasion on legal grounds would be difficult. However, the meeting took place several months before the adoption of United Nations Security Council Resolution 1441, the resolution eventually used as the legal basis for the invasion of Iraq. UNR687 also provided a pre-existing basis, as it required Iraq to divest itself of "100%" of all WMD capacity, which the Memo agreed it had not.

A copy of the memo was obtained by British journalist Michael Smith and published in the The Sunday Times in May 2005. Though its authenticity has never been seriously challenged, the British and American governments have stated that the contents do not accurately reflect their official policy positions at the time.
