Gordon Brown has claimed the UK was "misled" over the Iraq war because the US defence department failed to pass on information casting doubt on Saddam Hussein's destructive capability. The former prime minister, who was chancellor when the decision to go to war in 2003 was made, said it was "astonishing" that top-secret US intelligence was not shared with Britain. He claimed that only after leaving office did he become aware of "crucial" papers held by the US Department of Defense and believes the course of history could have been different had the information been shared.
In his memoir My Life, Our Times, Brown said: "When I consider the rush to war in March 2003 – especially in light of what we now know about the absence of weapons of mass destruction – I ask myself over and over whether I could have made more of a difference before that fateful decision was taken. "We now know from classified American documents that in the first days of September 2002 a report prepared by the US joint chiefs of staff's director for intelligence landed on the desk of the US defence secretary, Donald Rumsfeld. "Commissioned by Rumsfeld to identify gaps in the US intelligence picture, it is now clear how forcibly this report challenged the official view.
"If I am right that somewhere within the American system the truth about Iraq's lack of weapons was known, then we were not just misinformed but misled on the critical issue of WMDs. "Given that Iraq had no usable chemical, biological or nuclear weapons that it could deploy and was not about to attack the coalition, then two tests of a just war were not met: war could not be justified as a last resort and invasion cannot now be seen as a proportionate response." He added that some form of international action was appropriate due to Saddam's continued failure to comply with UN resolutions.
The UK was part of the coalition led by the US which invaded Iraq after American president George W Bush and Tony Blair accused the dictator of possessing weapons of mass destruction and having links to terrorists. As chancellor, Brown said his only official role was to find funds for the war. After an inquiry lasting seven years, the Chilcot Report found the former Iraqi dictator posed "no imminent threat'' at the time of the invasion of his country in 2003, and the war was unleashed on the basis of "flawed'' intelligence.
Brown said that British intelligence which he and Blair saw in 2002 suggested a capability, if not a production programme, for weapons of mass destruction. However, the top-secret US report is said to have conceded that knowledge of the Iraqi nuclear programme was based largely – perhaps 90 per cent – on analysis of imprecise intelligence. Brown claimed the paper suggested that previous assessments relied "heavily on analytic assumptions" rather than hard evidence.
