It seems that the blame for the war can be laid firmly at the feet of Tony Blair himself.

WMD intelligence on trial
More evidence of the British weapons of mass deception comes from the trial of US Vice-President Dick Cheney's former chief-of-staff Lewis "Scooter" Libby.<snip>(the article describes Libby's charges then continues thus)...

So far so American, but the Niger uranium claim was central to Blair's WMD spin, and ,ore details of British involvement appeared in the trial. The trial papers include a CIA document called a "Senior Publish When Ready" paper - a phrase used to describe finished intelligence. The document, from June 2003, states:"A centerpiece of the British White Paper last fall was U.K. concern over Iraqi interest in foreign uranium. Given the fragmentary nature of the reporting, CIA had recommended that the UK not use this information in their paper."
So, the CIA had told Blair not to include claims about African uranium in his dossier on Saddam - understandable as the claim was untrue and related to badly forged documents. But somehow, when the Butler committee looked into ]the same Niger uranium claims in 2004, the CIA's warning had been magically transformed. While the Butler Review admitted the CIA had concerns, it said the agency had OK'd Blair's approach:"In preparing the dossier, the UK had consulted the US. The CIA advised caution about any suggestion that Iraq had succeeded in acquiring uranium in Africa, but agreed that there was evidence that it had been sought."
While CIA warnings persuaded some US leaders to drop the phony uranium claim in the run-up to war, the fact that Blair had put the story in the British dossier meant Bush could put the Niger claim in his own high profile 2003 "State of the Union" address, a speech that acted as a rallying cry for war.
Far from being a brake on Bush, Blair effectively helped the President go beyond his own spooks in making false claims about Iraq and WMD.
Either there was collusion between the two in order to bypass normal intelligence channels or Blair is the stupidest lawyer in the world.
I can't believe he had the opportunity to moderate Bush's actions and screwed this up so badly.
