Advance warning

Now it seems that Tony Blair's government anticipated the quagmire they and we were about to enter into.

Sir David Manning, Mr Blair's foreign policy adviser, returned from talks in Washington in mid-March 2002 warning that Mr Bush "still has to find answers to the big questions", which included "what happens on the morning after?".

In a letter to the Prime Minister marked "Secret - strictly personal", he said: "I think there is a real risk that the administration underestimates the difficulties.

"They may agree that failure isn't an option, but this does not mean they will necessarily avoid it."

The Cabinet Office said that the US believed that the legal basis for war already existed and had lost patience with the policy of containment.

It did not see the war on terrorism as being a major element in American decision-making.

"The swift success of the war in Afghanistan, distrust of UN sanctions and inspections regimes and unfinished business from 1991 are all factors," it added. That view appeared to be shared by Peter Ricketts, the Foreign Office policy director.

There were "real problems" over the alleged threat and what the US was looking to achieve by toppling Saddam, he said. Nothing had changed to make Iraqi WMD more of a threat.

"Even the best survey of Iraq's WMD programmes will not show much advance in recent years. Military operations need clear and compelling military objectives. For Iraq, 'regime change' does not stack up. It sounds like a grudge match between Bush and Saddam."

Tony Blair was the most effective defender of and cheerleader for the war. If this is true, than his credibility, like Powell's, has now been completely trashed.
