Sir John Chilcot has some bad news for the many Britons pining for the day Tony Blair will be tried for war crimes. The former Prime Minister did not lie to get the UK into the Iraq war.

This is the clear conclusion of a sweeping inquiry into the war released on Wednesday by Chilcot’s committee, a report that took longer to produce than the British military involvement in Iraq.

The closest Chilcot comes to criticising Blair’s use of the intelligence produced by his government is that he at times did not express the full nuance and uncertainty contained in those reports.

But Blair’s statements about Iraq’s chemical, biological and nuclear weapons programs were consistent with what the professional analysts, spies and military officers were telling him.

“It is now clear that policy on Iraq was made on the basis of flawed intelligence and assessments,” Chilcot said in a statement. “They were not challenged and they should have been.”

In this one sentence, Chilcot has obliterated a genre of Iraq war literature.

Remember that for the “Bush Lied, People Died” crowd, Blair and United States president George W. Bush pressured analysts and manipulated intelligence to get the war they wanted. Instead, Chilcot said that Blair should have been more sceptical of intelligence on Iraq’s weapons programmes.

And yet you still see this kind of thing all the time.

On the US side, the notion of cynical Bush Administration information manipulation should have been put to rest years ago. As two reports from the Senate Select Committee on Intelligence made clear, the US intelligence community — with a few dissenting agencies — agreed that Saddam Hussein was hiding chemical, biological and even nuclear weapons programmes.

Chilcot’s report, though, includes so much detail on the British side, it is worth recapping some of his findings.

Let’s start with a February 27, 2002, assessment from the Joint Intelligence Committee, the panel that oversees intelligence products for the British Government. It says: “Iraq also continues with its chemical and biological warfare (CBW) programmes and, if it has not already done so, could produce significant quantities of BW agent within days and CW agents within weeks of a decision to do so.”

On nuclear, that assessment said Iraq continued a programme to develop a weapon, although it was at best five years away from producing a warhead.

These judgments, it should be said, were in keeping with British and US intelligence assessments for years.

Chilcot’s report concludes: “The ingrained belief that Saddam Hussein’s regime retained chemical and biological warfare capabilities, was determined to preserve and if possible enhance its capabilities, including at some point in the future a nuclear capability, and was pursuing an active policy of deception and concealment, had underpinned UK policy towards Iraq since the Gulf conflict ended in 1991.”

Chilcot does not let Blair off the hook. He says Blair was warned that an invasion of Iraq could strengthen al-Qaeda. He concludes that Britain did woefully little preparation for the day after the defeat of Saddam’s forces. And he uncovers a note from Blair to Bush promising his support for the Iraq war, whatever happens.

But on the issue of prewar intelligence, Chilcot’s criticism is so mild, it barely registers. It revolves around a September 2002 British Government dossier on Iraq’s weapons of mass destruction. Chilcot says this dossier was more nuanced than a foreword to that document written by Blair.

For example, Blair said the assessment had concluded “beyond doubt” that Iraq “continued to produce chemical and biological weapons, that [Saddam] continues in his efforts to develop nuclear weapons, and that he had been able to extend the range of his ballistic missile programme”.

The actual dossier was not quite this definitive. “The assessed intelligence had not established beyond doubt that Saddam Hussein had continued to produce chemical and biological weapons,” Chilcot’s report says.

Instead, the dossier said that Iraq “had continued to produce chemical and biological agents”.

On nuclear weapons, the reed is even thinner. The British dossier didn’t say Iraq had continued a nuclear weapons programme, as Blair said. Instead, it said Iraq had made covert attempts to “acquire technology and materials which could be used in the production of nuclear weapons”; “sought significant quantities of uranium from Africa, despite having no active nuclear programme that would require it”; and “recalled specialists to work on its nuclear programme”.

You have to squint pretty hard to conclude that Blair was lying here. A more reasonable explanation is that politicians use language differently from intelligence analysts. Blair was making the case for a policy that he believed. That policy was based on the view of the US and British intelligence community — and, for that matter, plenty of other national intelligence services — that Saddam was concealing weapons programmes and intended to restart them as soon as economic sanctions collapsed.

One did not need access to secret intelligence to reach this conclusion. Saddam was already in violation of 16 United Nations Security Council resolutions pertaining to weapons of mass destruction by the time of the 2003 invasion. He kicked inspectors out of the country on multiple occasions. He never allowed the UN access to his scientists demanded by the Security Council’s final resolution. Iraq’s dictator acted as if he had something to hide and Tony Blair believed he did.

It turned out that Blair was wrong. But this was an error, not a crime; a blunder, but not a lie.
