Here's what he said (courtesy of the BBC website):
"Very few observers actually highlighted the scale of the violence that we could face. I think about the only person in my recollection who got it right was President Mubarak who warned of unleashing 100 Bin Ladens."
He said undefeated elements of the Ba'athist regime combined with international terrorists and Iran-backed "Shia extremists" had created an "onslaught of violence that was not thought through by any observer".
Sir John said: "I think frankly, had we known the scale of violence, it might well have led to second thoughts about the entire project and we could certainly have mitigated some aspects of it had we had a clearer appreciation of it in advance."
But he said it was not "reasonable" to assume the violence should have been predicted, as it was an "unprecedented scenario".
So, according to the head of MI6 -- who also happens to be a former foreign affairs adviser to Tony Blair -- it was not "reasonable" to assume that the violence should have been foreseen, and only President Mubarak of Egypt predicted the manner in which the invasion of Iraq would exacerbate the threat of al-Qaeda-related terrorism, inside and outside Iraq.
Is he lying, suffering from amnesia or just plain ignorant? It must be one of the three, because I can assure Sir John that countless intelligence reports, terrorism experts, diplomats, politicians and pundits, at home and abroad, warned that invading Iraq wouldn't be the "cakewalk" predicted by the neocons, and that it would only radicalise Muslims across the globe, destabilise the country and the region, and provide new opportunities for jihadists to attack western troops on a Muslim battlefield.
Do you want a few examples?
1) Here's the American Academy of Arts, in its report War With Iraq: Costs, Consequences, and Alternatives, published in 2002:
Another concern is that American occupation forces in Iraq, perhaps for a protracted period of time, will be vulnerable to the violence and instability that could ensue once Saddam's regime has collapsed . . . Considerable recent experience, from US Marines bombed in Lebanon to US military personnel murdered in Kuwait, suggests that US forces in dangerous circumstances are prone to be victimised by terrorist attacks.
Al-Qaeda and its affiliates would find American forces in a post-Hussein Iraq to be an irresistible target . . . Those who today blow up French tankers off Yemen or bars in Bali will soon be picking off GIs in Basra.
3) Here's the former CIA official Paul Pillar's view, as reported in the Washington Post in 2006:
Pillar describes for the first time that the intelligence community did assessments before the invasion that, he wrote, indicated a postwar Iraq "would not provide fertile ground for democracy" and would need "a Marshall Plan-type effort" to restore its economy despite its oil revenue. It also foresaw Sunnis and Shiites fighting for power.
Pillar wrote that the intelligence community "anticipated that a foreign occupying force would itself be the target of resentment and attacks -- including guerrilla warfare -- unless it established security and put Iraq on the road to prosperity in the first few weeks or months after the fall of Saddam".
In an interview, Pillar said the pre-war assessments "were not crystal-balling, but in them we were laying out the challenges that would face us depending on decisions that were made".
4) Here's an account in the Independent of how six of Britain's leading experts on Iraq and the Middle East briefed Tony Blair on the potentially dangerous consequences of invading Iraq, back in 2002, in Downing Street:
Over the next hour and a half the experts sought to take Mr Blair and his senior colleagues through a number of possible post-invasion scenarios, ranging from simply replacing Saddam with another dictator, though one sympathetic to the west, to a messy slide into civil war and fragmentation of the country along ethnic, religious and tribal lines.
* "Ethnic, tribal and religious schisms could produce civil war or fracture the state after Saddam is deposed."
* " . . . a small number of terrorists could reasonably choose to attack US forces in the hope that they can incite an action-reaction cycle that will enhance their cause and increase their numbers."
* "This ongoing media attention to suicide bombing suggests that any future Iraqi terrorist leaders could have this tactic at the forefront of their minds."
* "After the first year, the possibility of a serious uprising may increase, should severe disillusionment set in and Iraqis begin to draw parallels between US actions and historical examples of western imperialism."
* "Even the most scrupulous effort at fairness can alienate various tribes and ethnicities from the occupation forces and cause them to respond to occupation policies as a group. This discontent could fuel mass action or even an uprising."
So Sir John Sawers is wrong -- not that the establishment worthies on the Chilcot inquiry panel seem to have noticed. (By the way, isn't it time they hired a proper QC to help them out with their feeble questioning?)
It's difficult to disagree with the verdict of Professor George Joffe, one of the "experts" called in to see Blair in 2002: "What has happened in Iraq was predictable and was predicted . . ."
