George W. Bush's favorite neoliberal from the UK does some excruciating moral contortions to absolve himself of any responsibility (and blame) for the current chaos in Iraq.

Tony Blair has strongly rejected claims that the 2003 US-UK invasion of Iraq was to blame for the current crisis gripping the country, pointing the finger instead firmly at the Maliki government and the war in Syria.

In a passionate essay published on his website, the former prime minister said it was a "bizarre" reading of the situation to argue that the US-British invasion of Iraq had allowed the growth of Sunni jihadist groups such as the Islamic State in Iraq and the Levant (Isis), whose fighters have swept through towns and cities north and west of Baghdad over the past week.

"We have to liberate ourselves from the notion that 'we' have caused this. We haven't. We can argue as to whether our policies at points have helped or not: and whether action or inaction is the best policy. But the fundamental cause of the crisis lies within the region not outside it.

"We have to put aside the differences of the past and act now to save the future," says Blair, adding that force may be necessary. "Where the extremists are fighting, they have to be countered hard, with force."

And here is part of the essay on Blair's website:

Consider the post 2011 Arab uprisings. Put into the equation the counterfactual – that Saddam and his two sons would be running Iraq in 2011 when the uprisings began. Is it seriously being said that the revolution sweeping the Arab world would have hit Tunisia, Libya, Egypt, Yemen, Bahrain, Syria, to say nothing of the smaller upheavals all over the region, but miraculously Iraq, under the most brutal and tyrannical of all the regimes, would have been an oasis of calm?

Easily the most likely scenario is that Iraq would have been engulfed by precisely the same convulsion. Take the hypothesis further. The most likely response of Saddam would have been to fight to stay in power. Here we would have a Sunni leader trying to retain power in the face of a Shia revolt. Imagine the consequences. Next door in Syria a Shia backed minority would be clinging to power trying to stop a Sunni majority insurgency. In Iraq the opposite would be the case. The risk would have been of a full blown sectarian war across the region, with States not fighting by proxy, but with national armies.

So it is a bizarre reading of the cauldron that is the Middle East today, to claim that but for the removal of Saddam, we would not have a crisis.

And it is here that if we want the right policy for the future, we have to learn properly the lessons not just of Iraq in 2003 but of the Arab uprisings from 2011 onwards.
