Now, more than ever, Britain must stay in Iraq

William Shawcross denounces those who say we must stand firm in Afghanistan but flee the country we liberated from Saddam Hussein. The US ‘surge’ is beginning to work, and Gordon Brown must grasp that the war against Islamism is indivisible

The new comfort zone for many politicians and leader-writers appears to be the notion that if Britain withdraws its troops from Iraq and sends all the freed-up forces to Afghanistan, then all will be well. Siren voices are insisting that honour would be satisfied by such a move and we would still be pulling our weight in what Gordon Brown refuses to call ‘the war on terror’ or ‘the war against Islamist extremism’. Afghanistan, say those voices, is the crucial place to be engaging al-Qa’eda. Iraq is a sideshow.

This is no comfort zone at all. The war against Islamist extremism is indivisible. ‘The thought that Afghanistan is somehow a more righteous war is absurd,’ General Jack Keane told me this week.
