Gen Shaw said the Government's approach towards Isil was fundamentally mistaken. "People are still treating this as a military problem, which is in my view to misconceive the problem," he added. "My systemic worry is that we're repeating the mistakes that we made in Afghanistan and Iraq: putting the military far too up front and centre in our response to the threat without addressing the fundamental political question and the causes. The danger is that yet again we're taking a symptomatic treatment not a causal one."
