" For America, Britain, and the Western powers, the rise of ISIS and the caliphate is the ultimate disaster. Whatever they intended by their invasion of Iraq in 2003 and their efforts to unseat Assad in Syria since 2011, it was not to see the creation of a jihadi state spanning northern Iraq and Syria, run by a movement a hundred times bigger and much better organized than the al-Qaeda of Osama bin Laden. The war on terror for which civil liberties have been curtailed and hundreds of billions of dollars spent has failed miserably. "
