““The war on terror for which civil liberties have been curtailed and hundreds of billions of dollars spent has failed miserably. The belief that Isis is interested only in ‘Muslim against Muslim’ struggles is another instance of wishful thinking: Isis has shown it will fight anybody who doesn’t adhere to its bigoted, puritanical and violent variant of Islam. Where Isis differs from al-Qaida is that it’s a well-run military organisation that is very careful in choosing its targets and the optimum moment to attack them.””
