We could defeat Islamic State within a year. I know because I fought them

The brutal rise of the so-called Islamic State took everybody by surprise. I can remember sitting at my desk in London wondering who these people were and where they had come from. Isil forced themselves onto the world stage when they took Mosel and began their relentless march across Syria and Iraq. Britain and America were totally unprepared for the uncontained explosion of violence across the Middle East.
