Many people, even alleged conservatives, blame the West when it comes to explaining Islamic terrorism. If it wasnt the crusades, it was the end of World War One, when Winston Churchill and T. E. Lawrence (of Arabia), among others, carved up the map of the modern Middle East. But if the collapse of the Ottoman Empire and the creation of modern Iraq, Syria, Jordan, and Palestine (eventually Israel) were a cause of movements like ISIS, why was the region relatively quiescent after the First World War?
