In the decade since 9/11, much has been written about the alleged changes in the nature of insurgent and revolutionary movements. Many of these studies in fact base their arguments on an interpretation of the functioning of the global Jihadist movement. They boil down to a technical analysis of principles of insurgency and counterinsurgency, devoid of politics and ideology. The presently successful Arab Spring movements, which have eclipsed the Jihadist appeal in most of the Middle East, indeed do display some of these trends. Nevertheless, they also bear witness to the continued importance of politics and ideology. Their success is ultimately based on the mobilisation of widespread popular support through an appealing cause that taps into widespread grievances.
