Book excerpt: The sponsoring of the Muslim Brotherhood by the Emirate of Qatar and its influential satellite channel, Al Jazeera, contributed to shaping the prelude to the uprising. But the explosion's deep roots, asserts Achcar, mean that what happened until now is but the beginning of a revolutionary process likely to extend for many more years to come. The author identifies the actors and dynamics of the revolutionary process: the role of various social and political movements, the emergence of young actors making intensive use of new information and communication technologies, and the nature of power elites and existing state apparatuses that determine different conditions for regime overthrow in each case. Drawing a balance-sheet of the uprising in the countries that have been most affected by it until now, i.e. Tunisia, Egypt, Yemen, Bahrain, Libya and Syria, Achcar sheds special light on the nature and role of the movements that use Islam as a political banner.
