The Arab Awakening augurs the return of political contestation to key Arab societies in which little more than token opposition had been tolerated. Unfolding experiments in democratisation in which Islamically-oriented parties are leading players are underway but the prospects for the consolidation of stable political systems in key counties, such as Egypt or Syria are problematic. These developments have hastened a new regional balance of power in which Saudi Arabia and its allies have sought to stem the tide of change as well as thwart the hegemonial ambitions of Iran. Persistent issues, particularly the Israel-Palestine conflict, remain unresolved and have a powerful grip on the conscience of the Arab world. Key external powers, especially the United States, confront not only stubborn familiar issues but also a host of new strategic, economic, diplomatic and military challenges.
