The Middle East is a center of ceaseless global attention. Since 2011, the long awaited and much celebrated Arab Spring uprisings portended a major shift in the politics of the Arab World. Notably, a number of Arab states witnessed institutional and constitutional shifts that put them on the path of transition to liberalization and democracy. Nevertheless, the Arab Spring followed a violent and unpredictable course. Although its events marked a break in the continuity of authoritarian dominance, most of its changes have not ultimately proved to be turning points in democratic development. The Arab Spring phenomenon witnessed a set of uprisings and even would-be-revolutions, but no great revolutionary change. Edited by Professor Philipp Amour of prestigious Sakarya University, this volume presents the work of numerous distinguished scholars, including many native to the region, who explore the fascinating variety of factors behind the rise and fall of the Arab Spring. As they establish, regional polarization and rivalries are the principal accompanying phenomena and side effects of the Arab Spring, and they will demand the world's attention for decades to come. Power dynamics between and among regional great powers have invited proactive, protracted, and very topical military and diplomatic involvement in domestic and regional politics. Some of these interventions will uphold the status quo, while others seem more likely to modify it for the powers' strategic advantage. Authored by leading world experts in Middle Eastern politics, this collection explores foreign and security policy of regional great powers such as Iran, Egypt, Saudi Arabia, Turkey, the United Arab Emirates, and their roles in the construction of the new Middle East.
