Book excerpt: U.S. foreign relations in the Middle East has remained crucial through many decades and the complications facing the United States in the Middle East have become even more acute. While the United States downgraded its military operations in Iraq, that country failed to achieve a stable, democratic footing and instead experienced schism and civil strife. Israeli-Palestinian disputes over land, the status of refugees, and control of Jerusalem intensified, and international conflicts between Arab states and Israel escalated for the first time since the 1980s. The Arab Spring protest movements of 2011 and after ignited political turmoil across the region, leading to revolutionary change in several states and triggering persistent unrest and violence in Libya, Egypt, Tunisia, Yemen, Syria, and Iraq. During the recent decade, in short, the Middle East has become the most unstable, dangerous, and complicated region of the world and the United States remains near the center of the maelstrom. This second edition of Historical Dictionary of United States-Middle East Relations contains a chronology, an introduction, appendixes, and an extensive bibliography. The dictionary section has over 300 cross-referenced entries on national leaders, non-governmental organizations, policy initiatives, and armed conflicts, as well as entries on such topics as intelligence, immigration, and weapons of mass destruction. This book is an excellent access point for students, researchers, and anyone wanting to know more about the US and Middle East Relations.
