In June 2017, Bahrain, Egypt, Saudi Arabia, and the UAE announced a comprehensive boycott of Qatar. Diplomatic ties were severed, trade was banned, and airspace was closed. Qatari nationals were expelled from all four countries. It seemed that disaster loomed for this small Gulf nation. But not so. Instead, in an unexpected turn of events, the Qatari government deftly used its enormous wealth and extensive reserves of soft power to nullify most of the effects of what came to be known as the Rift. Edward Lynch tells the story of the Gulf Rift from start to finish. Exploring the historical and contemporary causes of the dispute, the reactions to it both regionally and globally, and the surprising end to the crisis, his work serves also to highlight the often unrecognized role of small states in international relations.
