With their homelands at war, can Diasporas lead the way to peace, or do they present an obstacle to conflict resolution, nurturing hate far away from those who actually fall victim to violence? And which of these roles do the Jewish and Palestinian diaspora communities play in the Israeli-Palestinian conflict? Particularly since the Oslo peace process, the search for a solution to the Israeli-Palestinian conflict has been strongly contested among Jewish and Arab/Palestinian Organizations in the United States. Through an analysis of the activities of Arab-Palestinian and Jewish organizations on behalf of and towards their conflict-ridden homelands, Diasporic Activism in the Israeli-Palestinian Conflict provides both a detailed picture of diasporic activism in the Middle East as well as advancing theory-building on the roles of diasporas in helping or hindering peace. Drawing on research into (transnational) social movements, diaspora studies and constructivist International Relations theory, this book retraces how this process of diversification occurred, and explains why neither the Jewish nor the Arab Diaspora community hold a unified position in the Israeli-Palestinian conflict, but are each comprised of both hawks and doves. Combining theoretical depth and practical orientation, this book is a key resource for those working in the fields of Middle Eastern studies, Peace and Conflict Studies and Diapora Studies, as well as specialists on the ground in Israel/Palestine and other conflict settings in which Diaspora communities play a prominent role.
