The Wall Between is a book about the wall that exists between Jewish and Palestinian communities in the Diaspora. Distrust, enmity, and hate are common currencies. They manifest at university campuses, schools and school boards, at political events, on social media, and in academic circles. For Jews, Israel must exist; for Palestinians, the historic injustice being committed since 1948 must be reversed. Neither wants to know why the Other cannot budge on these issues. The wall is up. These responses emanate, primarily, from the two 'metanarratives' of Jews and Palestinians: the Holocaust and the Nakba. Virtually every response to the struggle, from a member of either community, can be traced back to issues of identity, trauma, and victimhood as they relate to their respective metanarrative. This book examines the role that propaganda and disinformation play in cementing trauma-induced fears for the purpose of making the task of humanizing and acknowledging the Other not just difficult, but almost inconceivable. The authors utilize recent cognitive research on the psychological and social barriers that keep Jews and Palestinians in their camps, walled off from each other. They present a clear way through, one that is justice-centered, rather than trauma-and propaganda-driven. The authors have lived these principles and traveled this journey, away from their tribal traumas, through embracing the principles of justice. They insist that commitment to the Other means grappling with seemingly incompatible narratives until shared values are decided and acted upon. This book is a call to justice that challenges the status quo of Zionism while at the same time dealing directly with the complex histories that have created the situation today. The book is both realistic and hopeful - a guide for anyone who is open to new possibilities within the Israel-Palestine discourse in the West.
