This book analyzes the Israeli-Palestinian conflict through three alternative lenses. Drawing on different international relations and foreign policy perspectives, it examines two central issues in the history of this conflict: the dilemma of partition in 1947, and the acceptance of the principle of a two-state solution at Oslo in 1993. It offers a multilevel insight into the determinants of this conflict, specifying what aspects of it can be explained by cognitive, domestic and systemic factors. By looking at the same cases of decision, but from different angles, it shows how different theoretical perspectives produce different explanations for the same historical event.
