This book examines the foreign policy stances of global, regional, and European actors toward the Israeli-Palestinian conflict following the critical turning point of October 7, 2023. Drawing on fifteen original case studies across four continents, it offers a structured comparative analysis of the United States, the United Kingdom, China, and Russia; regional actors directly affected by the crisis - Türkiye, Egypt, Iran, Saudi Arabia, and Qatar; two non-regional Muslim-majority states, Azerbaijan and Indonesia; and four EU member states - France, Germany, Spain, and Ireland. The volume explores how October 7 shaped state behaviors through various pathways, highlighting major mechanisms of foreign policy adjustment such as identity reinforcement, rhetorical alignment, and genuine rupture. Each chapter analyzes how states redefine their strategic interests, historical legacies, and commitments to international law in the post-October 7 global order. This timely volume is an essential reference for scholars, students, and policymakers in International Relations and Middle Eastern studies.
