This book offers a comprehensive examination of contemporary efforts to combat antisemitism through coordinated policy initiatives at both national and international levels. Drawing on official documents, legislative actions, and institutional reports, the book explores how governments, intergovernmental bodies, and civil society organizations are responding to the resurgence of antisemitic rhetoric, violence, and discrimination. Chapters include detailed analyses of the U.S. National Strategy to Counter Antisemitism, executive actions under multiple administrations, and congressional investigations into antisemitic influences in global institutions such as the United Nations and Latin American political movements. The book also highlights the role of domestic programs—such as the Nonprofit Security Grant Program—and cultural institutions like museums in fostering resilience and education against hate. This book serves as a resource for scholars, policymakers, and practitioners seeking to understand and strengthen the frameworks that protect Jewish communities worldwide. It underscores the urgency of a unified, strategic response to antisemitism in all its forms.
