This book examines trends in American public opinion about Israel in over 75 years, from 1944 to 2019. Analyzing data from hundreds of surveys in jargon-free writing, the authors show that public support for Israel has seen a dramatic shift toward increased division between partisan and select demographic groups, elaborating on the implications that this important change may have for the countries’ special relationship. Scholars and students of American foreign policy, public opinion, Middle East politics and international relations, as well as policy analysts, policymakers, journalists and anyone interested in American policy toward Israel, will want to read this book.
