Examines the perspectives of Democrats and Republicans on dozens of major foreign policy issues of the 21st century, illuminating both areas of consensus and issues where partisan divisions are wide.From the earliest days of the republic through the Cold War and to the present day, American foreign policy has been colored by the beliefs and values of America's major political parties. Surveying the breadth and depth of partisan divisions on a variety of key foreign policy issues yields a better understanding of how partisanship has helped define U.S. leadership in the modern era.This book treats 38 individual foreign policy issues, each chosen for its timeliness and importance to American interests in the 21st century. For example, readers will learn about the partisan feelings regarding U.S. foreign policy toward Cuba that surfaced in the wake of President Obama's visit to Cuba in 2016 and his decision to resume diplomatic relations. These feelings serve as an excellent example of both partisan and intergovernmental divisions on a key U.S. foreign policy issue. Each entry contains an historical overview that will quickly bring readers "up to speed" on the issue, followed by an authoritative survey of positions and statements held by presidents, key leaders of Congress, and other important voices in both the Republican and Democratic parties. The book will serve as a vital and highly accessible reference for anyone-undergraduate university students, advanced high school students, and general readers-who needs a one-stop source for information about partisanship and U.S. foreign policy.
