A critical tool for the study of U.S. history, this volume offers an analysis of important documents and decisions in U.S. foreign policy from George Washington to Barack Obama. The study of historical primary documents provides a uniquely beneficial and insightful view into history. To that end, U.S. Foreign Policy: A Documentary and Reference Guide presents and interprets important documents from throughout U.S. history, from the administration of George Washington to that of Barack Obama. Examining U.S. foreign policy through this lens identifies the ideals of the United States during different periods, illuminates the intent behind its military actions, and reveals how each American president interpreted his moral responsibilities as leader of one of the most powerful nations in the world. Organized to allow readers to examine the historical evolution of U.S. foreign policy, the book includes treaties, speeches, and other documents that illustrate important doctrines and decisions over the more than two centuries of American history, covering all presidential doctrines to the current administration. It also highlights various phases of foreign policy, from regionalism to westward expansion, from the Cold War to a New World Order. In addition to the documents themselves, the authors provide invaluable analysis and commentary that will help students understand what the documents mean—both in the context of their time, and in terms of their broader historical significance.
