U.S. Foreign Policy and National Security: Chronology and Index for the 20th Century provides a unique compilation of data never before combined in a single volume. Key events and policy meetings are arranged in order by presidential administration, from the McKinley administration to that of President Obama. Each section begins with a concise list of policymakers, including Cabinet-level officials, members of the National Security Council, and senior ranks of the Department of State and Department of Defense, supplemented with bibliographic data. The bulk of each chapter is comprised of detailed lists of meetings of the president of the United States with key advisors and foreign dignitaries. These meetings include international conferences, meetings between the president and foreign leaders, meetings of the joint chiefs of staff in World War II, and meetings of the National Security Council since its creation in 1947. This unprecedented guide will be invaluable to researchers and, indeed, to anyone interested in the decisions that determined the course of U.S. history.
