Leading scholars and policymakers explore how history influences foreign policy and offer insights on how the study of the past can more usefully serve the present.History, with its insights, analogies, and narratives, is central to the ways that the United States interacts with the world. Historians and policymakers, however, rarely engage one another as effectively or fruitfully as they might. This book bridges that divide, bringing together leading scholars and policymakers to address the essential questions surrounding the history-policy relationship including Mark Lawrence on the numerous, and often contradictory, historical lessons that American observers have drawn from the Vietnam War; H. W. Brands on the role of analogies in U.S. policy during the Persian Gulf crisis and war of 1990-91; and Jeremi Suri on Henry Kissinger's powerful use of history.
