"In times like these, it is important to appreciate the role that moral reasoning should play in foreign policy. This is especially true in a democracy, where sustaining global involvement requires support from citizens. Joe Nye is one of our foremost and engaging analysts of American diplomacy, and in this book he provides a clear-eyed guide for reengaging our moral compass." -- Walter Isaacson, Distinguished Fellow and Former CEO, Aspen Institute, and Professor of History, Tulane University

"From the doyen of US foreign policy thinkers, a powerful warning against domestic populist politics, which not only narrow our moral vision but defeat US purposes around the world." -- O.A. Westad, Yale University

"With characteristic insight and precision, Joseph Nye raises tough questions of how much ethics should shape a nation's foreign policy, provides a sweeping review of how past presidents have embraced or rejected ethical imperatives, and constructs a helpful scorecard for judging future presidents. This book takes on even greater significance as a growing number of nations-led by the U.S.-nakedly put self interest first." -- David Gergen, CNN Senior Political Analyst, and Founding Director, Harvard Kennedy School Center for Public Leadership

"In Do Morals Matter? Joseph S. Nye argues persuasively that in foreign policy, good intentions must be accompanied by the use of appropriate means that generate beneficial consequences. His astute analysis of American presidents since World War II demonstrates that 'contextual intelligence' is crucial for moral principles to yield good results." -- Robert O. Keohane, Princeton University

"A lucid, thoughtful and original examination of the role morality plays as American presidents shape their foreign policy. As Professor Nye shows convincingly in this highly readable book, leaders and citizens alike make assumptions, decisions and judgments which reflect their own views about what is good and bad. Yet again he has contributed much to our better understanding of international relations." -- Margaret MacMillan, Emeritus Professor of International History, University of Oxford
