“At a time when too many well-motivated leftists are trapped in what Michael Walzer characterizes as a complacent 'default position,' his case for leftist foreign-policy activism, buttressed by serious inquiry into a practical program of action, represents a significant accomplishment.”—David Goldfischer, Korbel School of International Studies, University of Denver"Michael Walzer addresses an urgent issue that has not received the attention it deserves—the complex attitudes of American left-wing intellectuals toward American foreign policy in particular and American engagement with international affairs in general.  He is unafraid to criticize the American left for parochialism, insularity, and even isolationism. This lucid, passionate book is bound to stimulate vigorous debate."—Michael Ignatieff, President of Central European University, Budapest"Michael Walzer may be America's most challenging philosopher of liberalism today. We are indeed fortunate that his essays are written with so much passion, eloquence, and precision that his readers may rest assured to find themselves in edifying, and often inspiring, company."—Eric Alterman, columnist, The Nation"Michael Walzer’s search for a sensible left-wing approach to international wrongs is one of the compelling ventures in our political-philosophical life, and it is beautifully on display in these cogent and challenging essays."—Todd Gitlin, author of The Sixties: Years of Hope, Days of Rage"For those of us who grew up on Just and Unjust Wars, Michael Walzer is a beacon of honest, engaged debate. His call for a leftist foreign policy based on decency and humanity is a vitally important corrective to so many of his comrades who have lost their bearings in and on global politics."—Anne-Marie Slaughter, President and CEO, New America
