In dealing with the intricacies of human nature, society, politics, ethics, theology, racism, and international relations, Reinhold Niebuhr, the teacher, preacher, philosopher, social critic and ethicist, may have been the most important American thinker of the twentieth century. This book distils Niebuhr's disparate and heretofore difficult-to-access work on international relations into one volume. Drawing from the well-springs of Niebuhr's Christian social thought,
the volume explores the depths of Niebuhr's views on human nature, collective life, U.S. foreign policy, Just War Theory, Cold War era containment, globalization, and the U.N. It then applies his approach to contemporary foreign policy issues such as the 2003 Iraq War, the Responsibility to Protect,
and the rise of China.
