This is an extraordinary book, one that braids together two through lines in the long and distinguished career of former Secretary of State Henry Kissinger. The first is grand strategy: No practical geopolitical thinker has more assuredly mastered the way the modern global system works or how nations use the tools of statecraft to bend an often-resistant world to their will. But Mr. Kissinger is also an astute observer of the personal element in strategy-the art and science of leadership, or how, on the executive level, "decisions [are] made, trust earned, promises kept, a way forward proposed." In Leadership he presents a fascinating set of historical case studies and political biographies that blend the dance and the dancer, seamlessly. ... In doing so, he lays out a set of graspable tools that leaders can use effectively today. ... Kissinger puts a high premium on a deep and considered knowledge of history, coupled with a strength of inner character.
