In Leadership, Kissinger analyses the lives of six extraordinary leaders through the distinctive strategies of statecraft which he believes they embodied. After the Second World War, Konrad Adenauer brought defeated and morally bankrupt Germany back into the community of nations by what Kissinger calls 'the strategy of humility'. Charles de Gaulle set France beside the victorious Allies and renewed its historic grandeur by 'the strategy of will'. During the Cold War, Richard Nixon gave geostrategic advantage to the United States by 'the strategy of equilibrium'. After twenty-five years of conflict, Anwar Sadat brought a vision of peace to the Middle East by a 'strategy of transcendence'. Against the odds, Lee Kwan Yew created a powerhouse city-state, Singapore, by 'the strategy of excellence'. Although when she came to power Britain was known as 'the sick man of Europe', Margaret Thatcher renewed her country's morale and international position by 'the strategy of conviction'.

To each of these studies, Kissinger brings historical perception, public experience and - because he knew each of their subjects, and participated in many of the events he describes - personal knowledge. The book is enriched by insights and judgements such as only he could make, and concludes with his reflections on world order and the indispensability of leadership today.
