Leaders, writes Henry Kissinger in this compelling book, think and act at the intersection of two axes: the first, between the past and the future; the second between the abiding values and aspirations of those they lead. They must balance what they know, which is necessarily drawn from the past, with what they intuit about the future, which is inherently conjectural and uncertain. It is this intuitive grasp of direction that enables leaders to set objectives and lay down a strategy.

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'.
