“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.”
