What makes a great leader? In Supreme Command, Cohen examines this question by studying four of the most influential and effective civilian leaders of all time: Abraham Lincoln of the US, Georges Clemenceau of France, Winston Churchill of Great Britain, and David Ben-Gurion of Israel. Cohen’s case studies offer a glimpse into the best cases of when “civil” came first in civil-military relations. Not only does Supreme Command give us new insights into well-known Western leaders like Lincoln and Churchill, but Cohen sketches telling portraits of leaders that deserve more attention, like Clemenceau and Ben-Gurion. A unique combination of biography and civil-military relations.
