More than 2,000 years ago the Chinese strategist Sun Tzu advised us to know our enemies. The question has always been how. In A Sense of the Enemy, the historian Zachary Shore demonstrates that leaders can best understand an opponent not simply from his pattern of past behavior, but from his behavior at pattern breaks. Meaningful pattern breaks occur during dramatic deviations from the routine, when the enemy imposes costs upon himself.
