I found the psychological insights to historical military events to be interesting. In a previous incarnation I taught management "science" and the psychological failures/flaws of people like General Lee, Napoleon, Hitler, Churchill, etc. are found in lesser beings in board rooms around the world. The insights in this book would be useful to a student of business and political as well as military leadership. The authors, one a historian and the other a psychologist, and both academics, elected to write about military conflicts of global proportions in order to make their point. This is understandable. The academic tendencies tend to sound a little like a college text book at times (which this may be the case) and this gets a little ponderous at times. But, it is worth sticking with it because the central theme is a common flaw in business, education, government, and every other endeavor where you have people leading other people. If you hold any kind of leadership position you should read this book. I wish I had this book when I was teaching this stuff. It would have made things a little more interesting.
