Kilcullen is both a soldier and a scholar, with experience ranging from small combat unit leadership to the staff of a theater-level commander (Gen. Petraeus), and perspective drawing on service in a variety of places and types of situations. Like John Nagl (who also worked for Petraeus), this author is more able than even most effective leaders to analyze and project based on developing and likely trends in economics and geopolitics.
This book looks at the accelerating growth of megacities, especially coastal ones, and the percentage of the world's population that lives in those megacities, especially the poor, and how those changes will affect the future of warfare. Any political or military policy-maker who wants to avoid the common mistake of planning to refight the last war would do well to read LtCol. Kilcullen's books.
