The Art of War in an Asymmetric World is a much needed work synthesizing modern thinking about war and refreshing it for the 21st century. It offers an interdisciplinary look into the human dimensions of war and the impacts of technology, globalization, and increased complexity. Moving beyond the sound bites of strategic thinking, it is a profound pondering about war, strategy, and sources of conflict. Much like Michael Handel's 1992 classic, Masters of War: Classic Strategic Thought, Zellen's new book is bound to stir debate among America's strategic thinkers.

Barry Zellen has provided a book that stretches the boundaries of our thinking on the nature of global disorder following the collapse of the bipolar world in the 1990s. As noted by Zellen, the world is today riven by a variety of clashes surrounding different aspects of modernity, globalization, disenfranchised populations, human rights, religion, and ethnicity. This work points out that war and conflict in today's world need to be understood in the context of systemic global complexity and are not attributable to a single factor. All students and scholars of strategy and conflict in the current era should take note of Zellen's important and lasting contribution to our understanding of war in the modern world.

In his fascinating new book, The Art of War in an Asymmetric World, Barry Scott Zellen breaks new theoretical ground, exploring both the theorists of disorder who emerged after the Cold War's end, and the strategists of order who responded to this new, chaotic world. While much of our world has globalized, Zellen reminds us that in the remote regions where today's wars are being waged, the world remains inherently tribal. Zellen provocatively argues only tribal order-- and not state-imposed centralized orders-- can provide us with a stable, and enduring structure of world politics, and a foundation for the return of peace. One need not share Zellen's enthusiastic embrace of tribalism to both understand and appreciate that his book initiates a much-needed debate on tribalism in the modern world.

Barry Scott Zellen's The Art of War in an Asymmetric World breaks new ground weaving together the intimate (but usually neglected) interconnections between tribal conflict and the fight against terrorism, which has been unfolding now for over a decade in some of the most remote and therefore, largely indigenous frontier regions in the world. Had our war planners read this pioneering work before entangling us in Afghanistan, we'd very likely not be in the tragic situation that we are today. This important work needs to be closely read-- particularly Zellen's concluding chapter on 'The Tribal Foundations of Order'-- at the highest levels of command now facing intractable Transnational Organized Crime, both here in the Americas and across the seas.
