A Senior Counterinsurgency Advisor to General David Petraeus, Kilcullen's vision of war dramatically influenced America's decision to rethink its military strategy in Iraq. Now, Kilcullen provides a remarkably fresh perspective on the War on Terror.

A leading expert on counterinsurgency and counterterrorism offers a comprehensive theory of "competitive control" that will apply to the future of conflict in a world of explosive population growth, increased urbanization, the movement of population centers to the coasts, and global connective networks.

David Kilcullen is one of the world's most influential experts on counterinsurgency and modern warfare, a ground-breaking theorist whose ideas "are revolutionizing military thinking throughout the west" (Washington Post). Indeed, his vision of modern warfare powerfully influenced the United States' decision to rethink its military strategy in Iraq and implement "the Surge," now recognized as a dramatic success. In Counterinsurgency, Kilcullen brings together his most salient writings on this vitally important topic. Here is a picture of modern warfare by someone who has had his boots on the ground in some of today's worst trouble spots-including Iraq and Afghanistan-and who has been studying counterinsurgency since 1985. Filled with down-to-earth, common-sense insights, this book is the definitive account of counterinsurgency, indispensable for all those interested in making sense of our world in an age of terror.

Just a few years ago, people spoke of the US as a hyperpower-a titan stalking the world stage with more relative power than any empire in history. Yet as early as 1993, newly-appointed CIA director James Woolsey pointed out that although Western powers had "slain a large dragon" by defeating the Soviet Union in the Cold War, they now faced a "bewildering variety of poisonous snakes." In The Dragons and the Snakes, the eminent soldier-scholar David Kilcullen asks how, and what, opponents of the West have learned during the last quarter-century of conflict. Applying a combination of evolutionary theory and detailed field observation, he explains what happened to the "snakes"-non-state threats including terrorists and guerrillas-and the "dragons"-state-based competitors such as Russia and China. He explores how enemies learn under conditions of conflict, and examines how Western dominance over a very particular, narrowly-defined form of warfare since the Cold War has created a fitness landscape that forces adversaries to adapt in ways that present serious new challenges to America and its allies. Within the world's contemporary conflict zones, Kilcullen argues, state and non-state threats have increasingly come to resemble each other, with states adopting non-state techniques and non-state actors now able to access levels of precision and lethal weapon systems once only available to governments. A counterintuitive look at this new, vastly more complex environment, The Dragons and the Snakes will not only reshape our understanding of the West's enemies' capabilities, but will also show how we can respond given the increasing limits on US power.

Armies are invariably accused of preparing to fight the last war. Nagl examines how armies learn during the course of conflicts for which they are initially unprepared in organization, training, and mindset. He compares the development of counterinsurgency doctrine and practice in the Malayan Emergency from 1948-1960 with that developed in the Vietnam Conflict from 1950-1975, through use of archival sources and interviews with participants in both conflicts. In examining these two events, he argues that organizational culture is the key variable in determining the success or failure of attempts to adapt to changing circumstances. Differences in organizational culture is the primary reason why the British Army learned to conduct counterinsurgency in Malaya while the American Army failed to learn in Vietnam. The American Army resisted any true attempt to learn how to fight an insurgency during the course of the Vietnam Conflict, preferring to treat the war as a conventional conflict in the tradition of the Korean War or World War II. The British Army, because of its traditional role as a colonial police force and the organizational characteristics that its history and the national culture created, was better able to quickly learn and apply the lessons of counterinsurgency during the course of the Malayan Emergency. This is the first study to apply organizational learning theory to cases in which armies were engaged in actual combat.

In 2014, a resurgent and bellicose Russia took over Crimea and fueled a civil war in Eastern Ukraine; post-Saddam Iraq lost a third of its territory to an army of hyper-violent millennialists; and the peace process in Israel seemed to completely collapse. In short, the post-Cold War security order that the US had constructed after 1991 seemed to be coming apart at the seams. David Kilcullen was one of the architects of America's strategy in the late phases of the second Gulf War, and he has also spent time in Afghanistan and other hotspots. In Blood Year, he provides a wide-angle view of the current situation in the Middle East and analyzes how America and the West ended up in such dire circumstances. Kilcullen lays much of the blame on Bush's initial decision to invade Iraq (which had negative secondary effects in Afghanistan), but also takes Obama to task for simply withdrawing and adopting a "leading from behind" strategy. As events have proven, Kilcullen contends, withdrawal was a fundamentally misguided plan. The U.S. had uncorked the genie, and it had a responsibility to at least attempt to keep it under control. Instead, the U.S. is at a point where administration officials state that the losses of Ramadi and Palmyra are manageable setbacks. Kilcullen argues that the U.S. needs to re-engage in the region, whether it wants to or not, because it is largely responsible for the situation that is now unfolding. Blood Year is an essential read for anyone interested in understanding not only why the region that the U.S. invaded a dozen years ago has collapsed into utter chaos, but also what the U.S. can do to alleviate the grim situation.

As fitting for the 21st century as von Clausewitz's "On War" was in its own time, "Invisible Armies" is a complete global history of guerrilla uprisings through the ages.
