The single greatest national security question currently facing the U.S. National Command Authority is how best to counter violent extremism. The National Command Authority has four broad strategies through which it may employ military forces to counter violent extremism: counterinsurgency, counterterrorism, support to insurgency, and antiterrorism. The Long War is anticipated to continue for decades, perhaps generations. Thus, it is imperative to select the best strategy or strategies for employing military forces. Based on historical lessons in combating terrorism, the best strategy is efficient and sustainable and avoids overreacting, acting incompetently, or appearing to be either over reactive or incompetent. Counterinsurgency is neither efficient nor sustainable from a military, economic, or political perspective. It is a high risk strategy because it is a large, highly visible undertaking through which the United States may easily overreact, act incompetently, or be perceived as overreacting or being incompetent. Counterterrorism, support to insurgency, and antiterrorism are each both efficient and sustainable from a military and economic perspective. These three strategies each have inherent political concerns, hazards, or constraints. However it is considerably less likely that the United States will overreact, behave incompetently, or be perceived as overreacting or being incompetent through engaging in one or more of these three strategies than by engaging in counterinsurgency. Support to insurgencies is economically and militarily efficient and sustainable, but it carries substantial political risks. Thus, an overall strategy combining counterterrorism and antiterrorism is the best means of employing military forces to counter violent extremism.

Since September 2001, the United States has waged what the government initially called the global war on terrorism (GWOT). Beginning in late 2005 and early 2006, the term Long War began to appear in U.S. security documents such as the National Security Council's National Strategy for Victory in Iraq and in statements by the U.S. Secretary of Defense and the Chairman of the JCS. The description Long War—unlimited in time and space and continuing for decades—is closer to reality and more useful than GWOT. Colonel Robert Cassidy argues that this protracted struggle is more correctly viewed as a global insurgency and counterinsurgency. Al Qaeda and its affiliates, he maintains, comprise a novel and evolving form of networked insurgents who operate globally, harnessing the advantages of globalization and the information age. They employ terrorism as a tactic, subsuming terror within their overarching aim of undermining the Western-dominated system of states. Placing the war against al Qaeda and its allied groups and organizations in the context of a global insurgency has vital implications for doctrine, interagency coordination, and military cultural change-all reviewed in this important work. Cassidy combines the foremost maxims of the most prominent Western philosopher of war and the most renowned Eastern philosopher of war to arrive at a threefold theme: know the enemy, know yourself, and know what kind of war you are embarking upon. To help readers arrive at that understanding, he first offers a distilled analysis of al Qaeda and its associated networks, with a particular focus on ideology and culture. In subsequent chapters, he elucidates the challenges big powers face when they prosecute counterinsurgencies, using historical examples from Russian, American, British, and French counterinsurgent wars before 2001. The book concludes with recommendations for the integration and command and control of indigenous forces and other agencies.

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.

Most policymakers see counterinsurgency and counternarcotics policy as two sides of the same coin. Stop the flow of drug money, the logic goes, and the insurgency will wither away. But the conventional wisdom is dangerously wrongheaded, as Vanda Felbab-Brown argues in Shooting Up. Counternarcotics campaigns, particularly those focused on eradication, typically fail to bankrupt belligerent groups that rely on the drug trade for financing. Worse, they actually strengthen insurgents by increasing their legitimacy and popular support. Felbab-Brown, a leading expert on drug interdiction efforts and counterinsurgency, draws on interviews and fieldwork in some of the world's most dangerous regions to explain how belligerent groups have become involved in drug trafficking and related activities, including kidnapping, extortion, and smuggling. Shooting Up shows vividly how powerful guerrilla and terrorist organizations — including Peru's Shining Path, the FARC and the paramilitaries in Colombia, and the Taliban in Afghanistan — have learned to exploit illicit markets. In addition, the author explores the interaction between insurgent groups and illicit economies in frequently overlooked settings, such as Northern Ireland, Turkey, and Burma. While aggressive efforts to suppress the drug trade typically backfire, Shooting Up shows that a laissez-faire policy toward illicit crop cultivation can reduce support for the belligerents and, critically, increase cooperation with government intelligence gathering. When combined with interdiction targeting major traffickers, this strategy gives policymakers a better chance of winning both the war against the insurgents and the war on drugs.

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.
