Stephen Walt argues for a return to a realism-based U.S. grand strategy.

The fall of Aleppo is a human catastrophe. It’s also a demonstration of the perils of choosing the middle course in a military conflict. Sometimes it’s possible to talk and fight at the same time. But in Syria, the U.S. decision to pursue a dual-track, halfway approach made the mayhem worse.

"For nearly a century, in short, offshore balancing prevented the emergence of dangerous regional hegemons and pre­served a global balance of power that enhanced American security. Tellingly, when U.S. policymakers deviated from that strategy—as they did in Vietnam, where the United States had no vital interests—the result was a costly failure."

Blood revenge is a crucial yet understudied contributor to many insurgencies and civil wars. Interviews with participants in and witnesses to the First and Second Chechen Wars reveal how a desire to avenge dead or injured relatives drove many Chechens to join insurgent groups.

Many academics and policymakers argue that the removal of leaders is an effective strategy in combating terrorism. Leadership decapitation is not always successful, however. A theory of organizational resilience explains why some terrorist organizations survive decapitation. Application of this theoretical model to the case of al-Qaida reveals that the deaths of Osama bin Laden and other high level al-Qaida operatives are unlikely to cause significant organizational decline.

Existing scholarship assumes that transnational insurgents strengthen domestic rebels. Analysis of transnational insurgents’ participation in the Chechen wars, however, reveals that foreign fighters can weaken a domestic opposition movement by introducing goals and tactics that divide the movement and alienate the local community. To avoid this outcome, domestic resistance leaders must adapt the foreigners’ ideas to the local context.

While the threat of "resource wars" over possession of oil reserves is often exaggerated, between one-quarter and one-half of interstate wars since 1973 have been connected to one or more of eight distinct oil-related causal mechanisms. Understanding these mechanisms can help policymakers design grand strategy and allocate military resources.

U.S. scholars and policymakers commonly worry that a lack of "energy security" hurts U.S. national security, yet few have analyzed the links between states' energy requirements and the probability of military conflict. An investigation of these links identifies threats to U.S. national security flowing from other countries' consumption of oil, rather than just U.S. consumption. Furthermore, while many of the security threats associated with Persian Gulf oil have decreased, new oil-driven dangers are emerging in Northeast Asia.
