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

Claims that drones will soon remake warfare or international politics are unwarranted. Although almost a dozen states now possess armed drones, and more are racing to acquire them, they will not play a decisive role in interstate conflicts. Drones will rarely be “winning weapons,” because they are vulnerable to air defenses. States will, however, continue to use drones against terrorists and domestic opponents.

"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."

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.

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.
