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."

Many international peacebuilders have suggested that integrating opposing combatants into a national military after civil war helps prevent conflict from recurring. Analysis of eleven cases of post–civil war military integration, however, reveals little evidence to support this claim. Underlying political conditions, not military integration, determine whether peace endures.

Scholars have argued that acquiring nuclear weapons should allow states the luxury of exiting conventional arms races. In turn, a decreased budgetary focus on conventional arms should make possible greater spending on social welfare. The author contests this logic of nuclear substitution by examining its most likely exponent, Pakistan. As a poor, underdeveloped state, a nuclear Pakistan should have welcomed the opportunity to cease its arms race with India, and spend greater sums on its population's welfare. Instead, the article shows that Pakistan has doubled down on its pre-nuclear conventional posture, mainly because of its revisionism over Kashmir.

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.
