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

During the Trump administration, the usual ways of conducting diplomacy have been upended. Many positions in the State Department have never been filled, and meetings with foreign leaders such as Kim Jong-un and Vladimir Putin have been undertaken with little advance planning. What effect are these changes having now, and how will they affect ongoing relationships between the United States and its allies and adversaries?

"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."

Despite their disagreements, proponents of deep engagement and offshore balancing share an optimistic but unrealistic assessment regarding the durability of U.S. military dominance. China’s antiaccess/area denial strategy and conventional precision-strike capabilities are already undermining the United States’ military dominance in East Asia. The United States will need to adapt its military to meet this challenge.

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.

"Iran has always been a major power in that region. Under Saddam however, Iran and Iraq were bitter enemies who fought a long war and were strongly opposed to one another. There was almost a rough balance of power between the two countries. By reducing Iraq's power and by allowing the Shia to become the dominant political force in Iraq, the US removed the main country balancing Iran, and helped bring to power a government that has at least some sympathies and links to Iran. So, Iran is by far the main strategic beneficiary of the Iraq War, which made it even more difficult for the US and its allies to deal with the country."

"This article first considers the ways in which experimental psychology and psychoanalysis hastened the obsolescence of ideas about the so-called 'primitive mind' and, in some cases, served the purposes of overtly anti-colonial politics. It then surveys the history of intelligence testing in the British Empire, which originated in the aftermath of the First World War, expanded in scale after the Second, and ultimately contributed to post-colonial development. Finally, it asks how far the case of psychology puts the very concept of 'colonial science' into question."
