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

"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."

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."

States use wedge strategies to prevent hostile alliances from forming or to dis­perse those that have formed. These strategies can cause power alignments that are otherwise unlikely to occur, and thus have significant consequences for international politics. How do such strategies work and what conditions promote their success? The wedge strategies that are likely to have significant effects use selective accommodation—concessions, compensations, and other inducements—to detach and neutralize potential adversaries. These kinds of strategies play important roles in the statecraft of both defensive and offensive powers. Defenders use selective accommodation to balance against a primary threat by neutralizing lesser ones that might ally with it. Expansionists use se­lective accommodation to prevent or break up blocking coalitions, isolating opposing states by inducing potential balancers to buck-pass, bandwagon, or hide. Two cases—Great Britain’s defensive attempts to accommodate Italy in the late 1930s and Germany’s offensive efforts to accommodate the Soviet Union in 1939—help to demonstrate these arguments. By paying attention to these dynamics, international relations scholars can better understand how balancing works in specific cases, how it manifests more broadly in interna­tional politics, and why it sometimes fails in situations where it ought to work well.

Why has transnational war volunteering increased so dramatically in the Muslim world since 1980? Standard explanations, which emphasize U.S.-Saudi support for the 1980s Afghan mujahideen, the growth of Islamism, or the spread of Wahhabism are insufficient. The increase in transnational war volunteering is better explained as the product of a pan-Islamic identity movement that grew strong in the 1970s Arab world from elite competition among exiled Islamists in international Islamic organizations and Muslim regimes.

"The United States' determination on minimizing Iran's regional role has led in actuality to the adoption and pursuit of an oppositional posture and role on the part of Iran. This dichotomous situation and role-playing has important implications for foreign policymakers in Tehran and Washington. If the United States continues to ignore Iran's increased role in the region, Washington risks disrupting the natural power equations, potentially exacerbating the conflict. If, however, the United States can accept Iran's role in the region's new security architecture, especially in the Persian Gulf area, and change its policy of castigating Iran as the main source of threat for the region, Washington and Tehran can ultimately reach a practical rapprochement and find an accommodation that will advance the interests of both states in the region."

"...[W]hile the traditional form of balance of power between Iran and Iraq provided security for the Arab states of the Persian Gulf, it favored the interests of foreign actors, especially the United States. Proponents of such a view hold that following the overthrow of the Baathist regime in Iraq and the growth of Iran's role and influence in the region, the international community ought to establish a new kind of balance of power to restrain the Islamic Republic of Iran, and thereby preserve the security of the region. Following its failure to redefine the position of the new Iraq in terms of a new balance of power, the United States has itself tried to play such a role in the region. U.S. efforts to minimize Iran's role within the context of the new balance of power have consequently created another security dilemma in the Persian Gulf."

"The prevailing view in the United States is that Ahmadinejad's foreign policy and Iran's increasing presence in the region has been offensive, expansionist, opportunistic, and often ideological. Though Iran has occasionally taken advantage of new opportunities, these characterizations have been exaggerated in the United States. Instead, Iran's action should be perceived in a more pragmatic light. Though Ahmadinejad may himself be an ideological and divisive figure, Iran's foreign policy strategy predates him and ought to be viewed as a wider Iranian effort to secure its geostrategic interests and national security concerns. Despite Ahmadinejad's tendencies to indulge his eccentricities, the logic of Iran's foreign policy decisionmaking process always ensures this return to pragmatism."
