Within the realist school of international relations, a prevailing view holds that the anarchic structure of the international system invariably forces the great powers to seek security at one another's expense, dooming even peaceful nations to an unrelenting struggle for power and dominance. Rational Theory of International Politics offers a more nuanced alternative to this view, one that provides answers to the most fundamental and pressing questions of international relations. Why do states sometimes compete and wage war while at other times they cooperate and pursue peace? Does competition.

With sweeping changes in the Soviet Union and East Europe having shaken core assumptions of U.S. defense policy, it is time to reassess basic questions of American nuclear strategy and force requirements. In a comprehensive analysis of these issues, Charles Glaser argues that even before the recent easing of tension with the Soviet Union, the United States should have revised its nuclear strategy, rejecting deterrent threats that require the ability to destroy Soviet nuclear forces and forgoing entirely efforts to limit damage if all-out nuclear war occurs. Changes in the Soviet Union, sugg.

Well before President Donald Trump began rhetorically attacking U.S. allies and the open international trading system, policy analysts worried about challenges to the liberal international order (LIO). A more fundamental issue, however, has received little attention: the analytic value of framing U.S. security in terms of the LIO. Systematic examination shows that this framing creates far more confusion than insight. Even worse, the LIO framing could lead the United States to adopt overly competitive policies and unnecessarily resist change in the face of China's growing power. The "LIO concept"—the logics that proponents identify as underpinning the LIO—is focused inward, leaving it ill equipped to address interactions between members of the LIO and states that lie outside the LIO. In addition, the LIO concept suffers theoretical flaws that further undermine its explanatory value. The behavior that the LIO concept claims to explain—including cooperation under anarchy, effective Western balancing against the Soviet Union, the Cold War peace, and the lack of balancing against the United States following the Cold War—is better explained by other theories, most importantly, defensive realism. Analysis of U.S. international policy would be improved by dropping the LIO terminology entirely and reframing analysis in terms of grand strategy.

Despite the intense focus on China's rise, the United States has yet to confront the most challenging question posed by this power shift: Should it pursue a strategy of limited geopolitical accommodation to avoid conflict? U.S. policy continues to focus almost entirely on preserving the geopolitical status quo in Northeast Asia. Given the shifting power balance in Asia, however, there are strong theoretical rationales for considering whether significant changes to the status quo could increase U.S. security. A possibility designed to provide the benefits of accommodation while reducing its risks is a grand bargain in which the United States ends its commitment to defend Taiwan and, in turn, China peacefully resolves its maritime disputes in the South China and East China Seas and officially accepts the United States' long-term military security role in East Asia. In broad terms, the United States has three other options—unilateral accommodation, a concert of Asian powers, and the current U.S. rebalance to Asia. Unilateral accommodation and the rebalance have advantages that make the choice a close call, but all things considered, a grand bargain is currently the United States' best bet.

How do states' oil requirements influence U.S. national security? Although a great deal of attention has focused on "energy security," scholars and policymakers lack satisfactory answers because little analysis links states' energy requirements with the probability of military conflict. Developing an analytic catalogue of the ways in which states' oil requirements could influence U.S. national security is the first step in closing this gap. Possible mechanisms include vulnerable access to oil that threatens a state's military capability; military policies designed to protect access to oil that threaten another state's military capability, which in turn create an access-driven security dilemma; and oil reserves that increase the value of territory, generating a conflict that draws in the United States via an alliance commitment. A distinctive feature of this framework is that some of these mechanisms identify threats to U.S. security that flow from another country's consumption of oil, not from U.S. consumption. Of particular importance is the potential danger that Chinese oil imports create for U.S. security—China's efforts to protect its sea lines of communication are fueling military competition that could strain U.S.-China relations and increase the probability of conflict between them. Policy options for dealing with these dangers share little with the standard options prescribed for dealing with the dangers related to Persian Gulf oil and U.S. oil consumption.
