This report discusses one alternative to the cur- rent U.S. approach, a realist grand strategy of restraint, which has long been prominent in the academic security studies community. To help leaders and the public evaluate this option, which has now entered the policy discourse, this report describes how U.S. regional security poli- cies would change if the United States adopted this grand strategy. For analysts, we also offer a framework for identifying the set of security policy issues that any grand strategy needs to inform for each region, focusing on conditions under which the United States would use force, U.S. relationships with potential adversaries and allies, military pos- ture, and security cooperation activities. The report also identifies unanswered questions about a grand strategy of restraint and proposes next steps for clarifying the policy implications of such a strategy in each region. The research in this report was completed in November 2020 and was conducted within the RAND Center for Analysis of U.S. Grand Strategy. The center’s mission is to inform the debate about the U.S. role in the world by more clearly specifying new approaches to U.S. grand strategy, evaluating the logic of different approaches, and identifying the trade-offs each option creates. Initial funding for the center was provided by a seed grant from the Charles Koch Institute. On going funding comes from RAND supporters, and from founda- tions and philanthropists. The center is an initiative of the International Security and Defense Policy Center of the RAND National Security Research Divi- iii iv Implementing Restraint sion (NSRD). NSRD conducts research and analysis for the Office of the Secretary of Defense, the U.S. Intelligence Community, U.S. State Department, allied foreign governments, and foundations.
