Improvements in Russian and Chinese counterspace capabilities could endanger the space-based capabilities that the United States relies on for a broad array of military and economic functions. The proliferation of U.S. and adversary capabilities could lead to unstable competition in space, raising the risk of unintended military escalation. In this report, the authors examine the conventional wisdom on escalation in the space domain to offer recommendations for how the U.S. Space Force (USSF) and other stakeholders can better prepare to deter and manage escalation. They investigate the implications of six propositions related to stability: (1) the incentives to employ offensive capabilities early in a conflict, (2) the benefits of leveraging foreign and commercial systems, (3) the utility of communications channels for crisis prevention and de-escalation, (4) the feasibility of promoting shared norms of responsible behavior, (5) the strategic benefits of selective revelation, and (6) the use of reversible capabilities to manage escalation.

A war between the United States and a capable, nuclear-armed adversary would introduce the risk of destruction on a scale the United States has not seriously contemplated since the end of the Cold War. The main debate in the policy world is between advocates of theories of victory that are reliant on denial and advocates of theories of victory that depend on cost imposition. Cost-imposition strategies, such as those requiring a distant blockade or a punitive air campaign, require the United States to successfully navigate what the authors refer to as the Goldilocks Challenge: specifically, identifying with high confidence a “sweet spot” of pressure points that are valuable enough to influence enemy decisionmaking but not so valuable that they cause unacceptable retaliation. To help the U.S. Air Force evaluate the feasibility of a cost-imposition strategy and assess the associated risks of uncontrolled escalation, the authors examine the ability of past decisionmakers to identify adversary thresholds and to apply this information to control escalation during militarized crises between nuclear-armed states. The authors analyze three historical cases of militarized crises and conflicts between nuclear-armed major powers: (1) the 1962 Cuban Missile Crisis between the United States and the Soviet Union, (2) the 1969 border conflict between China and the Soviet Union, and (3) the 1995–1996 crisis between the United States and China over Taiwan.

Over the past decade, China has upended the world of development assistance, rapidly becoming the world's largest bilateral lender by channeling large sums of money into the developing world. As China's economic engagement in the developing world has grown, so too have U.S. and allied concerns that China is leveraging development assistance to assert Chinese influence, weaken the United States' relative position, and achieve Beijing's broader national security interests. In this report, the authors conduct a net assessment of U.S. and Chinese development assistance and cooperation. The authors describe each country's differing approaches to economic engagement with developing countries and conduct a data-driven comparison to identify strategic asymmetries that might present opportunities for the United States to better compete with China for relationships and influence in the developing world. The assessment reveals that Chinese economic engagement in the developing world should not be conceptualized as aid or assistance; this mischaracterization has potentially led to an overreliance on U.S. development tools as a primary response. Moreover, despite evidence of the short-term benefits that China might gain from its development financing, it is not clear whether these benefits are sustainable or effective over the long term when compared with the U.S. approach. Nevertheless, China's efforts — its heavy emphasis on energy and infrastructure projects, its approach to working through elite actors in developing countries, and its willing embrace of greater risk and reduced transparency — create challenges and opportunities for the United States as it looks to compete with China in the developing world.
