China’s approach to nuclear deterrence has been broadly consistent since its first test in 1964, but it has recently accelerated nuclear force modernization. China’s strategic environment is likely to grow more complex, and nuclear constituencies are gaining a larger bureaucratic voice. Beijing is unlikely to change official nuclear policies but will probably increase emphasis on nuclear deterrence and may adjust the definition of key concepts.

As the U.S. National Defense Strategy recognizes, the United States is currently locked in a great-power competition with Russia. This report seeks to define areas where the United States can compete to its own advantage. It examines Russian vulnerabilities and anxieties; analyzes potential policy options to exploit them; and assesses the associated benefits, costs, and risks, as well as the likelihood of successful implementation.

As the United States creates the Space Force as a service within the Department of the Air Force, RAND assessed which units to bring into the Space Force, analyzed career field sustainability, and drew lessons from other defense organizations. The report focuses on implications for effectiveness, efficiency, independence, and sense of identity for the new service.

A RAND study analyzed Chinese and U.S. military capabilities in two scenarios (Taiwan and the Spratly Islands) from 1996 to 2017, finding that trends in most, but not all, areas run strongly against the United States. While U.S. aggregate power remains greater than China’s, distance and geography affect outcomes. China is capable of challenging U.S. military dominance on its immediate periphery—and its reach is likely to grow in the years ahead.
