On this week's episode of Security Dilemma, John Allen Gay and A.J. Manuzzi interviewed Sabreena Croteau. Sabreena is a Research Fellow at Defense Priorities and recently defended her dissertation to earn her doctorate in Political Science from the University of Chicago. Her dissertation, titled “Security the Seas: The Political Economy of Naval Force Structure,” uses an economic approach to examine the variance in the development of naval power across states, and intends to draw policy-relevant implications for U.S. grand strategy, the pivot to Asia, and competition with China as a rising economic power. Our conversation discussed how economic considerations influence how great powers construct their navies, how U.S. policymakers should think about sea lanes, and China and Russia's Arctic ambitions.
