Renewed Great Power Competition: Implications for Defense--Issues for Congress [Updated March 4, 2021] [open pdf - 1MB]
From the Summary: "The renewal of great power competition was acknowledged alongside other considerations in the Obama Administration's June 2015 National Military Strategy, and was placed at the center of the Trump Administration's December 2017 National Security Strategy (NSS) and January 2018 National Defense Strategy (NDS). The December 2017 NSS and January 2018 NDS formally reoriented U.S. national security strategy and U.S. defense strategy toward an explicit primary focus on great power competition with China and Russia. Department of Defense (DOD) officials subsequently identified countering China's military capabilities as DOD's top priority. [...] The issue for Congress is how U.S. defense planning should respond to renewed great power competition, and whether to approve, reject, or modify the Biden Administration's proposed defense funding levels, strategy, plans, and programs for addressing renewed great power competition. Congress's decisions on these issues could have significant implications for U.S. defense capabilities and funding requirements."
