and the 2017 National Security Strategy and 2018 National Defense Strategy cemented the
shi, identifying China and Russia as the main priorities for the US Department of Defense.
25
e 2021
Interim National Security Strategic Guidance—as noted in this report’s introduction—retained this focus on
great power competition, although the US has embraced ‘strategic competition’ as a framing device.
26
Further illustrating the shi toward great power competition, US Secretary of Defense Lloyd Austin at his
conrmation hearing called China “the most signicant threat going forward” and noted that the US has
“seen [China] do a number of things that tend to make us believe that China wants to be the preeminent
power in the world in the not too-distant future.”
27
Austin asserted that China “is clearly a competitor that we
have to make sure that we begin to check their aggression.”
28
Moreover, in September 2021, US Department
of Defense Policy Chief Colin Kahl acknowledged the short-term threat that Russia poses to the US, stating,
“In the coming years, Russia may actually represent the primary security challenge that we face in the military
domain for the United States and certainly for Europe,” continuing, “Russia is an increasingly assertive
adversary that remains determined to enhance its global inuence and play a disruptive role on the global
stage, including through attempts to divide the West.”
29
US service-specic posture statements and command guidance documents reect this focus on great power
competition and conict.

For example, the 2021 budget submission for the US Department of the Air Force
seeks to align the Air Forces’ portfolios and develop operational concepts in accordance with the National
Defense Strategy, such as investing in logistics that can support rapid deployment of forces to forward
locations and the generation of combat power.
31
e US also seeks to limit the inuence of China and Russia
by repositioning its forces and upgrading military capabilities, especially in the Indo-Pacic region (to counter
China) and the North Atlantic (through the reestablishment of the US Navy’s Second Fleet, responsible for
the US east coast and the North Atlantic Ocean).
