This article explores the new agenda of resilience shift in the US defense strategy, analyzes its potential impact on national security, points out the shortcomings of domestic and foreign research in this field, and attempts to systematically discuss the connotation, reasons, internal logic, and its manifestation and possible impact on the military situation of defense resilience.

1、 The Connotation of US Defense Resilience

Deeply explored the connotation of US defense resilience and its position in national security strategy. Resilience, as an interdisciplinary concept, has been highly valued in political science and international relations research since 2010, particularly in the areas of security governance, crisis management, and defense construction. The focus on resilience in the US National Security Strategy began in 2010, when the Obama administration proposed strengthening domestic security and resilience. However, it was not until the National Security Strategy report released by the Biden administration in 2022 that resilience was explicitly identified as one of the top priorities of the US defense strategy.

2、 Building US Defense Resilience Driven by Triple Challenges

An in-depth analysis was conducted on the urgency of building the resilience of the US national defense, pointing out the reasons why it has become a national defense strategic priority. US decision-makers believe that defense construction is facing three challenges: great power competition, transnational threats, and capability decline. In the competition among major powers, China and Russia are seen as the main rivals, and their military behavior and capability growth pose a challenge to the United States, especially in advanced weapon systems such as hypersonic missiles. Transnational threats such as climate change and epidemics have an impact on national defense infrastructure and military activities. The COVID-19 epidemic has exposed the vulnerability of the defense supply chain. The decline of national defense capabilities is reflected in the decline of innovation and manufacturing capabilities in the defense industry, as well as the weakening of military combat capabilities, especially in terms of naval power. These factors have prompted the United States to strengthen its defense resilience building to address challenges and maintain military superiority.

3、 The Inner Logic of US Defense Resilience Construction

An in-depth analysis was conducted on the internal logic of US defense resilience construction, which was summarized from three dimensions: target orientation, areas of concern, and construction subjects. The construction of US national defense resilience aims to strengthen the defense's resistance, deterrence, and enforcement capabilities to cope with the challenges of great power competition, transnational threats, and capability decline. Specifically, the United States enhances its defense and deterrence capabilities by improving the deterrence capabilities of its allies and partner countries, retrofitting military facilities to withstand extreme weather, building a more resilient nuclear deterrence system, and strengthening the defense of critical infrastructure. At the same time, the United States also supports its coercive diplomacy by strengthening its defense capabilities.

4、 The US military posture under the construction of national defense resilience

In depth exploration of the changes in the military posture of the United States under the construction of national defense resilience, especially in the Indo Pacific region. The transformation is mainly reflected in the updating of combat concepts, the adjustment of troop structure and deployment, and the strengthening of national defense capacity building.

5、 The Impact of US Defense Resilience Construction

In depth analysis of the multifaceted impact of US defense resilience construction on international and regional security situations. Firstly, the United States sees China as a potential opponent in the development of its defense capabilities, and its defense resilience construction may promote a re adjustment of the military balance between China and the United States in the Western Pacific region, affect China's defense of national interests in Taiwan and the South China Sea issues, and potentially induce the United States to take risky military actions against China. Secondly, the construction of US defense resilience provides a new path and link for cooperation between the United States and its alliance system, which helps to stabilize and strengthen the alliance system, such as strengthening cooperation with NATO allies in the field of security resilience construction, and cooperating with military bases of allies such as Australia in the Asia Pacific region. Finally, the strengthening of defense resilience in the United States poses a challenge to strategic stability, especially in the space and nuclear fields. It may change the strategic stability pattern based on mutual assurance of vulnerability, increase the complexity of the space security situation, and by enhancing the resilience of nuclear command, control, and communication systems, it may undermine strategic stability, enhance the responsiveness of US nuclear forces, and affect the nuclear deterrence capabilities of other countries.

conclusion

It emphasized the changes in the US defense strategy after the Cold War, especially the emphasis on building national defense resilience in the context of the relatively weak US defense forces. The United States prioritizes the construction of national defense resilience, aiming to reshape military hegemony by enhancing defense resilience and strengthening deterrence. This strategic shift will have a profound impact on international and regional security. China should calmly and rationally view the United States' defense resilience construction, recognize the challenges it may bring, and also recognize the limiting factors that the United States may face in the implementation process. It is expected that the United States will make breakthroughs in resilience building in areas such as missile defense and military base defense, but progress in the defense industry may be slower.
