China's defense industrial base is operating on a wartime footing, while the U. S. defense industrial base is largely operating on a peacetime footing. Overall, the U. S. defense industrial ecosystem lacks the capacity, responsiveness, flexibility, and surge capability to meet the U. S. military's production and warfighting needs. Unless there are urgent changes, the United States risks weakening deterrence and undermining its wartime capabilities. China is heavily investing in munitions and acquiring high-end weapons systems and equipment five to six times faster than the United States. China is also the world's largest shipbuilder and has a shipbuilding capacity that is roughly 230 times larger than the United States. One of China's large shipyards, such as Jiangnan Shipyard, has more capacity than all U. S. shipyards combined.

This CSIS report states that terrorism is no longer the leading international threat to the United States or its top defense priority, but challenges related to violent extremism remain. The threat from Salafi-jihadist groups such as al Qaeda and the Islamic State has declined, and ethnonationalist threats are largely contained. However, a broader patchwork of violent far-left extremist ideologies has become more prominent on the global stage.
