Reuters Homeland security is the top priority in the Pentagon's new National Defense Strategy.
In a significant shift to its security priorities, the US Department of Defense now considers security of the US homeland and Western Hemisphere - not China - as its primary concern.
Previous versions of the strategy - published every four years - named the threat posed by China as the top defence priority.
Relations with China will now be approached through "strength, not confrontation", the report says.
By comparison, in 2018, the Pentagon described "revisionist powers", such as China and Russia, as the "central challenge" to US security.
Unlike in previous versions of the strategy, Taiwan, the self-governing island claimed by China, is not mentioned.
However, the document does write that the US aims to "prevent anyone, including China, from being able to dominate us or our allies". »
