Categorising the prospect of any competitor controlling the South China Sea as another major security challenge—one in which a potentially hostile power could impose a “toll” on one of the world’s most critical commercial arteries or open and close it at will—the document calls for developing “strong measures” and the deterrence required to keep those sea lanes open. “This will require not just further investment in our military—especially naval—capabilities, but also strong cooperation with every nation that stands to suffer, from India to Japan and beyond, if this problem is not addressed,” it adds.
Despite its emphasis on the Indo-Pacific and the broader Asian region, the document identifies the Western Hemisphere as the area where the US will likely concentrate most of its efforts, describing it as the country’s own hemisphere. “After years of neglect, the United States will reassert and enforce the Monroe Doctrine to restore American preeminence in the Western Hemisphere, and to protect our homeland and our access to key geographies throughout the region,” it states, adding that Washington will seek to deny non-Hemispheric competitors the ability to position forces or other threatening capabilities, or to own or control strategically vital assets, in the region. The document refers to this as the “Trump Corollary” to the Monroe Doctrine and frames the restoration of American power and priorities in the hemisphere as the objective.
