A United States commander said treaty allies South Korea, Japan and the Philippines could form a “strategic triangle” to contain China if military planners view the region from a nontraditional perspective, with east orientation at the top.
General Xavier T. Brunson, commander of U.S. forces in South Korea, wrote in a Sunday article that the east-up map, rather than the standard north-up one, shows the collective potential of connecting the three allied nations as a triangle, creating what he called “an integrated network” for situational awareness and coordinated responses.
Newsweek reached out to the Chinese Foreign Ministry for comment.
Why It Matters
The U.S. has long leveraged the territories of allied and partner nations in the western Pacific to deter potential Chinese aggression. Under its island chain strategy, Japan, Taiwan and the Philippines form a north-south defensive line east of China, intended to help U.S. forces project power in the region amid China’s growing military presence.
Brunson’s concept of the east-up map comes as the U.S. and South Korea modernize their 72-year alliance to address security challenges outside the Korean Peninsula. U.S. Defense Secretary Pete Hegseth recently suggested that the U.S. Forces Korea could be deployed for “regional contingencies” in addition to deterring North Korea’s threats.
What To Know
In an article published on the U.S. Forces Korea website, Brunson said the Indo-Pacific is a region where geographic relations determine “operational possibilities and alliance effectiveness,” noting that hidden strategic advantages could be revealed by simply rotating the standard north-up map to show Japan and the Philippines above China.
“When the same region is viewed with east orientation toward the top, the strategic picture transforms dramatically,” the general wrote, adding that this new perspective revealed his forces are no longer “distant assets” but are “positioned inside the bubble perimeter that the U.S. would need to penetrate in the event of crisis or contingency.”
The U.S. military deploys about 28,500 troops in South Korea, along with fighter jets and unmanned aircraft. Its primary mission is to deter aggression and defend South Korea to maintain regional stability, a role the U.S. has held since the Korean War.
“This shift in perspective illuminates [South] Korea’s role as a natural strategic pivot,” the commander said, noting that the ally is positioned to address threats from Russia while providing reach against Chinese activity in the waters between the two nations, demonstrating its significant strategic potential to influence adversary operations.
The U.S. general was referring to China’s military presence in the disputed waters of the Yellow Sea, where Beijing and Seoul have yet to establish a maritime boundary.
Regarding the strategic triangle framework, Brunson said South Korea has what he called the “added advantage of cost-imposition capabilities” against both Russian and Chinese forces, due to its strategic depth and central position on the east-up map.
While Japan has advanced technologies and controls key maritime chokepoints along Pacific shipping lanes, the Philippines provides southern access points and oversight of vital sea lanes connecting the Pacific and Indian Oceans, the general explained.
The commander urged military planners to experiment with east-up mapping when analyzing opportunities for alliance coordination and existing force positioning advantages in the Indo-Pacific, which traditional north-up mapping still obscures.
What People Are Saying
General Xavier T. Brunson, commander of the U.S. Forces Korea, wrote in an article on Sunday: “The geographic advantages we seek may already exist, waiting to be recognized through a simple shift in perspective. The question for military planners is not whether geography matters, it is whether we are seeing it clearly enough to recognize the strategic opportunities it provides, and whether we have the courage to view familiar perspectives through fresh eyes.”
U.S. Defense Secretary Pete Hegseth said on November 4: “There’s no doubt flexibility for regional contingencies is something we would take a look at, but we are focused on standing by our allies [in South Korea] and ensuring the threat of the [Democratic People’s Republic of Korea, North Korea] is not a threat to the Republic of Korea and certainly continue to extend nuclear deterrence as we have before.”
What Happens Next
It remains unclear how the U.S. Forces Korea will adjust its posture to respond to regional contingencies while continuing its mission to deter North Korea’s aggression.
