Since the end of the Cold War — if not decades prior — USFK has not been structured, resourced, trained or otherwise intended for direct combat against the PLA, in a Taiwan scenario or otherwise.
Likewise, the US did not expect the ROK to jump in should things get kinetic across the Taiwan Strait.
However, Washington has since made a 180, after Pentagon defense planners and strategists
arrived at the realization that the US will have to throw its "allies" — willing or otherwise — at the PLA to have any chance in a confrontation over Taiwan.
Most notably, USFK CG Xavier Brunson recently started releasing writeups and delivering speeches [

] pushing the South Korean authorities and military to contribute to "stability across the region," and "deterrence" against Russia and China.
In a paper titled
dated November 16, 2025, General Brunson stated:
Korea is positioned to address northern threats from Russia while simultaneously providing western reach against Chinese activities in the waters between Korea and China.
More specifically, this perspective highlights the peninsula's capacity to impose cost on Russia not allowing their fleet to come into the waters east of Korea, effectively making that a more defensible maritime area and limiting adversary naval movements.
Similarly, in the waters off the west coast of Korea, the East-Up orientation clarifies how forces on the peninsula can impose costs, not only on the CCP’s Northern Theater Army, but also on the Northern Fleet, thus demonstrating the significant strategic potential that exists on the peninsula to influence adversary operations in both adjacent seas.
However, despite American pressure, the South Koreans are — unsurprisingly — not particularly keen on being dragged into a potential hot war against a nuclear armed neighbor that also happens to be its #1 trading partner.
This reluctance was fully visible on February 18th, when the PLAAF intercepted ~10 USAF F-16 fighters — flying out of Osan Air Base — over the Yellow Sea. Per
, a South Korean newspaper of record:
The U.S. side notified South Korea of the training in advance but did not explain specific plans or objectives, according to sources. Military authorities are understood to have conveyed concerns to the U.S. after becoming aware of the training.
This training was a US-only exercise without the participation of the South Korean Air Force, and USFK reportedly did not inform South Korean forces of the training plans or objectives.
If South Korea were more willing to confront China — as Uncle Sam now desires — the ROKAF would likely have participated in the USAF exercise.
Assuming Chosun Daily's report is indeed accurate: USFK's failure to advise the ROK MND of the exercise's "specific plans" implies the US operated under the assumption that the ROK would not have approved of them, and that Seoul does not wish to find itself in the middle of awkward tensions — let alone a brawl — between Beijing and Washington.
To put it bluntly, Seoul won't allow itself to be militarily injected into a Taiwan scenario unless Washington quite literally extorts its cooperation.
