For nearly eight decades, United States (US) policy in Asia, especially with its treaty allies, rested primarily on a straightforward bargain: the US provided security while allies accepted a degree of strategic alignment with US objectives in the Pacific. Recently, US President Donald Trump announced on his Truth Social account that joint Ulchi Freedom Shield (UFS) exercises will be ‘reduced.’ Consequently, the exercise, which was to end on August 27, ended prematurely on 21 August 2021. There are two very important things that President Trump mentioned in his tweet: the North Korean factor and the cost of this exercise. Trump administration’s approach towards its Asian allies has a very fundamental contradiction. The United States (US) is seeking primacy in Asia Pacific, but it is has increasingly started rejecting the economic, political, and security costs of it. The controversy surrounding the recent UFS exercises is a very interesting entry point into this much larger problem. Therefore, this op-ed will argue that transactionalism that is currently underpinning US policies towards its allies is not a leaner version of its strategy in Asia rather an undermining one.

The UFS episode is not the first time Trump was seen as criticizing allies while challenging the value of long-standing partnerships. But what stands out about this episode is the reason Trump cited to cut these exercises short. His statement cited Trump's "very good relationship" with the North Korean leader and described the exercises as costly and hostile. Seoul, by contrast, was caught off guard as its own officials had no prior knowledge of the decision, underscoring how one-sided it was. During a parliamentary session, Foreign Minister Cho Hyun said that there were no prior discussions amongst Korean or US military officials about this decision. Another issue that Trump highlighted in his statement was Seoul’s reluctance to participate in the US naval blockade in the Strait of Hormuz. Soon after the UFS episode, it was reported that Seoul is considering joining the US naval blockade, as it has been severely affected by the closure of the Strait. These developments are unsettling as they unveil a deeper problem in the alliance system where the US is continuously treating allies are recipient of decisions rather than parties to them.

The first rationale for scaling down the exercise was diplomatic: a smaller drill, Trump argued, would create space for dialogue with Kim Jong Un ahead of their planned bilateral summit later this year. Pyongyang's state media dismissed the reduction as changing nothing, and Kim Yo Jong stated that the drills' "provocative, aggressive nature" would not change merely because their duration and scale had shrunk. North Korea had also test-fired short-range ballistic missiles earlier in the month, and reporting has noted that a missile launch on the same day Trump announced the cut was read by some officials as a signal directed at the drills Washington was already moving to curtail rather than a response prompted by them. This clearly demonstrated that this concession by Trump didn’t buy promised de-escalation from the North Korean side.

The second was the “cost rationale,” as Trump described UFS as costly. The reality however, is different as the cost of scaling down exercises was never primarily denominated in dollars. The actual cost was the operational readiness, and the years of institutional trust required to sustain alliances. UFS 2026 was meant to help assess the conditions for transferring wartime operational control (OPCON) from Washington to Seoul, a project the United States itself has spent years encouraging as part of burden-sharing. A last-minute, unconsulted cut to the very exercise meant to validate that transition undercuts the policy Washington claims to want. Seoul's response was telling: rather than simply absorb the blow, Lee's government used an emergency Cabinet session to accelerate both the OPCON transition and its nuclear-powered submarine programme, explicitly framing self-reliance as a hedge that strengthens, rather than replaces, the alliance. That is the credibility cost showing up in real time: an ally quietly building independent capacity because it can no longer assume the exercise calendar, or the consultation that is supposed to accompany it, will hold. Once a partner starts planning around the assumption that Washington's commitments are negotiable on short notice, credibility does not return simply because the dollar line item shrinks or grows the following year again.

Every gap opened in the alliance is a gap Beijing does not have to create itself. China has long treated the US-South Korea exercise cycle as a source of regional friction, and its diplomacy has moved accordingly: Foreign Minister Wang Yi was in Seoul for regional security talks in the same week the drills were cut, a coincidence of timing that nonetheless underscored how directly Beijing's interests intersect with Washington's alliance management choices. Beijing does not need Washington to abandon its allies. It only needs Washington to make those allies unsure of what they can count on. Every unconsulted reduction, every contradictory statement between allies, and every acceleration of independent hedging capacity is legible in Beijing as evidence that America's Pacific commitments are conditional, individual-driven, and open to renegotiation on Washington's schedule alone.

None of this means burden-sharing critiques are without merit. Transactionalism has a legitimate corrective role against real imbalances in how alliance costs are shared, and Washington is not wrong to ask whether seven decades of one set of arrangements still fit today's distribution of capability and risk. But renegotiating the terms of an alliance is not the same as treating the alliance itself as a discretionary expense, and unconsulted, last-minute decisions carry a cost of their own for a partner whose territory and forces are directly involved. Until Washington draws that distinction more clearly, allies will keep testing the limits of the arrangement in real time, and Beijing stands to benefit most when they do.
