Hours earlier than South Korea and america started Ulchi Freedom Defend on August 17, U.S. President Donald Trump ordered the Pentagon to “considerably cut back” the train. He known as the drills “pricey” and an “inappropriate and hostile” sign to North Korea, emphasised his “superb relationship” with North Korean chief Kim Jong Un, and linked his displeasure to Seoul’s refusal to affix U.S. motion towards Iran. He famous in a put up on Reality Social that the workouts have been being scaled again, not scrapped fully, solely as a result of “it’s too late to cancel.”
The train however began as scheduled, whereas the Pentagon provided no public rationalization of what can be lower. This ambiguity makes the quick army penalties troublesome to measure. It additionally reveals a extra critical alliance downside. A recurring mixed train, developed by months of bilateral planning towards a nuclear-armed adversary, was recast in a single day as an instrument of presidential diplomacy and leverage over an ally.
One shortened train – if certainly Ulchi Freedom Defend is scaled again – is not going to undo the South Korea-U.S. mixed protection posture. Repeated uncertainty over whether or not future workouts will proceed, nonetheless, may weaken readiness, disrupt the transition of wartime operational management, and cut back confidence in alliance session. If Washington needs to make use of army restraint to reopen diplomacy with Pyongyang, it should achieve this in live performance with Seoul and in return for significant North Korean restraint.
The Final-Minute Discount
Ulchi Freedom Defend is an 11-day mixed train involving about 18,000 South Korean personnel. It integrates computer-assisted command-post coaching with discipline workouts and this yr incorporates classes from latest wars, together with drone operations, GPS disruption, and cyberattacks. Even earlier than Trump’s order, the allies had deliberate 14 battalion-level or bigger discipline workouts, down from 17 in 2025. The general variety of South Korean individuals remained roughly unchanged.
As a result of the order – if a put up on Reality Social might be known as that – arrived solely hours earlier than the train started, canceling or redesigning the command-post part would create extra disruption than financial savings. The likelier near-term choices are narrower U.S. participation, fewer supporting property, or reductions in discipline occasions that haven’t but occurred. Till detailed steering emerges, it’s troublesome to judge the precise influence.
Nevertheless, the worth of Ulchi Freedom Defend can’t be counted solely in troops or discipline occasions. It rehearses the equipment that may enable two nationwide militaries to function as one power in a disaster: command relationships, intelligence flows, reinforcement, logistics, missile protection, and civil-military coordination. Smaller coaching can mitigate gaps, however it can’t totally reproduce theater-level decision-making beneath strain.
Ulchi Freedom Defend 2026 additionally has an unusually necessary institutional goal. The allies deliberate to make use of it to evaluate agreed capabilities and methods supporting the conditions-based transition of wartime operational management. Seoul hoped {that a} profitable evaluation would allow certification of the long run Mixed Forces Command’s full operational functionality and help dialogue of a transition timeline later this yr. A serious last-minute change may due to this fact have an effect on greater than readiness; it may complicate an alliance venture that Washington itself has lengthy inspired.
This exposes a contradiction in present U.S. coverage. The 2026 U.S. Nationwide Protection Technique requires South Korea to take major duty for deterring North Korea with “vital however extra restricted” U.S. help. That shift requires stronger mixed planning and credible validation of South Korean command capability. Workouts are one of many predominant mechanisms for transferring and testing larger duty. Curbing them, particularly with out prior dialogue, makes burden-sharing more durable to implement, at the same time as Washington calls for extra of it.
Trump’s reference to Iran is much more damaging. He ended his put up with a remark criticizing Seoul’s reluctance to affix the Israeli-U.S. strikes on Iran. Trump himself known as the Iran issue “considerably unrelated (?)” (sic) to the choice to cut back workouts, solely including to the confusion.
The U.S.-ROK Mutual Protection Treaty is centered on “widespread hazard” in “the Pacific space.” Any South Korean contribution to operations involving Iran should additionally account for home authorized procedures, obtainable forces, and quick necessities on the peninsula.
Washington can ask Seoul to contribute to wider safety challenges, and South Korea ought to critically think about requests involving shared pursuits reminiscent of maritime safety and the safety of sea lanes. However conditioning joint workouts – a core mechanism of peninsula protection – on participation in an unrelated army marketing campaign modifications calls into query alliance solidarity.
Seoul is rising protection spending, increasing standard capabilities, and accepting a bigger position in deterring North Korea – all according to Trump’s said preferences. A requirement for allies to take larger duty for their very own protection is sustainable when paired with dependable U.S. help and predictable session. If U.S. participation might be lowered all of a sudden as a result of Seoul declined an out-of-area request, South Korean policymakers will fairly query whether or not alliance choices are nonetheless ruled by widespread technique.
The Threat of Seoul Being Sidelined
Trump has carried out this earlier than. After the 2018 Singapore summit with Kim Jong Un, Trump stunned each South Korean and U.S. army officers by asserting the suspension of main workouts. The pause created house for diplomacy with North Korea, however it additionally produced a measurable degradation in combined-force readiness. Three Trump-Kim conferences in the end had no lasting influence on curbing North Korea’s nuclear weapons or ballistic missile improvement.
Actually army restraint can help diplomacy when it’s coordinated, restricted in time, and exchanged for reciprocal measures. The 2018 expertise, nonetheless, exhibits the hazard of granting a visual concession earlier than North Korea agrees to make any concessions of its personal.
Trump might hope {that a} discount in Ulchi Freedom Defend will assist revive direct dialogue with Kim. South Korean President Lee Jae-myung additionally favors renewed engagement, and the presidential workplace responded cautiously by expressing hope that the “pleasant” Kim-Trump relationship “will result in significant US-North Korea dialogue.” A coordinated discount may due to this fact help each governments’ diplomatic targets.
The present strategic setting, nonetheless, is much less favorable than it was in 2018. North Korea has deepened army cooperation with Russia. North Korean troops have gained battlefield expertise within the Russia-Ukraine conflict, whereas Pyongyang continues to enhance its missiles and has carried out two ballistic missile launches since August 6. Simply earlier than Ulchi Freedom Defend, North Korea threatened to strengthen its nuclear deterrent in response to the train. Trump simply rewarded this conduct, even calling North Korea’s conduct usually “unthreatening and respectful.”
In the meantime, Pyongyang has recast inter-Korean relations by its “two hostile states” coverage and constantly rejects all outreach from Seoul. Below these circumstances, a U.S. concession made with out prior allied settlement can reinforce Pyongyang’s choice for dealing straight with Washington whereas excluding Seoul. That is the dynamic South Koreans typically name “Korea passing.” It isn’t an inevitable results of North Korea-U.S. diplomacy, however the threat grows when Washington demonstrates that it could alter mixed army exercise first and seek the advice of Seoul afterward.
Restoring Joint Management of Alliance Selections
Seoul ought to keep away from each a public confrontation with Trump and passive acceptance of an undefined order. The quick precedence is a joint political and army evaluate that clarifies which actions are affected and protects the important command-post capabilities, the operational management evaluation, and coaching involving vital U.S. enablers. If some discipline occasions or U.S. deployments are lowered, the allies ought to establish compensatory coaching slightly than enable short-term cuts to turn into an unplanned new baseline.
The 2 governments additionally want guidelines for future train changes. Any change supposed to advance diplomacy must be collectively determined, time-limited, reversible, and linked to observable North Korean motion. Train coverage ought to stay separate from commerce disputes and requests for South Korean participation in operations exterior the peninsula. Washington might search wider contributions from Seoul, however these discussions belong in their very own strategic and authorized framework.
For its half, South Korea ought to proceed strengthening unbiased intelligence, command-and-control, missile protection, precision-strike, and sustainment capabilities. Larger self-reliance will make the alliance extra resilient to modifications in U.S. power posture. It can’t substitute for mixed coaching, nonetheless, as a result of deterrence depends upon an adversary believing that U.S. and South Korean forces can combat collectively, not merely that every possesses succesful weapons.
The alliance can take up one late and partially applied order. It is going to wrestle if mixed readiness turns into a bargaining chip that may be exchanged for diplomatic atmospherics or used to punish disagreement on unrelated points. Trump’s determination may nonetheless turn into the opening to a coordinated diplomatic initiative. With out reciprocal North Korean steps and real session with Seoul, nonetheless, it’s extra more likely to expose a widening hole between the alliance’s formal commitments and the best way its most consequential choices are made.
