Retired colonel knocks Trump order to cut back on ‘critical’ joint exercises with South Korea

Trump’s Exercise Cuts Draw Sharp Pushback From a Retired Air Force Officer

Provpnadvice.com – The decision by President Trump to sharply trim the scale of annual joint military drills with South Korea has ignited a debate over whether Washington is undermining a decades-old alliance architecture that underpins security across the entire Pacific. Speaking on CNN’s “Newsroom” program on Sunday, retired Air Force Colonel Cedric Leighton — who left active duty in 2010 — labeled the move “an unforced error” and warned it carries ripple effects that extend well beyond the Korean Peninsula.

What Trump Ordered and Why

On Sunday, the president announced that he had directed Defense Secretary Pete Hegseth to “substantially reduce” the combined training exercises scheduled to run from Monday through August 27. In a post on Truth Social, Trump framed the decision in two distinct terms: fiscal burden and diplomatic signaling.

“These exercises are not only costly, with much of these costs paid for by the United States of America (as usual!), but send a signal that is totally inappropriate and hostile, to a Country that, as long as Donald J. Trump has been President, has been unthreatening and respectful.”

The “country” in question is North Korea. Trump has long cultivated a personal rapport with Pyongyang’s leader, Kim Jong Un. During his first term, the two leaders met face-to-face on three occasions — a series of summits that drew global attention and reshaped expectations about inter-Korean diplomacy. In his second term, however, no in-person meeting has taken place, yet Trump maintained on Sunday that he retains a “very good relationship” with Kim. He also voiced displeasure that the United States and South Korea had agreed, decades earlier, to conduct the joint drills in the first place.

The Financial Picture Leighton Challenges

Trump’s assertion that Washington bears the bulk of exercise costs sits in tension with the way the alliance’s cost-sharing arrangement actually functions. Leighton pushed back directly on that premise during his interview with host Brian Abel.

“South Korea is a critical ally for us. And, oh, by the way, they pay for a large portion of those exercises. They also pay for the upkeep of U.S. troops in South Korea. So the idea that we’re paying for everything there is absolutely false.”

Under the Special Measures Agreement governing the U.S. Forces Korea garrison, Seoul has historically shouldered a substantial share of infrastructure, construction, and logistical costs associated with the roughly 28,500 American service members stationed on the peninsula. The joint exercises themselves — which typically involve tens of thousands of troops from both nations, naval units, and air assets — carry their own cost structure, and Seoul’s contribution has grown in recent budget cycles. Leighton’s point is that the president’s framing obscures a financial reality that has been in place for years.

Strategic Stakes Beyond the Peninsula

Leighton argued that the drills are not merely a bilateral ritual between Washington and Seoul. They serve as a rehearsal for collective defense scenarios that would protect Japan as well as the continental United States. In his view, shrinking the exercises hands Pyongyang a tactical and informational edge at precisely the moment when deterrence credibility matters most.

“The things that we do in those exercises are critical for the joint defense, not only of South Korea and Japan, but also for defense of the United States as well. And … in this particular situation, what you’re seeing is the North Koreans are getting an advantage, really an unforced error on our part.”

He added that the reduction would erode trust in the alliance.

“And it’s going to damage the relationship that we have with the South Koreans. And that’s not a good thing.”

The Trump–Kim Dynamic: Substance or Spectacle?

Leighton offered a pointed assessment of the personal chemistry between the two leaders. He described the Trump–Kim bond as “ephemeral at best” and expressed concern that the president was placing too much “stock” in a connection whose durability remains untested by actual crisis.

The caution is not without historical grounding. The three first-term summits — in Singapore (2018), on the DMZ (2018), and in Hanoi (2019) — produced no lasting denuclearization framework. North Korea resumed missile testing and nuclear development within months of the Hanoi talks. Since then, Pyongyang has continued to expand its ballistic-missile arsenal and has conducted regular artillery drills near the demilitarized zone, behavior that complicates any narrative of sustained calm.

What the Reduction Means in Practice

Joint exercises between the two militaries have been conducted annually since the Korean War era and have evolved into large-scale, multi-domain operations involving land, sea, and air components. They serve several simultaneous purposes: maintaining interoperability between allied forces, rehearsing combined-response scenarios against a conventional or nuclear threat from the north, and projecting a visible commitment to deterrence that reassures both Seoul and Tokyo. Scaling them back, even temporarily, removes a predictable element of the regional security calendar and forces allied planners to recalibrate assumptions about American readiness.

For Tokyo, which has watched U.S. posture shifts with particular attention given its own North Korean missile threat, any signal that Washington is deprioritizing Pacific alliance commitments invites questions about the reliability of extended deterrence. Leighton’s reference to Japan in his remarks underscores that the exercise question is never purely bilateral.

A Test of Alliance Management

The episode highlights a recurring tension in U.S. alliance policy: the gap between a president’s personal diplomatic instincts and the institutional machinery of collective defense that has been built over generations. Whether the reduced exercises become a one-time adjustment or the opening move in a broader recalibration of the U.S. posture in East Asia will depend on how both Seoul and Tokyo respond in the weeks ahead. What is clear, in Leighton’s framing, is that the decision was made without the full weight of strategic consequence being factored in — an “unforced error,” in his words, that now requires correction before it hardens into precedent.
