Lee Jae-myung Praises Trump's Order to End Korea-U.S. Drills Early, Sparks Political Firestorm

On Friday, August 21, 2026, South Korea and the United States wrapped up the Ulchi Freedom Shield (UFS) joint exercise six days ahead of schedule, after President Donald Trump ordered a major scale-back. President Lee Jae-myung’s late-night praise of that decision on social media became the focal point of a national-security firestorm — opposition leaders slammed his remarks as self-delusion, while the ruling Democratic Party rallied to his defense.

What changed in the drills

The UFS is one of two major annual theater-level exercises the allies use to train for contingencies on the Korean Peninsula. This year’s schedule originally ran 11 days, from August 17 through August 27, with about 18,000 South Korean personnel participating alongside U.S. forces.

After Trump’s directive, the allies agreed to cut the exercise to five days, ending on August 21 instead of August 27.

Element	Original plan	After scale-back
Duration	11 days (Aug. 17–27)	5 days (Aug. 17–21)
Field maneuvers	14 battalion-level or larger drills planned	Significantly reduced; some canceled or simulated
Second-week focus	Counterattack-oriented training	Canceled
Overall emphasis	Mixed defensive and counteroffensive scenarios	Mainly defensive operations

South Korea’s Joint Chiefs of Staff said the adjustment came at Washington’s suggestion. A U.S. Department of Defense official told Reuters that the department had substantially reduced associated live-training events, with some canceled or switched to simulations while preserving essential readiness goals.

Why Trump ordered the cut

Trump announced on Sunday, August 16, that he had instructed the Pentagon to “substantially reduce” joint exercises with South Korea. In posts on Truth Social, he said the drills sent a “totally inappropriate and hostile” signal to North Korea, cited their cost, and referenced his “very good relationship” with North Korean leader Kim Jong-un.

He also linked the decision to Seoul’s stance on the U.S.-led campaign against Iran, writing that he had asked whether South Korea would join efforts toward the “denuclearization of the Islamic Republic of Iran” and that Seoul replied “No thanks!”

Speaking at the White House on Wednesday, August 20 (U.S. time), Trump again extended an olive branch to Kim, saying he expects to meet him later in 2026.

Foreign Minister Cho Hyun told lawmakers that neither South Korean nor U.S. officials had been aware in advance of Trump’s order — underscoring how abruptly the decision landed in Seoul.

Lee’s X post and the opposition backlash

Hours after the allies announced the shortened schedule on Wednesday, August 19, Lee posted on X praising Trump’s move.

“I feel that President Trump’s message is a big decision reflecting the serious thought he put into creating peace beyond hostility and confrontation on the Korean Peninsula,” Lee wrote. He said Seoul shares Trump’s effort to create conditions for dialogue toward a peace regime, “even if that means scaling back the South Korea-U.S. combined exercises and field training,” and expressed respect for the decision.

Lee also vowed to act as a “pacemaker” supporting Trump’s “peacemaking” efforts and said he looked forward to meeting Trump again in the United States.

The response from the main opposition People Power Party (PPP) was swift and fierce.

Jang Dong-hyeok, the PPP leader, told a party meeting on Thursday, August 20, that Lee’s post was “a pitiful denial of reality” and “an unprecedented moral victory.” Jang argued the real cause of the crisis was Seoul’s “no thanks” to the Iran campaign and delays in U.S. investment commitments, not a grand peace initiative.

“What country’s commander-in-chief can be so gleeful after having its military training schedule with an ally bypassed?” asked PPP floor leader Jeong Jeom-sig earlier that day.

Jang warned that economic retaliation, including tariff hikes, would follow, and said “only North Korea, China and Russia will be smiling.” He accused Lee of abandoning security, diplomacy, and the economy.

Ruling party pushes back

On Friday, August 21, Democratic Party floor leader Han Byung-do defended Lee at a leadership meeting in Gangneung, calling the president’s approach a “responsible peace strategy” built on a solid Korea-U.S. alliance and strong self-reliant defense.

“President Lee expressed his respect for Trump’s determination to build a peace regime on the Korean Peninsula and said he fully agrees that South Korea must take responsibility for its own security,” Han said.

Han urged the PPP to stop “exploiting security anxieties” and questioned why opposition politicians attacked Lee while remaining silent on Trump’s decision.

Rep. Jin Seong-joon, who chairs the National Assembly’s National Defense Committee for the ruling party, argued that investment in the United States should be judged on commercial viability, not linked to joint exercises, and that Seoul should actively use the reduction as an opportunity given its own interest in dialogue with Pyongyang.

North Korea and alliance readiness

North Korea has largely dismissed the scale-back. State media said Pyongyang had no interest in the decision and that it did not change what it called the aggressive nature of the exercise. Kim Yo-jong, the North Korean leader’s sister, said the reduced exercise still left Seoul in a “poor plight” over continuing war games.

Analysts note the tension: North Korea has launched ballistic missiles since early August and deepened military cooperation with Russia, even as Trump seeks renewed diplomacy with Kim.

For Seoul, the canceled counterattack drills carry a separate worry. Field training is central to South Korea’s push for an expedited transfer of wartime operational control (OPCON) from Washington — a long-standing Lee priority, with a 2030 target he has publicly reaffirmed.

What comes next

The early end to UFS leaves several questions open:

• Whether postponed field maneuvers will be held separately or conducted by South Korea alone
• How Trump’s outreach to Kim and frustration with Seoul over Iran and investment will shape alliance consultations
• Whether Lee’s praise helps or hurts his planned follow-up meeting with Trump

Lee’s office has framed the president’s remarks as alignment with a peace-first security doctrine. The opposition sees them as confirmation that Seoul was sidelined by a unilateral U.S. decision — and that Lee chose rhetoric over alliance management.

Discussion

1. When an ally scales back joint drills without prior consultation, should Seoul publicly praise the move or push back?

Lee chose praise and a peace narrative. Critics say that signals weakness. Supporters argue it keeps dialogue channels open. Where should the balance fall?

2. Can reduced exercises lower tensions with North Korea without weakening deterrence?

Trump and Lee frame the cut as a confidence-building step. Opposition lawmakers and some defense analysts warn that canceled counterattack training and live events could erode readiness at a moment of missile tests and closer Pyongyang-Moscow ties.
