President Donald Trump instructed Secretary of Defense Pete Hegseth to "substantially reduce" the annual Ulchi Freedom Shield joint military exercises with South Korea, announcing the order on Truth Social hours before the drills were scheduled to begin [1][3][31]. Trump cited his self-described "very good relationship" with Kim Jong Un, the cost of the exercises, and South Korea's refusal to join US efforts to denuclearize Iran [4][8][18]. The order followed a proposal by South Korean President Lee Jae-myung for formal end-of-war talks with North Korea, adding a US policy shift to Seoul's diplomatic initiative [32].
Trump called the exercises "not only costly" but said they 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" [8][12]. He told reporters in the Oval Office that Kim Jong Un had responded to his outreach, saying "I understand him. He understands me" and "I'm actually making it much safer" [27][29]. Trump said he recently asked the South Korean president whether Seoul would join the denuclearization of Iran and was told "No thanks" [18][24][31].
South Korea's government responded with a split between its defense and political branches. The Ministry of Defence stated that the Ulchi Freedom Shield exercises would "proceed as previously notified and scheduled" [1][5][23]. The presidential Blue House said it was reviewing Trump's comments and "hopes that the friendly relationship between the US and North Korean leaders will lead to meaningful dialogue" aimed at advancing peace and stability on the Korean Peninsula [4][6][29][32]. South Korea's Joint Chiefs of Staff confirmed the drills began as scheduled [20].
South Korea's conservative opposition blamed President Lee Jae-myung's government for the crisis. Opposition leader Jang Dong-hyeok called the situation "a diplomatic disaster provoked by the Lee Jae-myung government itself" and said Lee "generates less trust from an allied president than the North Korean dictator" [14]. The main opposition party condemned the decision and accused the Lee administration of causing a security crisis and damaging the US-South Korea alliance [22].
Several outlets and analysts framed the decision as a punitive response to Seoul's refusal to back the US campaign against Iran. El Financiero reported that the announcement took Seoul by surprise and quoted analyst Adam Farrar warning that "this type of last-minute decision will generate questions about the US commitment to its Asian allies and could affect deterrence" [10]. Euronews' Persian-language service framed the decision through the lens of the US war with Iran, suggesting it may reflect depleted munitions and a desire to shift focus [41]. Bloomberg analyst Adam Parrott said the decision may reflect US frustration with South Korea over investment progress or refusal to support the Iran war [38].
US and South Korean military officials emphasized that this year's drills were designed around North Korea's contemporary battlefield experience. Col. Ryan Donald said the drills would simulate combat against North Korean troops "battle-hardened by deployment in the Russia-Ukraine war," with a focus on drone warfare, GPS disruption, and cyber attacks [4][6][29]. Lt. Gen. Scott Winter said the exercises were "bigger and better than ever" [21][29]. NORTHCOM Deputy Commander Lt. Gen. Joseph Jarrard warned that North Korea had tested intercontinental ballistic missiles with "enough boost to deliver a nuclear payload anywhere in North America" [8][30]. Retired South Korean Lt. Gen. Chun In-bum called the improvement in North Korean capabilities "very serious" and said "we should not take lightly this threat environment" [29].
Independent defense analysts warned that scaling back the drills would damage alliance coordination and weaken deterrence. Leif-Eric Easley, professor at Ewha University in Seoul, said the cost savings from downsizing drills "are marginal, while the diplomatic benefits for relations with North Korea are doubtful" [4][6][29]. Duyeon Kim of the Center for a New American Security said reducing joint drills "weakens military readiness over time against another potential North Korean attack" [6]. Mason Richey, professor at Hankuk University of Foreign Studies, called Trump's decision "absurd and irresponsible" [46]. Patrick Cronin of the Hudson Institute argued the decision undermines deterrence and readiness without altering Kim's calculations [34].
A bipartisan group of US lawmakers condemned the decision. Democratic Senator Jack Reed called it "another inane, haphazard decision" that punishes South Korea for declining to join a war Trump started and gives Kim a "propaganda victory" [6][8][30]. Republican Senator Thom Tillis warned that reducing exercises "does nothing more than free up thousands of North Korea's troops to support Putin's" war against Ukraine [30]. Democratic Senator Mark Kelly called hollowing out the exercises "shortsighted and a mistake" [16]. House Democrat Frank Pallone called Trump "truly unhinged" for thinking North Korea "is worth appeasing like this" [30].
Some analysts suggested the move may be part of a broader diplomatic strategy. Jenny Town of the Stimson Center said the decision "may be part of a larger effort to create a diplomatic opportunity with Pyongyang, as Trump has consistently wanted since coming back to office," though the "haphazard nature of this move is unlikely to make much of an impression in Pyongyang" [8][12][20]. Victor Cha of CSIS proposed that "Trump wants to engage Kim as a way to impede the Russia-NK ties" [12][34]. Christopher Green of the International Crisis Group said Trump "does seem to have been genuinely affronted by the fact that America's allies and partners did not jump to assist the United States in the conflict with Iran" [32].
North Korea's foreign ministry condemned the joint drills as "a rehearsal for an aggressive war" and warned that US-Japan-South Korea military cooperation "is turning into a nuclear alliance" to which Pyongyang will "respond to a new level of threat with a new level of deterrent" [1][4][17][29]. Korea-watchers predicted Pyongyang would remain unmoved by a partial drawdown. Kim Dong-yub of the University of North Korean Studies said North Korea "will likely say it has noted Trump's post but will wait for further action" [6]. Lim Eul-chul of Kyungnam University said "the North will only view it as meaningful if the joint exercises are cancelled in their entirety rather than scaled back" [29].
China's foreign ministry spokesperson Lin Jian called for "maintaining peace and stability on the Korean Peninsula and promoting a political solution," stating this "serves the common interests of all parties" [14][47]. South Korean progressive civic groups, including the 8·15 Independent Peace March Steering Committee, protested the Ulchi Freedom Shield drills before Trump's announcement, calling them aggressive and demanding their cancellation [39]. Cheong Seong-chang of the Sejong Institute argued that Trump's unilateral approach should prompt Seoul to gradually reduce its security dependence on Washington and move toward securing its own nuclear arms [29]. Some observers suggested domestic political considerations drove the announcement, with Lee Sang-ho of Daejeon University saying the main reason was to boost Trump's popularity amid the Iran conflict and upcoming midterm elections [24][47].
Defense Secretary Pete Hegseth had praised South Korea in May as a model ally on burden-sharing, calling it exemplary and saying "all of America's partners would do well to follow" it [16]. Former acting US Ambassador to South Korea Rob Rapson said the impact on short-term military readiness is likely minimal, citing the 2018 precedent when Trump similarly suspended drills [34]. The Pentagon confirmed it is working to execute Trump's order, according to Japan's Sankei Shimbun, which also reported Japanese government concern over a potential decline in deterrence [43]. The Pentagon spokesperson directed inquiries to the White House [20].
