Trump announces reduction in joint military exercises

President Donald Trump announced on Sunday that the United States would reduce military exercises with South Korea, citing his positive relationship with North Korean leader Kim Jong Un and Seoul's lack of assistance with US efforts against Iran.

In a post on Truth Social, Trump wrote: "Based on my very good relationship with Kim Jong Un, of North Korea, I am not happy with the fact that the United States has, long ago, agreed to participate in Joint Military Exercises with South Korea. 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."

Trump also raised his request for South Korean support on Iran, writing: "While somewhat unrelated (?), I recently asked the President of South Korea if they would like to join us in the Denuclearization of the Islamic Republic of Iran, and they said, 'No thanks!'"

The exercises in question, called Ulchi Freedom Shield, were set to begin Monday and were originally scheduled for 11 days. According to reports, they have been shortened to five days. Trump later told reporters: "We have 39,000 soldiers over there, guarding you from Kim Jong Un, your next-door neighbour, and you're not going to help us on a very easy military operation in Iran. That's strange."

Historical context: Trump's first-term moves

This is not the first time Trump has scaled back exercises with South Korea. During his first term, the United States and South Korea reduced joint operations as part of an effort to ease tensions with North Korea. In 2018, Trump suspended major exercises after his first summit with Kim, citing cost and provocation. That year, he said it was "inappropriate to have war games" on the Korean Peninsula during nuclear negotiations.

In March 2019, after a failed Trump-Kim summit in Hanoi, the annual large-scale exercises were reconfigured into smaller ones. In 2019, Trump said: "The reason I do not want military drills with South Korea is to save hundreds of millions of dollars for the U.S. for which we are not reimbursed."

Trump and Kim met three times during Trump's first term, including a historic summit in Singapore in 2018 and at the DMZ in 2019. Trump has had a warm relationship with Kim despite North Korea being a longtime adversary of the United States. Earlier this weekend, he posted a picture of him and Kim with the caption: "Despite the unfriendly look on this particular picture, there are many where we're smiling, Kim Jong Un and I get along GREAT!"

North Korea's response

North Korea has long demanded an end to the drills, which it has described as preparations for invasion. Last year, its Central Military Commission called trilateral exercises with Japan and South Korea "the most comprehensive and offensive war drill for aggression in terms of scale, content and nature."

Ahead of the exercises, North Korea conducted two ballistic missile tests, which state media branded "a rehearsal for aggressive war." Later, Kim Yo Jong, the sister of Kim Jong Un, said she was "completely unaware" of Trump's claims that the two sides were communicating and dismissed the reduced exercises as still provocative. She acknowledged that her brother and Trump still have an "excellent" relationship. North Korea conducted missile launches on Thursday following her comments.

Analysts weigh motivations and implications

Analysts offered a range of interpretations for Trump's move. Some suggested he may be seeking a foreign policy success before the November mid-term elections, given that his efforts to resolve the conflict with Iran have stalled. Dr Nah Liang Tuang, an RSIS research fellow, said Trump's foreign policy record during his second term has been "lacklustre or unsuccessful."

Others pointed to possible strategic calculations, such as using the drills as a bargaining chip to bring North Korea back to negotiations, or pulling Kim away from Russian President Vladimir Putin. Dr Victor Cha, of CSIS, said the scaling down of drills is "a concrete action rather than just words," and suggested Trump may want to change the conversation from Iran to something else.

Dr Jaehan Park, also from RSIS, speculated that the Lee administration may have had some say in Trump's decision, but that Seoul was not informed in advance. South Korean President Lee Jae Myung has pushed for South Korea to gain greater independent control over its military, and has proposed talks with Pyongyang to replace the Korean War armistice with a formal peace arrangement. (The Korean War ended with a ceasefire rather than a peace treaty, meaning the two Koreas remain technically at war.) South Korean Foreign Minister Cho Hyun said Trump was trying to pressure Seoul on several issues, including its investments in the US.

The move has also raised concerns among allies and experts. Retired Rear Adm. Mark Montgomery, a senior fellow at the Foundation for Defense of Democracies, said canceling exercises decreases US readiness and puts troops at risk. He argued that Kim is not going to give up his nuclear weapon or make a deal for a Nobel Prize, noting that Trump's first-term meetings with Kim "made no impact whatsoever" and that Kim has increased his nuclear weapons yearly, now estimated to have 50-60 warheads.

Montgomery also highlighted the broader axis of adversaries, noting that Russia has helped North Korea build more accurate intercontinental missiles, and that North Korea has sent artillery shells, missiles, and tens of thousands of troops to help Russia in Ukraine. He said the axis has helped Iran, ties up the US military, distracts Europe, and makes the US less able to defend Taiwan.

Others cautioned against reading too much into the move. Dr Chang Jun Yan noted that the scale of exercises has reduced over the years; a decade earlier, participating troops were about twice as large. The shortened exercise, he said, is less about six days of training lost than what it represents.

Regional security implications

The US military exercises have been an important demonstration of Washington's commitment to its allies, and other US allies in the region will be watching closely. Dr Park noted that similar debates about Washington's reliability were emerging in countries such as Japan. East Asian states may increasingly become more self-reliant on national security, he said, and expediting the debate over wartime operational control could alter significantly the regional security architecture.

The pressing question for Seoul, as the South China Morning Post put it, is how much the country should continue to stake its security on a guarantee that Washington increasingly treats as negotiable.
