President Donald Trump’s latest directive to reduce the scale of joint U.S.–South Korea military exercises has brought renewed focus to a partnership that has lasted more than seven decades. While the move echoes his first‑term approach, it occurs against a backdrop of heightened North Korean missile development and evolving U.S. strategic interests in the Indo‑Pacific.
North Korea policy and joint drills
Trump’s stance toward North Korea shifted dramatically from the “fire and fury” rhetoric of 2017 to personal meetings with Kim Jong Un in Singapore (2018), Hanoi (2019) and the Demilitarized Zone later that year. After the Singapore summit, he suspended the August 2018 Ulchi Freedom Guardian exercise, labeling it costly and provocative. Subsequent drills were either cancelled or restructured.
Following the collapse of Hanoi talks without a denuclearisation pact, North Korea accelerated its missile and nuclear programs. The allies have since reinstated larger exercises that now address emerging threats such as drones and cyberattacks. Trump’s newest order revives his earlier reduction strategy, noting that North Korea has expanded its arsenal, continues missile testing, and has deepened military ties with Russia. Despite this, Trump maintains that his relationship with Kim remains “good” and described North Korea as “unthreatening and respectful” during his presidency.
U.S. security commitment and cost‑sharing
Trump repeatedly questions the cost of stationing roughly 28,500 U.S. troops in South Korea, while affirming Seoul’s importance as an ally. His administration seeks to “modernise” the alliance, potentially granting U.S. forces greater flexibility to respond to challenges beyond the Korean Peninsula, particularly China. This creates tension for Seoul, which relies on Washington for North Korean deterrence but wishes to avoid entanglement in a conflict over Taiwan.
Under the current cost‑sharing agreement for 2026‑2030, South Korea will contribute about 1.52 trillion won (approximately $1.1 billion) this year toward U.S. troop upkeep. Trump continues to argue that Seoul pays too little, while South Korean officials insist the existing pact should be honoured.
Trade and investment issues
Trump’s first administration renegotiated the bilateral free‑trade agreement and imposed tariffs on South Korean steel. In his second term, broader tariff pressure resurfaced. Washington initially threatened 25 % tariffs before settling on a 15 % rate in exchange for South Korean investment commitments. Trump later threatened higher tariffs again, accusing Seoul of moving too slowly on implementation.
South Korean companies have invested heavily in U.S. semiconductors, batteries, electric vehicles, and shipbuilding. Seoul pledged $350 billion for U.S. projects in return for tariff relief, a sum Trump described as payable upfront. Seoul clarified that the funding would involve loans, guarantees, and equity, warning that a cash‑only payment could destabilise its economy.
Political dynamics
Trump’s two terms have coincided with liberal South Korean governments that favour engagement with the North. Former President Moon Jae‑in facilitated Trump’s diplomacy with Kim, though differences over sanctions occasionally caused friction. The conservative Yoon Suk‑yeol administration took a harder line on Pyongyang and deepened security cooperation with Washington and Tokyo. Currently, liberal President Lee Jae‑myung continues to seek lower tensions with North Korea while navigating Trump’s personalized diplomacy.
Seoul has also cultivated unconventional channels into the White House. During 2025 tariff negotiations, South Korean officials engaged directly with White House Chief of Staff Suzy Wiles to clarify Trump’s intentions. The appointment of Seoul‑born former Republican congresswoman Michelle Steel as U.S. ambassador to South Korea provides a politically aligned envoy as both governments manage differences over defense costs, tariffs, and investment.
