US President Donald Trump directed the Pentagon to substantially cut the 2026 Ulchi Freedom Shield joint military exercises with South Korea. Originally scheduled from August 17 to August 27, the drills are now set to end on August 21, six days earlier, reducing the scope at the US's request. The exercises involve about 18,000 South Korean troops alongside US forces [1, 2, 3].

Trump cited his "very good relationship" with North Korean leader Kim Jong Un as a key factor for scaling back the drills, which he described as "not only costly" but also "sending a signal that is totally inappropriate and hostile" toward North Korea. He characterized North Korea as unthreatening and respected under his presidency [1, 2, 3, 4]. He said, "Based on my very good relationship with Kim Jong Un, I am not happy with the fact that the United States has, long ago, agreed to participate in Joint Military Exercises with South Korea" [4].

Trump also linked the decision partly to South Korea's refusal to help with US efforts to denuclearize Iran. He recalled asking South Korea's president about joining the campaign and being told, "No thanks!" [2].

South Korean officials, including Foreign Minister Cho Hyun, said neither their government nor US officials were informed in advance of the reduction. Cho stated, "Neither South Korean nor US officials had been aware in advance about Trump's plans to reduce the exercises" [2].

The US maintains approximately 28,500 military personnel in South Korea as part of longstanding security cooperation [2, 4]. This year's Ulchi Freedom Shield drills were expected to integrate lessons from North Korea's military support for Russia in Ukraine, including countering drones, GPS disruption, and cyberattacks [5, 6].

Trump has a history of scaling back or suspending joint US-South Korea exercises during his first presidential term to encourage diplomacy with Pyongyang [7].

The shortened Ulchi Freedom Shield exercises began on August 17 as planned despite the announcement but are scheduled to conclude on August 21, six days before the original end date of August 27 [2, 5].
