South Korean President Lee Jae Myung emphasized the importance of a robust alliance with the United States for national security, a day after U.S. President Donald Trump unexpectedly ordered a substantial reduction in joint military exercises.
Trump announced the decision via social media shortly before the annual Ulchi Freedom Shield exercises, a joint drill designed to enhance readiness against North Korean threats, were set to begin. Trump cited his relationship with North Korean leader Kim Jong Un and South Korea's refusal to join the U.S. action against Iran as reasons for his order.
The move, reportedly made without prior consultation with South Korea, has heightened concerns about the reliability of the U.S.-South Korean alliance, which was established during the Korean War. A diminished U.S. defense commitment could impact South Korea's security, as the nation lacks nuclear weapons and relies on the U.S. "nuclear umbrella" for protection against potential nuclear-armed North Korea. The U.S. maintains approximately 28,500 troops in South Korea.
Confidence in the U.S. has already been affected among some South Koreans due to previous U.S. trade disputes and immigration actions that led to the detention of South Korean workers. The Hankook Ilbo newspaper described Trump's announcement as revealing the "stark reality of a faltering Korea-U.S. alliance, fueling public anxiety" and criticized the U.S. for appearing to treat North Korea with more respect than its ally.
During a Cabinet meeting, President Lee stressed that a solid alliance would "further strengthen" national security, adding that "when we build up our strengths, our value and importance as an ally will further grow." Lee, known for advocating a stronger, self-reliant defense, did not specify which aspects of the 11-day exercises would be downsized.
Earlier statements from the South Korean and U.S. militaries indicated that this year's drills would be comparable in scale to previous years and would incorporate lessons learned from recent conflicts. North Korea's Foreign Ministry has accused South Korea and the U.S. of planning more provocative drills and has vowed a response of "a new level of a deterrent."
Experts suggest that Kim Jong Un is unlikely to engage in talks with the U.S. or South Korea soon unless significant concessions are offered. North Korea has recently expanded its nuclear arsenal and strengthened ties with Russia.
Lee's presidential office had previously expressed hope that a "friendly relationship" between Trump and Kim could lead to "meaningful dialogue" for peace on the Korean Peninsula, a stance that drew criticism from conservatives who argued it prioritized diplomacy over security concerns. A spokesperson for the main conservative opposition party stated that "South Korea’s security bulwark is being shaken to its very foundations."
In his social media post, Trump described the joint exercises as costly and sending an "inappropriate and hostile" signal to North Korea, which he characterized as "unthreatening and respectful" during his presidency. He also mentioned that South Korea declined to join the U.S. in the "denuclearization" of Iran.
Lee's office clarified that South Korea and the U.S. are in discussions regarding practical and military contributions to help restore freedom of navigation in the Strait of Hormuz.
Leif-Eric Easley, a professor at Ewha University in Seoul, commented that Trump views alliances as investments requiring regular returns, while South Korean leaders are navigating relations with the Trump administration through a framework of continuous renegotiation linking economic and security issues.
