Story summary
US President Donald Trump announced on Sunday that he would be scaling back US military exercises with South Korea, citing his "very good" relationship with North Korean leader Kim Jong Un and claiming that the exercises were expensive. The annual drills, known as Ulchi Freedom Shield, were originally scheduled to run from August 13-27, but have been reduced in scope and scale at the direction of Trump and Defense Secretary Pete Hegseth.
The decision has caused alarm among South Koreans, who rely heavily on the US for their security, as well as other US allies in the region. North Korea has been threatening a "new level" of nuclear deterrence in response to the planned drills, which Pyongyang state media called "a rehearsal for an invasion war."
South Korean President Lee Jae Myung, who had previously floated the idea of reducing joint military exercises with the US as a tool for drawing North Korea back to the table, has renewed his calls for wartime operational control of the military and progress on South Korea's nuclear submarine programme.
The decision to cut short the drills marks a significant shift in Trump's approach to North Korea, which he had previously criticized for its missile tests and threats. Trump added that US involvement in the exercises would send a "signal that is totally inappropriate and hostile" to North Korea, which he said has been "unthreatening and respectful" to his presidency.
The move has also sparked concerns among analysts and US senators about Trump's willingness to prioritize North Korean denuclearization over South Korea's security. Some have criticized Trump's approach as naive, citing the recent spate of North Korean missile tests and threats.
