South Korean President Lee Jae Myung is accelerating efforts towards defense self-reliance following US President Donald Trump's decision to scale back annual military drills. Lee called for faster progress in regaining wartime operational control (OPCON) of South Korean forces from the United States and for the development of nuclear-powered submarines. These initiatives are intended to enhance South Korea's defensive capabilities. Analysts suggest these actions stem from Seoul's increasing concern about the unpredictability of the US alliance under the current US president. The president aims to bolster South Korea's ability to defend itself while still maintaining the alliance with the United States.
