South Korean President Lee Jae Myung says his country is ready to assume wartime operational control of combined South Korean and US forces, renewing a decades-long effort to place Seoul in charge of allied military operations during a conflict with North Korea.
Speaking to reporters at the Blue House presidential compound on Monday, Lee said discussions with Washington were progressing and that South Korea had the military capabilities needed to take over the command role. He said he wanted the transfer to happen as soon as possible, although he acknowledged that the process remained complicated after nearly 70 years of US-led operational command.
The transfer is a major objective of Lee’s administration, which aims to complete the process before his five-year presidential term ends in 2030. However, differences over military readiness assessments and the timeline suggest that the allies still have work to do before the transition can take place.
Why Does South Korea Want Wartime Operational Control?
South Korea’s wartime operational control arrangement dates back to the Korean War of 1950–1953, when command of the forces fighting under the United Nations Command was entrusted to the US military.

Although South Korea has developed its own substantial armed forces since then, the US continues to lead the combined allied command structure responsible for wartime operations on the Korean Peninsula.
Seoul and Washington agreed in 2007 to pursue the eventual transfer of operational control to South Korea. Successive South Korean governments have continued to pursue the objective, viewing it as an important step towards greater responsibility for the country’s national defence.
Under the proposed arrangement, a South Korean general would lead allied South Korean and US forces during a war with North Korea, rather than a US commander.
Lee has argued that South Korea is capable of assuming this responsibility despite North Korea’s development of nuclear weapons and ballistic missiles. He described nuclear weapons as fundamentally a means of final defence rather than conventional combat, while emphasising South Korea’s military strength.
However, transferring command would require more than a political agreement. The allies must assess whether South Korea can meet the operational requirements needed to lead combined forces in a conflict.
What Role Does the US Military Play in South Korea?
The United States maintains approximately 28,500 troops in South Korea, alongside military equipment and supporting capabilities intended to deter North Korean aggression.
The alliance remains central to security on the Korean Peninsula, where North Korea continues to develop nuclear weapons and ballistic missile capabilities. The two Koreas remain technically at war because the 1950–1953 conflict ended with an armistice rather than a peace treaty.
For Washington and Seoul, the command arrangement is therefore closely linked to military coordination, deterrence and the ability to respond to a potential conflict.
Any transfer must preserve the effectiveness of combined operations while ensuring that South Korea can assume the responsibilities currently exercised by the US-led command structure.
This makes the process sensitive for both allies. Seoul wants greater authority over wartime decision-making, while the two militaries must establish that command responsibilities can be transferred without undermining their joint defence posture.
Why Is the Transfer Timeline Disputed?
Although Lee wants to complete the transfer before 2030, the allies have not settled on a final timeline.
South Korean media reports have identified 2028 as Seoul’s preferred target year. However, US Forces Korea commander General Xavier Brunson has indicated that the security environment has changed since the allies established the conditions for transferring operational control.
Brunson told a US congressional hearing in April that the US military had submitted a roadmap aimed at meeting the relevant conditions by early 2029.
The difference between the reported timelines reflects the complexity of evaluating military readiness. The process involves determining whether South Korea can lead combined operations while maintaining effective coordination with US forces.
The allies have been discussing and assessing South Korea’s readiness, but their differing public statements indicate that the timetable remains a subject of consideration.
Lee’s remarks signal Seoul’s intention to maintain momentum, but the final decision will depend on the readiness assessments and agreement between both governments.
How Could the Transfer Affect Regional Security?
The proposed change comes amid continuing tensions between the two Koreas and wider concerns about security in Northeast Asia.
South Korea’s assumption of wartime operational control would give its military a more direct leadership role in a potential conflict, while the US would continue to contribute troops, equipment and military capabilities under the alliance.
The transfer would not, by itself, end the US military presence or terminate the defence partnership. Instead, it would change who leads the combined forces during wartime.
The practical implications would depend on how command responsibilities, operational coordination and decision-making procedures are organised under the revised arrangement.
North Korea’s nuclear and missile programmes remain a central consideration. Any transition must account for the demands of responding to conventional attacks and potential nuclear escalation while coordinating allied capabilities.
For Washington, the process also requires maintaining confidence that the combined defence structure can continue to deter aggression. For Seoul, it represents a longstanding effort to exercise greater control over the country’s wartime defence.
What Happens Next?
The next stage will centre on continued discussions between South Korean and US officials and assessments of whether Seoul has met the conditions required to assume wartime operational control.
Lee’s government is seeking a transfer before 2030, while the US military’s reported roadmap points towards early 2029 for meeting the relevant conditions. Whether the transition can occur within either timeline will depend on the outcome of the readiness process.
The broader challenge is to reconcile South Korea’s demand for greater command authority with the operational requirements of an alliance designed to respond to a potential North Korean attack.
For Seoul and Washington, the objective is not simply to change the identity of the wartime commander. It is to ensure that the transition preserves military coordination and deterrence while giving South Korea a greater leadership role in its own defence.
