US Senate Tightens Oversight on Wartime OPCON Transfer to Seoul

Readiness before politics

: US Senate moves to tighten oversight of wartime OPCON transfer to Seoul

The annual US defense bill recently submitted to the full Senate by the Senate Armed Services Committee includes a provision to strengthen congressional oversight of the transfer of wartime operational control to South Korea.

The new provision in the fiscal 2027 National Defense Authorization Act requires the US defense secretary, beginning in March next year and every 90 days thereafter through 2030, to submit reports to the relevant congressional committees on the progress of the wartime OPCON transition roadmap.

It also requires the commanders of the US Pacific Command and US Forces Korea to each conduct an independent risk assessment of the wartime OPCON transition and submit it to Congress.

This suggests that Congress intends to closely scrutinize the wartime OPCON transition process and exercise direct oversight of it.

This also appears to reflect concerns in Washington that, amid the increasingly precarious security situation on the Korean Peninsula, wartime OPCON could be transferred for political reasons rather than based on military deterrence considerations.

The United States is not opposed to the transfer of wartime OPCON. The issue is the differing views between Seoul and Washington on the pace of the transition.

Last month, President Lee Jae Myung told Defense Minister Ahn Gyu-back that "it would be accurate to say there would be no problem whatsoever even if wartime OPCON were transferred tomorrow," signaling his desire to complete the transfer before the end of his term.

The Lee administration intends to seek to bring forward the transfer of wartime OPCON to next year at the annual South Korea-US Security Consultative Meeting later this year.

However, the US view is different.

US Forces Korea Commander Gen. Xavier Brunson said in April that South Korea and the United States aim to meet the conditions required for the transfer of wartime OPCON no later than the first quarter of 2029. Brunson said that "political expediency does not outpace the conditions" required for the transfer.

Robert O'Brien, the former White House national security adviser who served as the top national security official during Donald Trump's first term, said at a forum in Washington on June 18 that whenever politicians intervene and pull this issue (the wartime OPCON transfer) outside the military's area of expertise, things tend to go awry.

David Weiszol, deputy assistant secretary of state for East Asian and Pacific Affairs, said that the United States has consistently emphasized a conditions-based approach to South Korea to ensure that no vulnerabilities are left for adversaries to exploit.

The Lee administration should heed these warnings from Washington.

Currently, South Korea and the United States are conducting the second of three verification stages for the transfer of wartime OPCON.

There is speculation that the final stage of the process — the Full Mission Capability assessment — could be brought forward despite the fact that the ongoing verification of the future Combined Forces Command's Full Operational Capability has not been completed.

However, even if Seoul and Washington reach an agreement, a wartime OPCON transfer that bypasses the verification process would be neither feasible nor desirable unless it can clear US congressional oversight.

While wartime OPCON is a right that a sovereign nation should hold, its transfer must take place at precisely the right time, without creating even the slightest vulnerability in South Korea's security.

North Korea's nuclear and missile capabilities continue to advance, and cooperation among North Korea, China and Russia is growing stronger. At times like these, the stability of the South Korea-US alliance and the combined defense posture must remain steadfast.

While the transfer of wartime OPCON has symbolic value as a restoration of military sovereignty, what matters more is credible deterrence.

A wartime OPCON transition driven by political considerations would be a highly dangerous gamble that could create a gap in the nation's security.
