South Korea-US defence talks in Washington: OPCON transfer, DMZ access on agenda
Synopsis
South Korea's push to reclaim wartime command of its own forces — held by the US since the Korean War — enters a critical phase next week in Washington. With a 2029 deadline now on the table, a DMZ access dispute openly opposed by the UN Command, and pressure over the Strait of Hormuz, the KIDD talks carry more strategic weight than any in recent memory.
Key Takeaways
The biannual Korea-US Integrated Defence Dialogue (KIDD) will be held in Washington from Tuesday to Wednesday next week.
Wartime OPCON transfer is the headline issue; Gen.
Xavier Brunson told Congress both sides aim to meet transfer conditions by Q1 2029 .
South Korea has held wartime operational command with the US since the 1950–53 Korean War ; peacetime OPCON was retaken in 1994 .
Seoul's proposal to control civilian access to the 250 km DMZ has been openly opposed by the UNC as "completely at odds" with the armistice agreement.

KIDD was launched in 2011 ; the previous session was held in September 2024 .
South Korea and the United States are set to hold high-level defence talks in Washington next week, with the wartime Operational Control (OPCON) transfer and civilian access to the inter-Korean buffer zone expected to dominate the agenda, Seoul's defence ministry confirmed on Thursday, 8 May 2025. The biannual Korea-US Integrated Defence Dialogue (KIDD) will run from Tuesday through Wednesday (US time), marking the first such meeting since September 2024.
Key Agenda Items
Kim Hong-cheol, Deputy Defence Minister for Policy, will lead the South Korean delegation, facing John Noh, US Assistant Secretary for Indo-Pacific Security Affairs, across the table. According to Seoul's ministry, the two sides plan to discuss "a broad range of alliance security issues, including the transfer of wartime OPCON and the combined defence posture, to ensure that the South Korea-US alliance develops in a future-oriented and mutually beneficial manner."
The Lee Jae Myung government has set a firm political objective: retake wartime command before its five-year term ends in 2030. Last month, US Forces Korea commander Gen. Xavier Brunson told Congress that both countries are working to meet the required conditions no later than the first quarter of 2029.
The Long Road to OPCON Transfer
South Korea handed over operational control of its forces to the US-led UN Command (UNC) during the 1950–53 Korean War. That authority was subsequently transferred to the Combined Forces Command (CFC) when it was established in 1978. Seoul retook peacetime OPCON in 1994, but wartime operational command has remained in American hands for over three decades.
The conditions for transfer include South Korea's demonstrated capability to lead combined Korea-US forces, its independent strike and air defence capabilities, and a regional security environment conducive to such a handover — a bar that analysts note remains a moving target given North Korea's accelerating nuclear and missile programmes.
DMZ Access Control: A Flashpoint With the UNC
Also high on the agenda is the question of civilian access to the southern side of the Demilitarised Zone (DMZ) — the heavily fortified 250-kilometre buffer stretching 3 km in width that separates the two Koreas. The Lee government is seeking control over civilian access to this zone as part of broader efforts to restore ties with North Korea.
Seoul has reportedly proposed jointly managing the area, currently administered by the UNC under the armistice agreement that ended the Korean War. Bills designed to grant the government control of nonmilitary access to the DMZ are pending in the National Assembly. Notably, the UNC has openly objected to these moves, stating they are "completely at odds" with the armistice agreement — a rare public rebuke from a multilateral command structure the US leads.
Strait of Hormuz and North Korea Deterrence
Next week's talks are also expected to address the Trump administration's calls for allied nations to help reopen the Strait of Hormuz, which has remained blocked since the US-Iran conflict. Washington has proposed an international coalition called the "Maritime Freedom Construct" to ensure free navigation of the vital waterway.
Seoul has so far stopped short of committing to military involvement, a stance that has reportedly drawn discontent from US President Donald Trump. This comes amid broader allied burden-sharing tensions that have defined Trump's second term.
The two sides are additionally expected to discuss bolstering deterrence against North Korea's evolving nuclear and missile threats, combined defence posture, and bilateral cooperation in the naval maintenance, repair and overhaul (MRO) market. Launched in 2011, KIDD serves as the primary senior-level comprehensive defence dialogue between the two allies.
Point of View
At its core, a sovereignty question Seoul has deferred for seven decades — and the Lee government's 2030 deadline gives it political urgency that previous administrations lacked. Yet the conditions-based framework means Washington retains effective veto power over the timeline, regardless of Korean political will. The DMZ access dispute is equally telling: the UNC's blunt objection to pending National Assembly bills signals that the US-led command structure is not prepared to cede administrative authority even in nonmilitary matters. Meanwhile, Seoul's reluctance on the Strait of Hormuz reflects a government caught between a domestic public wary of entanglement in Middle East conflicts and a Trump White House that views burden-sharing as transactional. The Washington talks will reveal how much room Seoul actually has to manoeuvre.

Frequently Asked Questions
What is the Korea-US Integrated Defence Dialogue (KIDD)?
KIDD is a biannual senior-level defence meeting between South Korea and the United States, launched in 2011 to address comprehensive alliance security issues. The previous session was held in September 2024, and the upcoming round is scheduled for next week in Washington.
What is wartime OPCON and why does South Korea want it back?
Wartime Operational Control (OPCON) refers to the authority to command South Korean forces during an armed conflict, which has been held by the US-led Combined Forces Command since the Korean War. Seoul retook peacetime OPCON in 1994 but wants full wartime command restored before the Lee Jae Myung government's term ends in 2030, viewing it as a matter of national sovereignty.
What conditions must be met before the OPCON transfer can happen?
The transfer requires South Korea to demonstrate the capability to lead combined Korea-US forces, possess credible independent strike and air defence systems, and a regional security environment conducive to the handover. US Forces Korea commander Gen. Xavier Brunson told Congress both sides are targeting no later than Q1 2029 to meet these conditions.
Why is the DMZ access issue contentious?
South Korea's Lee government wants civilian access control over the 250 km Demilitarised Zone to facilitate engagement with North Korea, but the area is currently administered by the UN Command under the Korean War armistice agreement. The UNC has publicly objected to pending National Assembly bills on the matter, calling them completely at odds with the armistice — a significant public disagreement between Seoul and the US-led command.
What is the Maritime Freedom Construct and how does it affect South Korea?
The Maritime Freedom Construct is a US-proposed international coalition to reopen the Strait of Hormuz following the US-Iran conflict. The Trump administration has pressed allies including South Korea to join, but Seoul has stopped short of committing to military involvement, reportedly drawing discontent from President Donald Trump.
