USFK commander warns against 'political expediency' in rushed OPCON transfer

Remarks by the top U.S. military commander in South Korea have prompted a fresh round of debate over the planned transfer of wartime operational control (OPCON) from Washington to Seoul, with experts cautioning against letting political timelines override military conditions.

Gen. Xavier Brunson, commander of U.S. Forces Korea (USFK), emphasized a conditions-based approach to OPCON during testimony before the U.S. Senate Armed Services Committee on Tuesday (local time), urging that “political expediency does not outpace the conditions.”

His use of the phrase “political expediency” — a departure from his earlier, broader references to conditions — is being interpreted by analysts as a message aimed at slowing the momentum for OPCON transfer under Seoul’s current policy direction.

The Lee Jae Myung administration has made completing OPCON transfer within its five-year term a policy priority, with 2028 widely discussed as a possible target year.

That timeline has raised concerns that political considerations could begin to shape what has traditionally been a conditions-based process.

Brunson also emphasized a broader shift in how U.S. forces are being structured, saying, “My focus remains strictly on capabilities over numbers.”

Describing the Korean Peninsula as “a critical strategic nexus for defending the U.S. homeland and advancing American interests in the region,” he said its role should be reinforced to not only deter North Korea but also support a wider regional strategy, which is often interpreted as containing China.

These remarks point to a reassessment of the U.S. military’s presence in Asia, where adaptability and capability are becoming more important than troop numbers.

Cha Du-hyeogn, vice president of the Asan Institute for Policy Studies, questioned the logic of setting a fixed timeline in this context.

“What is the point of pushing for OPCON transfer based on a preset timeline?” Cha said. “The nature of war on the Korean Peninsula has shifted to include nuclear dimensions, but the existing conditions do not fully reflect that reality.”

Cha argued that the current framework, which is based on a three-stage verification process, was originally designed with conventional conflict in mind and may therefore not fully capture today’s security environment.

He warned that focusing on the timeline without reassessing the underlying conditions could pose a strategic risk.

Other experts pointed to broader strategic considerations in Washington.

“Washington has little reason to hold onto wartime OPCON and would prefer to transfer it sooner rather than later,” said Cho Han-bum, a senior research fellow at the Korea Institute for National Unification.

He also noted that USFK is increasingly viewed as part of a regional force posture tied to competition with China rather than focused solely on North Korea.

At the same time, Cho highlighted a potential gap between civilian and military perspectives in the U.S.

“There is a difference between the U.S. administration and the military,” he said, explaining that while policymakers may prioritize cost and efficiency, military leaders tend to focus on operational readiness and conditions.

This underlines the likelihood that political decisions, not just military assessments, will determine the pace of the transfer.

Kim Yeoul-soo, a senior researcher at the Korea Institute for Military Affairs, agreed, noting that OPCON transfer is not determined by capability alone.

“OPCON transfer is a matter of both capability and political will,” Kim said, adding that the timeline could accelerate or slow depending on decisions made in Washington.

Despite such concerns, some analysts urged against overstating the risks.

Retired Lt. Gen. Chun In-bum said deterrence on the Korean Peninsula would remain intact even if command arrangements change.

“The presence of U.S. forces itself is a deterrent, and that capability does not change,” Chun said, emphasizing that operational effectiveness matters more than formal command structures.

Beyond OPCON, Brunson addressed other issues related to U.S. force posture during the Senate hearing.

Responding to media reports about the redeployment of a Terminal High Altitude Area Defense (THAAD) system from South Korea to the Middle East, he said, “We’ve not moved any THAAD systems. So THAAD still remains on the (Korean) peninsula.”

He added that some munitions were being prepared for transfer, suggesting that while the system itself remains in place, certain assets could be repositioned as part of broader operational planning.

Brunson also pointed to evolving threats from North Korea, saying, “We are seeing a more experienced military” — an apparent reference to combat lessons the North has learned from overseas deployments, including in Russia’s war against Ukraine.
