Elbridge Colby, U.S. Deputy Secretary of Defense for Policy / News1

On Monday, Elbridge Colby, the U.S. Deputy Assistant Secretary of Defense for Strategy and Force Development who played a key role in crafting the new National Defense Strategy (NDS), is set to engage in high-level talks with South Korean officials. His schedule includes a breakfast meeting with Foreign Minister Park Jin, followed by discussions with Defense Minister Lee Jong-sup on critical bilateral security matters. Sources indicate Colby may also confer with National Security Advisor Kim Sung-han.

Colby's visit to Seoul is particularly significant as it comes on the heels of the Pentagon's January 23 release of the NDS. The strategy notably asserts that South Korea has developed sufficient capabilities to take a more prominent role in deterring North Korean aggression, albeit with reduced U.S. support. This underscores Washington's push for Seoul to bolster its conventional deterrence capabilities.

<em>News1</em> reports that Colby, who arrived in South Korea on January 25, has a packed itinerary. After morning meetings with top South Korean national security officials, he is expected to engage with a local think tank and tour Camp Humphreys, the sprawling U.S. military installation in Pyeongtaek.

During his talks with South Korean leadership, Colby is likely to address several key issues, including calls for increased defense spending, the transfer of wartime operational control (OPCON), and South Korea's aspirations for nuclear-powered submarines. Analysts anticipate that Colby's approach will reflect the Donald Trump administration's emphasis on allies shouldering more of their defense burden and boosting cost-sharing.

The recent unveiling of the NDS has sparked speculation that the timeline for the OPCON transfer, a long-standing goal of the South Korean government, may be accelerated. This transition involves a comprehensive evaluation of whether a future South Korean-led Combined Forces Command can effectively conduct operations. Currently, the U.S. and South Korea are awaiting the final full mission capability (FMC) verification.

Notably, the NDS signals a pivot in U.S. military strategy, prioritizing homeland defense and deterrence against China. This shift has prompted discussions about potentially expanding the role of U.S. forces in South Korea beyond their traditional North Korea-focused mission to encompass broader Indo-Pacific security objectives.

Throughout the Trump administration, Colby has been a vocal proponent of South Korea assuming greater conventional defense responsibilities and increasing its defense expenditure. In a July tweet, he praised South Korea as an exemplary ally, noting its efforts to take a more proactive role in defending against North Korean threats and its consistent leadership in defense spending among U.S. allies.

Following his three-day visit to South Korea, Colby is scheduled to travel to Japan on Tuesday. There, he is expected to emphasize the critical importance of trilateral security cooperation between the U.S., South Korea, and Japan in addressing regional challenges.
