Why Does Reducing US Troops in Korea Matter?

Understanding the USFK Drawdown Debate

The ongoing discussion about the potential reduction of the United States Forces Korea (USFK) has sparked significant concern and debate among South Korean officials, military experts, and the general public. The Trump administration’s approach to the USFK has been marked by demands for a smaller troop presence, changes in the role of the forces, and increased financial contributions from South Korea. These discussions have evolved into a broader conversation about the future of the US military presence in the region and its implications for regional security.

What Are the Claims and Demands?

The Trump administration has expressed a desire to reduce the size of the USFK, adjust its role, and increase burden-sharing from South Korea. This was highlighted when the Wall Street Journal reported that the Pentagon was considering moving 4,500 of the approximately 28,000 USFK personnel to other bases in the Indo-Pacific, such as Guam. The report caused a stir within the Pentagon, leading to an immediate denial from both the Pentagon and the USFK. However, this unusual response underscored the sensitivity of the issue.

A report published by Defense Priorities, a national defense think tank, suggested that the majority of US ground forces and fighter jet squadrons in South Korea should be withdrawn, with the USFK reduced to around 10,000 troops. The report also recommended further reductions in the long term, focusing on shifting the role of US forces to better counter China’s influence in the region.

Why Would the US Want to Reduce Its Troop Presence?

According to the report by Dan Caldwell, a former senior adviser to the US Defense Secretary, one of the main reasons for reducing the USFK is the lack of unrestricted access to South Korean bases for operations elsewhere in the region. Caldwell argues that US forces stationed in South Korea could be sidelined during a regional conflict, making it more efficient to utilize them elsewhere. He suggests reorganizing US forces in East Asia to focus on deterring China and protecting US interests. This includes relocating forces to Guam, which is part of the second island chain, rather than the first island chain that includes Japan, Taiwan, the Philippines, and Borneo.

This strategy aligns with the broader US global strategy of containing China and refocusing efforts on the Indo-Pacific. Since the Obama administration, the US has been restructuring its foreign policy to prioritize competition with China, and this trend has continued under the Trump administration.

Will the Number of US Troops in Korea Be Reduced?

The number of USFK troops has been decreasing since the Korean War, and South Korea has never had a say in these decisions. Historical examples include the withdrawal of the 7th Infantry Division under the Nixon administration in 1971, which reduced the number of USFK troops by around 20,000. More recently, the US has continuously asked South Korea to cover the costs of stationing troops on the peninsula.

The US has also been adjusting the role of the USFK, expanding its responsibilities beyond deterring North Korea to playing a part in other regional conflicts. This shift has led to calls for South Korea to take on a greater share of the costs associated with maintaining the USFK.

Why Is the Trump Administration Pushing for a Reduction?

Trump has always been skeptical of US involvement in foreign affairs, and his administration has emphasized the need for allies to shoulder more of the burden. The Indo-Pacific strategy aims to contain and confront China with the help of allies, reducing the US’s military responsibilities and involvement in conflicts. This approach has been accelerated under the Trump administration, with demands for increased defense spending from South Korea.

During his first term, Trump pushed South Korea to increase its share of defense costs, suggesting that the country should pay up to $5 billion annually. His demands coincided with a shift in the role of the USFK, as outlined by Elbridge Colby, the undersecretary of defense for policy. Colby believes that the USFK should be used to keep China in check rather than focusing solely on deterring North Korea.

What Choices Does South Korea Have?

The drawdown of US forces in Korea is inevitable in the long run, and South Korea must be prepared for this change. However, there are concerns that increasing the burden on South Korea could lead to a situation where the USFK takes on roles that may not be in South Korea’s best interest. Some argue that allowing the USFK to play a more active role in conflicts involving China or Taiwan could weaken South Korea’s negotiating position and place it at risk.

There is a growing sentiment that South Korea should move away from the notion that the US military is indispensable on the Korean Peninsula. By adopting a more self-reliant and pragmatic approach, South Korea can work towards true self-defense and maintain a balanced relationship with the US.
