South Korea hosts America’s biggest overseas military base – but what does its future look like under Trump?

A Look into the Biggest American Military Base Abroad and its Uncertain Future

Imagine a place with American football fields, baseball diamonds, and school bus routes. A place where soldiers line up for lunch at fast food joints and English is the only language you see on signs. The US dollar is used to pay for goods in stores filled with American groceries. It would be easy to think this place is in the heart of America, but it's actually over 5,000km away from the mainland.

Located in Pyeongtaek, a city in South Korea, this mammoth military base is the largest the US has outside its borders. Spanning 1,372 hectares (3,390 acres), it houses nearly a thousand buildings and is home to about 41,000 people. This includes American service members, their families, and Korean nationals.

The Role of the Base in US-South Korea Relations

This base serves as the headquarters for the United States Forces Korea (USFK), representing the solid alliance between Washington and Seoul. This partnership has been the backbone of stability on the Korean peninsula since the Korean War ended with a ceasefire in 1953.

However, the alliance that enabled the establishment of this outpost is now under strain. The relationship has become more transactional than ever, causing concern in Seoul, which has relied on Washington for its defense against North Korea. The trust and credibility of this alliance seem to be deteriorating.

The announcement of the US president to withdraw 5,000 troops from Germany has led to speculation that South Korea might be next. This speculation has been a recurring theme throughout his tenure. Although the defense ministry and presidential office were quick to deny these rumors, and USFK insisted that the current 28,500 troops was a minimum, not a maximum, the speculation persists.

Tensions within the Alliance

During this period, other strains within the alliance have begun to surface, impacting national security. For instance, the sharing of intelligence was partially restricted after a South Korean minister publicly identified a suspected North Korean nuclear site. Meanwhile, the fallout from a data breach at an American company has held up talks on the development of nuclear-powered submarines.

As a result of these tensions, South Korea is reassessing its reliance on American protection.

The Unique Position of the Base

The base, despite its suburban appearance, is a military installation preparing for war. At the high-tech training center, US and Korean soldiers conduct water-survival drills in a pool designed to simulate a helicopter crash into the sea. Medical rooms filled with artificial smoke and combat sounds allow troops to practice battlefield evacuations. Virtual-reality simulators enable units to run combat scenarios in almost any country or terrain in the world.

The base is strategically located roughly 800km (500 miles) from Shanghai and under 1,400km from Taiwan, potentially giving the US a positional advantage that no other ally can provide. The commander of USFK believes that the base's presence complicates every decision an adversary makes.

Concerns in Seoul

However, in Seoul, there are fears that hosting a base for US operations beyond North Korea might pull South Korea into unwanted conflict with China. There's a strong worry about getting entangled in the broader strategic competition between the US and China, especially over potential Taiwan contingencies.

Recent calls for allies, including South Korea, to join US-led operations in the Strait of Hormuz have heightened these concerns. Despite these uncertainties, construction continues at the base with four new barracks nearing completion, and a new elementary school being built.

For now, the likelihood of large-scale troop withdrawals seems slim. A sculpture outside the USFK headquarters commemorates the US-South Korea alliance, inscribed with the words: "함께 갑시다" (hamkke gapsida) – we go together.
