South Korea hosts America’s biggest overseas military base
Camp Humphreys is a vital expression of the alliance between Washington and Seoul, but the nature of the partnership is shifting

TL;DR
- Camp Humphreys, the largest US military base outside the US, is located in Pyeongtaek, South Korea, and houses around 41,000 people.
- The base serves as the headquarters for United States Forces Korea (USFK) and represents the alliance between Washington and Seoul.
- The alliance is currently being tested by increasingly transactional relations under President Trump, causing unease in Seoul.
- Speculation about potential US troop reductions in South Korea has resurfaced, mirroring concerns raised by troop withdrawals from Germany.
- While USFK states troop numbers are a baseline, tensions have spilled into national security issues, including intelligence sharing and trade disputes.
- South Korea is reassessing its dependence on American protection amidst these evolving dynamics.
- The Pentagon's national defence strategy suggests South Korea could take primary responsibility for deterring North Korea with limited US support.
- Washington is also looking to expand the base's mission beyond the Korean peninsula, viewing South Korea's location as strategically advantageous for regional operations, particularly concerning China.
- However, there are fears in Seoul that reorienting USFK towards containing China could drag South Korea into unwanted conflicts.
- Despite concerns, the base is undergoing expansion, with new barracks and facilities under construction, suggesting no immediate large-scale troop withdrawals are planned.
