Camp Humphreys, located in Pyeongtaek, South Korea, stands as the largest overseas US military base globally, serving as a critical expression of the enduring alliance between Washington and Seoul. The sprawling complex operates much like a small American town, featuring school bus routes, baseball diamonds, and American football fields. Soldiers and their families have access to familiar US eateries such as Taco Bell, Pizza Hut, and Arby's, while a US postal service postbox and a commissary stocked with American groceries underscore its distinctly American character. All signage within the base is in English, and the US dollar is the primary currency used.
This extensive infrastructure highlights the deep integration of US forces within South Korea's defence strategy, a partnership forged in the aftermath of the Korean War. The presence of approximately 28,500 US troops in South Korea is a cornerstone of regional security, particularly in deterring aggression from North Korea. For decades, the alliance has been a stable element in the complex geopolitical landscape of East Asia, with both nations contributing to its maintenance and operational costs.
However, the future of this vital partnership faces potential shifts, particularly under the prospect of a second term for former US President Donald Trump. During his previous presidency, Trump repeatedly questioned the cost-sharing arrangements for US forces stationed abroad, including in South Korea. He pressed Seoul to significantly increase its financial contribution towards the upkeep of US troops, leading to contentious negotiations and raising concerns about the stability of the alliance.
A renewed focus on 'America First' policies could see similar demands resurface, potentially leading to further pressure on South Korea to bear a greater financial burden or even a reconsideration of the scale of the US military presence. Such changes would not only impact the direct operations of bases like Camp Humphreys but could also have broader implications for regional security dynamics, potentially influencing North Korea's strategic calculations and the stability of the Korean Peninsula.
For the United Kingdom, which maintains strong diplomatic and economic ties with both the United States and South Korea, any significant alteration to this alliance would be closely monitored. The Foreign, Commonwealth & Development Office (FCDO) consistently advises British nationals travelling to or residing in South Korea to monitor local security developments, particularly concerning North Korea. The stability of East Asia is a factor in global trade and security, and shifts in key alliances could have ripple effects on international relations and economic confidence.
