Trump’s “Transactionalist” Approach and its Implications for the ROK-US Alliance
President Donald Trump’s foreign policy, characterized by a focus on personal relationships and transactional deals, casts a long shadow over the future of international alliances, notably the critical ROK-US alliance. His blunt interactions with foreign leaders, exemplified by his confrontational stance towards Ukraine’s President Zelensky, signal a departure from conventional diplomatic norms and raise concerns about the reliability of US commitments.
“You don’t have a card”
This “transactionalist” approach, prioritizing individual relationships over established systems and national interests, coudl fundamentally alter the dynamics of the ROK-US alliance, a cornerstone of Korean security.
The Looming pressure to Contain China: A Potential Wedge in the Alliance?
The Trump governance is expected to exert meaningful pressure on South Korea to actively participate in containing China’s growing influence. This push aligns with the broader US defense strategy, spearheaded by figures like the US Defense Minister, who views China as the primary long-term security threat.

However, some analysts suggest that Korea is not considered a top-priority ally in this containment strategy. While voluntary participation is welcomed, the US may not heavily rely on South Korea, potentially diminishing the perceived importance of the ROK-US alliance. This shift could lead to a reevaluation of the USFK’s (United States Forces Korea) role, size, and deployment.
Currently, the US maintains approximately 28,500 troops in South Korea, a presence that has been a key deterrent against North Korean aggression for decades. Any significant reduction or change in the USFK’s mission woudl have profound implications for regional security.
Strategic Flexibility and the “Achilles Heel” of Camp Humphreys
The concept of “strategic flexibility,” allowing the US to utilize USFK forces in contingencies beyond the Korean Peninsula, particularly concerning China, remains a contentious issue. This raises concerns reminiscent of the pre-Korean War “Achison Line,” which excluded Korea from the US defense perimeter, potentially emboldening adversaries.

Furthermore, Camp Humphreys, the sprawling US military base in Pyeongtaek, could become a bargaining chip in negotiations over defense burden-sharing. South Korea has previously leveraged the base as leverage in discussions regarding US defense contributions. This creates a precarious situation were a vital security asset is subject to political maneuvering.
Given the unpredictable nature of the Trump administration’s foreign policy, South Korea must proactively develop “Plan B” scenarios to address potential shifts in the ROK-US alliance. This includes exploring alternative security arrangements, strengthening domestic defense capabilities, and engaging in broader regional diplomacy.
As Park Won-gon, Professor of north Korean Studies at Ewha Womans University, suggests, a thorough and adaptable strategy is crucial to safeguarding South Korea’s security interests in an increasingly volatile geopolitical landscape.
Camp Humphreys: A Shifting Strategic Asset in US Foreign Policy?

From Korean Stronghold to Potential Check on China: The Evolving Role of Camp Humphreys
Camp Humphreys,the world’s largest US overseas military base,located in South Korea,might potentially be poised for a significant strategic shift. Originally conceived as a state-of-the-art facility to consolidate US troops stationed across the Korean peninsula, its future role is now under scrutiny, potentially evolving from a bulwark against North Korea to a key asset in containing China’s growing influence.
The base, a sprawling complex three times the size of Yeouido, seoul’s well-known island, was inaugurated with much fanfare, even receiving a visit from then-President Trump in 2017. Equipped to house up to 85,000 personnel, it represented a significant investment in the US-South korea alliance. However, the changing geopolitical landscape and evolving US strategic priorities are prompting a re-evaluation of Camp Humphreys’ primary mission.
The ‘Leafman Gap’ and Shifting US Defense Priorities
The concept of the “Leafman Gap,” referring to the imbalance between a nation’s diplomatic and military goals and its available resources, is increasingly relevant to the US approach to its global commitments. As articulated by some US strategists, the US faces numerous global challenges and must prioritize its resources effectively. This has led to calls for allies to shoulder a greater share of their own defense burdens.
This shift is reflected in ongoing debates about defense spending and burden-sharing within NATO, where the US has consistently urged european members to increase their contributions to meet the agreed-upon target of 2% of GDP. A similar dynamic is now playing out in the US-South Korea alliance, with potential implications for the future of US military presence on the Korean peninsula.

Potential Missile Deployment and Regional Tensions
One potential scenario involves the deployment of missile systems at Camp Humphreys, a move that would undoubtedly provoke a strong reaction from China. Such a deployment could be interpreted as part of a broader US strategy to contain China’s growing military capabilities and assertiveness in the region. This strategy aligns with previous actions,such as the establishment of a missile defense network involving the US,South Korea,and Japan.
The deployment of THAAD (Terminal High Altitude Area Defense) in South Korea in 2017 already triggered significant tensions with China,leading to economic repercussions. deploying additional missile systems at Camp Humphreys could further escalate these tensions and potentially divide public opinion within south Korea.
Trump’s vision of foreign policy is a direction to give greater authority to the same competent and willing allies as korea.
Burden-Sharing and the Future of the US-South Korea Alliance
The US has been actively seeking to increase South Korea’s financial contribution to the upkeep of US forces stationed in the country. This push for increased burden-sharing has manifested in the form of new categories in defense cost negotiations, such as “Operation Support” and “Preparedness Postable” items. These categories encompass expenses related to the deployment of strategic assets to the Korean peninsula and the costs associated with joint military exercises.
This pressure on south Korea to shoulder a greater share of the defense burden reflects a broader trend in US foreign policy, where allies are expected to take on more duty for their own security. The future of the US-South Korea alliance will likely depend on how these issues of burden-sharing and strategic alignment are resolved.
South Korea’s Evolving Security strategy amidst North korean Threats and Geopolitical Shifts
By Archnetys News Team
South Korea faces an increasingly intricate security environment,demanding a multifaceted approach to defense. The persistent threat from North Korea, coupled with the shifting dynamics of US foreign policy and the rise of China, necessitates a re-evaluation of Seoul’s strategic posture.This includes bolstering independent defense capabilities, exploring trilateral cooperation, and carefully balancing its relationships with major global powers.
The North Korean Nuclear Threat and Extended Deterrence
the specter of North Korea’s nuclear arsenal looms large over the Korean peninsula. past joint military exercises between South Korea and the United States, designed to deter North Korean aggression, have come under scrutiny. These exercises, such as the combined training that concluded in August of last year, served as a presentation of extended deterrence, signaling that any North Korean use of nuclear weapons would be met with a decisive response.
The core of this strategy involves the deployment of US strategic assets, operating under concepts like “nuclear conventional integrated operation” (CNI) or “suppression of customized expansion,” in conjunction with South Korea’s conventional military strength.Any disruption to these joint exercises or the deployment of strategic assets could weaken the extended deterrence framework, potentially jeopardizing South Korea’s security.
Developing a “Plan B”: Strengthening Independent Defense Capabilities
Given the uncertainties surrounding future US foreign policy, particularly concerning the role of US Forces Korea (USFK), South Korea must develop contingency plans. Scenarios where large-scale US ground and air support might not be readily available necessitate a shift towards greater self-reliance. This requires a comprehensive “Plan B” that involves restructuring operational plans and building up indigenous military capabilities to effectively counter North Korea’s conventional and unconventional threats.
Increased defense spending is an unavoidable component of this strategy. According to the Stockholm International Peace Research Institute (SIPRI), global military expenditure reached a record high of $2.44 trillion in 2023,highlighting the growing investment in defense capabilities worldwide. South Korea must similarly prioritize defense investments to ensure its security in a volatile geopolitical landscape.
Balancing Act: China, the US, and regional Security
South Korea also faces the challenge of navigating the complex relationship between the United States and China.While Seoul seeks to maintain strong ties with Washington, it must also consider its economic and diplomatic relations with Beijing. The potential for US-led efforts to contain China, particularly concerning Taiwan, presents a delicate balancing act for South Korea.
While quietly consulting with the US and Japan on potential responses to a hypothetical Chinese attempt to seize Taiwan, South Korea must tread carefully to avoid antagonizing China.Public pronouncements or overt actions could damage its relationship with Beijing, highlighting the need for discreet diplomacy and strategic interaction.
korea is a secret consultation with the United states with Japan about the attempt to quickly capture taiwan by using force at the hearing. It is an extraordinary city. The challenge of security is more than ever. It is indeed sensitive, expensive and uncomfortable, and various homeworks are flocked. Korea must create an estimated problem and write an answer. It’s already too late.
Expert Analysis
According to Professor Park Won-gon, a North Korean Studies expert at Ewha Womans University, South Korea faces unprecedented security challenges that demand careful consideration and proactive planning. The need to anticipate potential problems and develop effective solutions is more urgent than ever.
