# Trump Revives 'Security Free-Rider' Claim: Shaking US-ROK Alliance, Will USFK Withdrawal Become Reality?
## [Background]: US-ROK Alliance Pushed to the Brink, The Chronic 'Security Free-Rider' Debate
The US-ROK alliance, a product of the Cold War, has been a cornerstone in safeguarding South Korea's security against North Korean threats and protecting America's strategic interests in East Asia. However, over time, conflicts have persisted between South Korea, comfortable under the American 'security umbrella,' and the United States, burdened by excessive defense costs. Former President Trump, advocating 'America First,' strongly criticized the 'security free-riding' of allies, including South Korea, demanding a substantial increase in defense cost-sharing, causing a severe rift in US-ROK relations. This conflict goes beyond mere economic issues, raising fundamental questions about the value and trust of the alliance, clouding the future of US-ROK relations. In the past, the Trump administration actually considered reducing USFK troops, pressuring the South Korean government, which amplified security anxieties in South Korean society. While US-ROK relations seemed to stabilize under the Biden administration, the return of former President Trump is once again foreshadowing turbulence in the Korean Peninsula's security landscape.
## [Current Situation]: Trump Enraged by Non-Participation in Hormuz Strait Deployment... USFK Withdrawal 'Under Consideration'
On April 2, 2026, local time, former President Trump, in an interview, reiterated the possibility of withdrawing USFK troops, arguing that South Korea is not sufficiently contributing to America's security efforts. He expressed explicit dissatisfaction with South Korea's passive attitude towards the recent request for deployment to the Hormuz Strait, stating, "The United States is spending enormous amounts of money to protect South Korea, but South Korea is not paying its fair share." Former President Trump's remarks can be interpreted as representing the views of hardliners within the Republican Party and may have a significant impact on future US foreign policy. An anonymous US Department of Defense official stated, "Former President Trump has been consistently reviewing plans to reduce USFK troops since his tenure, and his recent remarks are an extension of that stance." Furthermore, a Washington D.C. think tank researcher analyzed, "Former President Trump is likely to use USFK troops as a bargaining chip if South Korea does not act in accordance with America's strategic interests." Currently, the USFK troop size is approximately 28,500, playing a crucial role in maintaining security on the Korean Peninsula. If USFK troops withdraw as claimed by former President Trump, a security vacuum in South Korea is inevitable, which could exacerbate military tensions in Northeast Asia.
## [Multi-faceted Analysis]: Destructive Impact on Markets, Society, and Politics... Experts 'Warn'
Former President Trump's remarks immediately caused significant repercussions in domestic and international financial markets. The KOSPI index plummeted by more than 2% at one point during the day, and the won/dollar exchange rate soared. Investors expressed concerns about the negative impact of US-ROK alliance instability on the South Korean economy, strengthening the preference for safe-haven assets. Socially, security anxieties are spreading, and critical public opinion is rising regarding the government's foreign and security policies. In particular, the younger generation is expressing antipathy towards America's unilateral attitude, raising voices emphasizing the need for independent national defense. Politically, the blame game between the ruling and opposition parties is intensifying, and the next presidential candidates are fiercely competing, presenting various solutions for redefining US-ROK relations. Experts warn that former President Trump's remarks pose a serious threat to the foundation of the US-ROK alliance. A researcher at the Brookings Institution pointed out, "Former President Trump's remarks could instill deep distrust in South Korean society and undermine America's credibility as an ally." Furthermore, Professor Kim, an international political scientist, criticized, "Former President Trump is only viewing South Korea from an economic perspective and overlooking the strategic value of the US-ROK alliance." The withdrawal of USFK troops could have a significant impact not only on South Korea's security but also on the balance of power in Northeast Asia, which could lead to the expansion of China and Russia's influence.
## [Future Outlook]: South Korea's Lonely Choice, Strategic Reconsideration for Survival... AI 'Warns'
Former President Trump's revival of the 'security free-rider' claim means that South Korea has been put to a critical test. In the future, South Korea will have to choose between two options: succumbing to American pressure and substantially increasing defense cost-sharing, or strengthening its independent national defense capabilities and breaking away from American influence. If South Korea chooses to increase defense cost-sharing, it could place a significant burden on the South Korean economy, and America's demands are likely to continue without stopping here. On the other hand, if South Korea chooses to strengthen its independent national defense capabilities, it will require massive budget investment and technology development, and there is a risk of intensifying the arms race with neighboring countries. South Korea must embark on a strategic reconsideration for survival amidst this dilemma. It must reduce its dependence on the United States through diplomatic diversification, strengthen cooperation with neighboring countries, and increase its security independence by increasing its own military strength. In addition, efforts to build a peace regime on the Korean Peninsula through the resumption of dialogue with North Korea must also be pursued in parallel. Given the possibility of former President Trump's re-election, South Korea must prepare for the worst-case scenario and keep all possibilities open. AI coldly warns: "South Korea can no longer rest on America's 'protection.' If it does not pioneer its future with its own strength, it will disappear into the annals of history."
