The month-long audit, which concluded last week, brought several areas of disagreement into public view, including intelligence sharing, access to senior White House officials and delays in issuing US visas to South Korean lawmakers. The disclosures have prompted opposition criticism of President Lee Jae Myung's handling of relations with Washington.
One significant concern involves intelligence cooperation. South Korea's intelligence chief, Lee Jong-seok, acknowledged that Washington had restricted some sensitive intelligence sharing after accusing a South Korean minister of publicly disclosing the location of a previously unconfirmed North Korean nuclear site. Officials have not provided further details about the extent of the restrictions.
The dispute comes as the United States reassesses its military posture in the Indo-Pacific. Washington has maintained that approximately 28,500 American troops stationed in South Korea will continue to deter North Korea, while signalling greater flexibility for US forces to operate beyond the peninsula in response to regional threats, including a potential conflict involving Taiwan.
This shift presents a strategic dilemma for Seoul. South Korea relies on the US security commitment to deter North Korean aggression, but Washington's growing focus on China could place additional demands on its regional partners and alter expectations about their military responsibilities.
Economic and public concerns are also complicating the relationship. Trade and investment tensions have persisted, while previous immigration enforcement actions involving South Korean workers in the United States have contributed to public unease. A Pew Research survey published in August found that 55% of South Koreans viewed the United States unfavourably, the highest proportion in more than two decades.
The Democratic victory in the US midterm elections adds another political variable. Although a Democratic-controlled Congress could constrain aspects of the Trump administration's agenda, analysts do not expect it to remove pressure on Seoul to increase defence cost-sharing or support greater strategic flexibility for American forces.
South Korean officials have sought to portray the alliance as fundamentally stable, despite the disagreements revealed during the audit.
The challenge for both governments will be maintaining security cooperation while reconciling different priorities across the Korean Peninsula and the wider Indo-Pacific. How Seoul manages this adjustment could have implications for regional deterrence, trade relations and the balance of influence in East Asia.
