Key Takeaway

Deterioration of the U.S.-South Korea alliance means increased geopolitical risk for investors in East Asia, impacting regional stability. This directly translates to heightened uncertainty for technology supply chains, defense contractors, and manufacturing sectors reliant on a secure Indo-Pacific, potentially driving up costs and reducing investment.

A new analysis by Scott A. Snyder, Senior Fellow for Korea Studies and Director of the Program on U.S.-Korea Policy, reveals the U.S.-South Korea alliance, a seven-decade cornerstone of Indo-Pacific security, faces significant threats from rising exclusive nationalism and deepening political polarization in both nations, potentially impacting regional stability.

The book, 'The United States–South Korea Alliance: Why It May Fail and Why It Must Not,' thoroughly explores how these internal and external pressures could weaken the partnership, detailing the profound implications for the security strategies of both the U.S. and South Korea. It also examines the broader Northeast Asian security landscape, considering how a weakened alliance impacts regional dynamics, including relations with North Korea, China, and Japan.

The author hypothesizes a future without this critical alliance, outlining severe consequences for U.S. and South Korean security and economic interests. Ultimately, the analysis concludes with concrete recommendations for both countries to preserve and sustain the alliance amidst these complex and evolving challenges, emphasizing the necessity of cooperation over self-interest.
