South Korea's Grand Strategic Shift

Abstract

South Korea is undergoing a significant transformation in its grand strategy, shifting from a posture of strategic ambiguity toward one of strategic clarity. This transition is prompted by several factors, including the intensifying rivalry between the United States and China, the evolving threat from North Korea, and a growing domestic consensus in favor of a more proactive international role. The strategic vision and Indo-Pacific Strategy under the Yoon Suk Yeol administration exemplify this new orientation, highlighting a principled alignment with the U.S. and other democracies, a commitment to upholding the rules-based international order, and an expansion of regional engagement. This transformation is evident in stronger alliances, notably with the U.S. and Japan, as well as a more robust defense posture focused on deterrence and technological innovation. Although the concept of grand strategy for middle powers is still a topic of debate, South Korea’s evolving trajectory demonstrates a coherent, long-term adjustment to a dramatically changing strategic landscape. The shift to strategic clarity, initiated under conservative leadership, appears to be ongoing even under progressive government, indicating that this change is more about structural adaptation than partisan preference. However, there are challenges to this strategy, including domestic polarization, ongoing threats from North Korea, and demographic decline, all of which test the sustainability of this new paradigm. Successfully addressing these issues will be critical for South Korea’s ability to maintain its strategic clarity and contribute to regional and global stability in an era of heightened uncertainty.
