# South Korea's converging threats In South Korea, it’s easy to be complacent regarding the future of the region. Despite intermittent boil-overs, the stability lid has stayed on the pot. This is changing. Complacency will soon give over to concern with three steadily growing threats: contest, miscalculation, and uncertainty. These threats are not new. Each represents a known and understandable risk. **Contest** Geographical and arguably historical and cultural differences between the northern and southern regions of the Korean Peninsula do predate its modern division, but the modern political and territorial contest unarguably emerged from the postwar settlement of 1945, and the peninsula’s division into Soviet and American zones. The establishment of two competing states three years later institutionalized the division; and the war and its armistice, along with repeated failures to establish a more permanent diplomatic settlement, led to the enduring contest. Although the nature and intensity of the contest have changed over time, its underlying foundations remain: competing claims to political legitimacy, incompatible visions of the peninsula’s future, and the unresolved question of territorial sovereignty. Contest is about to return. The collapse of the Soviet Union, North Korea’s economic collapse, and the devastating famine of the 1990s left Pyongyang struggling for survival, while South Korea established overwhelming conventional military superiority. North Korea’s development of nuclear weapons offset this imbalance. Economic revitalization and military cooperation with Russia, and direct involvement in the war in Ukraine, have provided access to new technologies, operational knowledge, and battlefield experience, have now offset the conventional imbalance. On top of this, North Korea itself recognizes that its future is far from assured. Its efforts to emphasize the differences between North and South Korea and entrench their long-term separation, including the abandonment of reunification as a national objective, the designation of South Korea as a hostile state, and the physical destruction of inter-Korean transport links, reflect concerns about an externally imposed settlement of the peninsula’s division. To many in North Korea, the fear is that China could in fact prefer dealing with a unified Korean Peninsula under South Korean rather than North Korean rule, if the U.S. were to leave. **Miscalculation** Miscalculation has become a recognized feature of the Korean Peninsula. Ideological division, mutual distrust, limited communication, and the absence of reliable mechanisms for managing crises, have created an environment in which intentions are easily misunderstood and actions misinterpreted. Donald Trump adds an additional layer. Trump’s rhetoric with its exaggeration, imprecision, and provocation, is more game show host than head of state. He cannot distinguish domestic and international politics, negotiation, or policy. In 2017, this was evident in his threats of “fire and fury” and the “total destruction” of North Korea, followed by the abrupt shift to personal diplomacy. That was ten years ago. His capacity to distinguish political performance and state policy has only decreased. On a peninsula where miscalculation can lead to war, the inability to distinguish rhetoric from intent is itself a dangerous source of instability.  **Uncertainty** East Asia is entering a period of strategic uncertainty: after Ukraine and Iran, the US will either leave or contest East Asia—this will transform the region. If the U.S. contests East Asia, Korea will be at the center. The peninsula remains the point at which American maritime power meets Chinese and Russian continental power, with North Korea and South Korea providing the opportunity and instrument for challenging the regional order. Any sustained American effort to preserve its regional primacy will necessarily involve Korea, its military infrastructure, its alliances, and its unresolved political and territorial divisions. If the U.S. leaves East Asia, Korea will again be at the center. The withdrawal of American power would fundamentally alter the balance between continental and maritime powers, exposing South Korea to new risks and opportunities. How these changes will impact South Korea remains uncertain. The only certainty is that Korea will be at the center of them. On top of this, North Korea faces its own challenges. Economic growth doesn’t necessarily strengthen control. It generates rising expectations, inequalities, and dissatisfaction. The return of veterans from Ukraine present another challenge. Returning soldiers possess combat experience, military expertise, as well as shared experience, personal networks, and a stronger capacity for coordination outside structures of authority. Additionally, North Korea will sooner or later face the challenges of political succession. Stability in North Korea cannot be taken for granted. **Threat convergence** Contest, miscalculation, and uncertainty, are not new threats. However, such a degree of simultaneity has not been seen since the Korean War. This fact is not insignificant. The Korean War (1950–1953), much like the Russo-Japanese War (1904–1905) and the First Sino-Japanese War (1894–1895), was a contest that settled transformations in the balance between continental and maritime powers. Japan’s capacity to contest the continental-maritime balance derived from the adoption of Western industrial technologies, particularly steam-powered warships, modern artillery, repeating rifles, railways, and telegraph communications. These technologies fundamentally altered the balance of power between Japan and Qing China, culminating in Japan’s victory in the First Sino-Japanese War (1894–1895). In Ukraine and Iran, we have seen the same changes take place. This time, the continental-maritime balance is tilting to the former. Changes in technology, including drones and autonomous systems; precision-guided missiles; satellite reconnaissance, communications, and navigation targeting; and digital command-and-control networks linking sensors, weapons, intelligence, and military units; have again transformed the continental-maritime balance. South Korea is currently experiencing this transformation through the diplomatic push and pull between China and the U.S. as they seek to settle the continental-maritime balance. Over the next five years, the convergence of contest, miscalculation, and uncertainty will come to the fore. The intermittent boil-overs will potentially become more frequent, and the the stability lid less secure. *** Help a very thirsty academic - [Buy Me a Coffee](https://buymeacoffee.com/junotane)! ## Related articles - [[2026-10-22 Tracing ideas on North Korea|Tracing ideas on North Korea]] - [[2025-06-03 South Korea’s strategic futures between continental and maritime powers|South Korea’s strategic futures between continental and maritime powers]] - [[2026-04-06 Contesting the rimlands - Ukraine, Iran, Korea?|Prediction markets and North Korea]]
