Kim Jong-un Claims North Korea's Missile Tests Strengthen Nuclear Deterrent

NextFin News - North Korean leader Kim Jong-un oversaw a strategic test of a large-caliber multiple rocket launcher system on Tuesday, January 27, 2026, asserting that the successful launch has fundamentally strengthened the country’s "nuclear war deterrent." According to the state-run Korean Central News Agency (KCNA), the system demonstrated enhanced precision and mobility, with four rockets successfully striking a maritime target approximately 358 kilometers from the launch site. The test, which was monitored by defense authorities in Seoul and Tokyo, involved projectiles that fell into the East Sea outside of Japan’s Exclusive Economic Zone.

The timing of the launch is particularly significant, coinciding with a period of intense diplomatic and economic friction in Northeast Asia. While Kim praised the technical superiority of the weapon—claiming no other nation would be able to match such technology in the coming years—the test occurred just as U.S. President Trump announced a return to 25% tariffs on South Korean exports, citing Seoul's alleged failure to implement a multi-billion dollar investment deal. This convergence of military provocation from the North and economic pressure from the United States has placed the administration of South Korean leader Lee Jae Myung in a precarious strategic position.

From an analytical perspective, Kim’s latest rhetoric signals a transition from mere survival-based deterrence to a more assertive "tactical nuclear" doctrine. By focusing on large-caliber multiple rocket launchers, Pyongyang is refining its ability to saturate regional missile defenses. These systems are designed to deliver tactical nuclear warheads over short distances, specifically targeting South Korean ports, airfields, and U.S. military installations. The emphasis on "overcoming interference" and "mobility" suggests that North Korea has successfully integrated lessons from modern electronic warfare, likely aided by its deepening military cooperation with Russia following the 2024 mutual defense pact.

The geopolitical impact of these tests is amplified by the current "America First" posture of the U.S. administration. U.S. President Trump has recently signaled a desire to reduce direct U.S. involvement in South Korean defense, pushing for what his administration calls "strategic self-reliance" for allies. According to The New York Times, this shift has created a perceived security vacuum that Kim is eager to exploit. By demonstrating a robust and modernized nuclear delivery system, North Korea aims to convince both Washington and Seoul that the cost of military confrontation is prohibitively high, thereby forcing a de facto acceptance of its nuclear status.

Furthermore, the internal political discord in South Korea provides a fertile ground for North Korean influence. The bickering between Lee’s Democratic Party and the opposition People Power Party over trade ratifications and defense spending has slowed Seoul’s response to both the Northern threat and the American tariff pressure. Kim’s promise to soon unveil the "next stage" of his nuclear program suggests that the regime is moving toward the mass production and deployment of these tactical systems, rather than using them as mere bargaining chips for sanctions relief.

Looking forward, the trend points toward a permanent "nuclear-armed peace" on the peninsula, where North Korea continues to modernize its arsenal while the U.S.-South Korea alliance undergoes a fundamental restructuring. As U.S. President Trump continues to use economic tools like tariffs as primary levers of foreign policy, traditional security guarantees are being re-evaluated. For Pyongyang, the goal is no longer just to deter an invasion, but to decouple the alliance by proving that the U.S. nuclear umbrella is either technically penetrable or politically unreliable. The international community must now contend with a North Korea that views its nuclear capability not as a temporary shield, but as the permanent axis of its national identity and regional leverage.
