South Korea

The latest US National Security Strategy (NSS) marks a significant shift in Washington’s approach to the Korean Peninsula by excluding North Korean denuclearization as a central concern and redirecting deterrence responsibilities primarily onto allies, especially South Korea. This shift reflects a reprioritization in US strategy that reduces direct engagement and increases South Korea’s burden in managing North Korea, resulting in a more volatile and unpredictable security environment.

North Korea views this strategic retrenchment as an opportunity to strengthen its position by adopting a more confrontational stance toward South Korea, potentially codifying a hostile inter-Korean doctrine at its upcoming Ninth Party Congress. Its military provocations serve a dual purpose: challenging South Korea’s control over contested maritime and air defense zones in a calculated manner to avoid large-scale escalation, and provoking political divisions within South Korea related to responses and the credibility of US extended deterrence.

South Korea is responding to these provocations by significantly increasing its defense budget and investing in advanced military capabilities, signaling a shift toward greater self-reliance and reduced dependence on the US nuclear umbrella. Discussions on indigenous nuclear options and strategic assets have entered mainstream political debate, reflecting growing doubts about the reliability of US deterrence.

The absence of North Korea from the US NSS increases the risk of an accelerated arms race on the Peninsula, compounded by US global strategic actions that raise perceptions of unpredictability and willingness to use force. This dynamic incentivizes both Pyongyang and Seoul to engage in competitive military buildup and riskier postures, especially around sensitive zones like the Northern Limit Line and Korea Air Defense Identification Zone, with a heightened chance of destabilizing escalation.

Underlying this situation are flawed assumptions within US policy that ambiguity and burden-shifting will maintain stability. Without clear communication, senior-level coordination, and explicit crisis management policies—including well-defined red lines—burden-shifting encourages risk-taking by all parties. The evolving arms competition and alliance asymmetries on the Peninsula increase the likelihood of costly miscalculations and military adventurism unless strategic signaling and allied coordination improve significantly.

Yonhap | English | News | Jan. 23, 2026 | North Korea

A joint team of police and military investigators in South Korea raided the homes and offices of three civilian suspects suspected of flying drones into North Korea, in violation of the Aviation Safety Act. The searches began at 8 a.m. on January 21, 2026, as part of an ongoing investigation into drone incursions reported by North Korea in September 2025 and January 4, 2026. South Korea's military denies involvement, stating it does not operate the drone models in question.

One suspect, a graduate student surnamed Oh in his 30s, publicly admitted to flying the drones in a media interview last Friday. He and another suspect, both alumni of the same Seoul university, previously worked at the presidential office under former President Yoon Suk Yeol and co-founded a drone manufacturing startup in 2024 with university support. Oh also operated two online news outlets focused on North Korea, which were shut down amid accusations that they served as fronts for military intelligence operations.

During the raid, investigators searched the university-based startup but did not search the news outlets' offices. The investigation remains ongoing, with authorities keeping all possibilities open. Meanwhile, North Korea claims to have forced one of the drones to fall using electronic means near its border city of Kaesong in late September 2025, escalating tensions between the two countries.

SKT 'A.X K1', 옴니모달로 진화…“소버린 AI 마중물 될 것”

SK Telecom's ultra-large AI model, A.Dot X (A.X) K1, is advancing into an omnimodal model as part of the second phase of its independent AI foundation model project. This upgrade will enable the model to understand and process speech in real time alongside text and images, aiming to establish leadership in sovereign AI. The A.X K1, already a model with approximately 500 billion parameters, will sequentially incorporate multimodal functions, including voice and image recognition.

Professor Kim Geon-hee of Seoul National University highlighted the transition from multimodal models, which integrate text, photos, and videos, to omnimodal models that also include speech understanding. He emphasized the technical difficulty of implementing real-time voice conversations due to their bidirectional and simultaneous nature, requiring the model to handle interruptions, brief feedback, and emotional nuances. Past approaches using separate speech-to-text and text-to-speech systems faced delays and lost key information, such as breathing and emotional signals.

To address these challenges, recent developments focus on integrated language models capable of processing voice information directly. The core strategy involves fine-tuning a powerful pretrained language model using diverse data, including voice, to achieve comprehensive omnimodal capabilities. SK Telecom aims to deploy these advancements across various services like A.Dot, T map, and B tv, and expects the technology to play a central role in enhancing AI applications in gaming and mobility through partners Krafton and 42dot.

Professor Kim stressed that the success of sovereign AI depends heavily on effective use of national core data sovereignty, which includes largely unstructured data in multiple formats. An omnimodal model allows for direct training and operation of such data without relying on external platforms, thus reinforcing both digital sovereignty and sovereignty over physical infrastructure.
