President Lee Jae-myung Nuclear Submarines: Seoul’s Strategic Pivot to Armed Pragmatism

Shaking hands while sharpening the sword. On January 19, 2026, South Korean President Lee Jae-myung met Italian Prime Minister Giorgia Meloni in a summit that signals a massive shift in Seoul's foreign policy. While Lee entered office with a vision for "pragmatic peace," the grim reality of global geopolitics is forcing a much harder line.

President Lee Jae-myung Nuclear Submarines: A Pursuit of Plan B

Since assuming office in June 2025, Lee has seen his peace initiatives stalled by the deepening alliance between Kim Jong Un and Vladimir Putin. With Russia suspected of providing critical telemetry and re-entry technology for North Korea's ICBM program, the traditional leverage of economic aid has become largely irrelevant.

In response, the Lee administration has prioritized the official pursuit of nuclear-powered submarines. Having secured approval from U.S. President Donald Trump during their October 2025 summit, these assets represent a permanent undersea deterrent capable of tracking Pyongyang’s missile-carrying submarines.

Global Defense Power and the European Strategy

Seoul isn't just arming itself; it's aiming for the ranks of the top five military powers globally. By doubling down on K-defense exports and AI-driven combat systems, South Korea is transforming into a global arms powerhouse. This military buildup provides the leverage necessary for Lee’s new diplomatic maneuver: the "European route."

Recognizing that China and Russia are unlikely to abandon Pyongyang, Lee is seeking a multilateral framework with democratic powers like France, Germany, and the United Kingdom. The goal is to frame North Korean security issues as a holistic international agenda, reducing reliance on bilateral ties and increasing South Korea's influence as a middle power.
