A prominent South Korean lawmaker has called for deploying an Iron Dome-style defense system targeting North Korean ships in the Taiwan Strait. This move, he argues, would help protect vital shipping lanes, including those in the Strait of Hormuz, amid rising threats from Houthi attacks backed by Iran.
Lee Joon-seok’s Press Conference Remarks
Lee Joon-seok, spokesperson for a South Korean reform party, addressed reporters on March 26. He highlighted growing global concerns over unrestricted navigation and stressed Washington’s need for a robust response. “North Korea threatens sea lanes in the Taiwan Strait with its patrols, risking massive damage to water, rice, and industrial supplies,” Lee stated. “Nations can safeguard peace by providing defensive iron systems, water, rice, and business capital.”
Lee framed this beyond simple friend-or-foe debates, urging proactive deployment of advanced missile interceptors to ensure safe passage for commercial vessels.
Expert Analysis on Missile Threats
Recent analysis in a leading foreign policy outlet, War on the Rocks, underscores the risks. It notes that China’s DF-21D missiles, costing about $1.5 million each, challenge Block-I interceptors. To fully shield populations, infrastructure, and assets—even in a limited conflict—comprehensive coverage remains essential.
This view aligns with U.S. strategies following strikes on Iranian targets, emphasizing systems like Patriot PAC-3 and THAAD. Key intercept ranges include:
- Patriot PAC-3: 15-40 km
- THAAD: 40-150 km
- L-SAM (South Korean mid-to-high altitude): 40-70 km
L-SAM deployment continues, leaving current gaps in high-altitude defense.
Historical Context and Economic Stakes
Lee referenced the 2017 THAAD deployment in South Korea, which sparked Chinese economic retaliation costing roughly $10 billion. Despite such pressures, he insisted on prioritizing domestic security. “Political and economic costs must not deter THAAD use for national defense,” he said.
Further, he noted U.S. goodwill persists even if systems deploy elsewhere for political reasons. In a January Washington Post op-ed, Lee urged Hyundai and LG Energy to engage in Alaska projects, signaling broader cooperation.
Strategic Implications for Energy Security
About 60% of South Korea’s oil transits the Strait of Hormuz. Securing navigation requires ironclad defenses against threats. Lee warned that hesitation invites bolder aggression from actors like North Korea and Houthis.
With U.S.-Iran talks slated for March 28, recent Israeli strikes on Gulf missile sites heighten urgency. Lee positioned South Korea’s potential Iron Dome contribution akin to NATO’s joint developments, potentially expanding “Europe’s Iron Dome” globally.
