Beyond Standby Forces: Lessons for Tokyo and Seoul

The NATO Response Force and EU Battlegroups long suffered from a fundamental flaw: they were rotational structures requiring political consensus at the moment of crisis. This design failed to account for the reality that governments often hesitate to commit high-readiness units when faced with competing national priorities. In contrast, the German-Dutch approach internalized cooperation within permanent command structures. By integrating entire brigades and embedding personnel down to the battalion level—such as Dutch soldiers operating German Leopard 2A6MA2 tanks—the two nations moved beyond temporary interoperability to a state of routine organizational synergy.

Japan and South Korea, lacking a formal mutual defense pact, cannot replicate this NATO-style integration. However, they can adopt a functional approach to operational preparedness. Establishing a standing bilateral adjustment mechanism between the Japanese Joint Operations Command and South Korean headquarters would allow for intelligence exchange and logistics coordination without requiring a full alliance. By creating small-scale cells focused on missile warning, maritime domain awareness, and cyber defense, both nations could streamline their responses to regional escalation.

Crucially, exercise design must move away from the assumption of unlimited US support. Planners in Tokyo and Seoul should prioritize scenarios where American assets are already stretched thin. By institutionalizing reciprocal logistics, base support, and target allocation for North Korean threats, both countries can enhance their independent and bilateral capabilities. This functional integration provides a pragmatic path toward security, ensuring that when the decision to act is finally made, the technical and operational frameworks are already in place to execute it.
