The U.S. and Taiwanese Militaries Can’t Really Fight Together

Why It Matters

Without seamless coordination, U.S. and Taiwanese forces could fail to present a credible deterrent to China, increasing the risk of a successful invasion. Strengthening interoperability directly ties to regional stability and U.S. strategic interests in the Indo‑Pacific.

Key Takeaways

• Taiwan aims for 5% of GDP defense spending by 2030
• U.S. arms sales to Taiwan total $14 billion, now on hold
• Lack of joint command systems creates real‑time coordination gaps
• Congress passed Taiwan Enhanced Resilience Act to fund training
• Interoperability gaps risk undermining deterrence against China

Pulse Analysis

The strategic ambiguity that has defined U.S. policy toward Taiwan masks a more concrete problem: the two militaries cannot operate as a single force. Unlike the deeply integrated U.S.–Japan and U.S.–South Korea alliances, Washington and Taipei lack shared command‑and‑control architecture, joint doctrine, and regular combined‑exercise cycles. This deficiency means that, in a crisis, commanders on either side would be looking at divergent operational pictures, slowing decision‑making and increasing the chance of missteps.

Technical integration is only half the battle. To fuse Taiwanese radar and coastal‑defense data with U.S. Aegis and missile‑defence networks requires compatible IT systems, standardized data formats, and agreed engagement rules—investments that are costly and politically sensitive. Equally vital are process integrations: regular staff‑planning workshops, officer‑to‑officer exchanges, and expanded participation in the International Military Education and Training (IMET) program. These measures build the trust and shared mental models that turn hardware compatibility into effective combined‑arms action.

Congress recognized the urgency with the Taiwan Enhanced Resilience Act, authorizing expanded training and exchange programs. Yet bureaucratic inertia and diplomatic caution have slowed execution. For deterrence to remain credible, Washington must prioritize funding, streamline approvals, and elevate Taiwan’s integration into U.S. network‑centric operations to the level enjoyed by other allies. Doing so would signal to Beijing that any aggression would meet a unified, technologically synchronized response, reinforcing stability across the Indo‑Pacific.
