Highlights

• A simulated scenario demonstrates how a Chinese rare earth export ban could systematically degrade U.S. military readiness over a 10-year period.
• Over 95% of U.S. defense systems have critical rare earth dependencies, creating a potential vulnerability in military infrastructure.
• The study warns of a potential 8-12 year military-industrial lag that could fundamentally reshape global strategic power dynamics.

A provocative new war-gaming study led by Wei Meng (opens in a new tab) of Dhurakij Pundit University (Thailand) and the University of Western Australia outlines a simulated scenario in which a total rare earth export ban from China to the United States results in the structural degradation of U.S. military readiness and defense-industrial capacity over a 10-year period.

Published as a sandbox simulation model, the study presents what Meng calls a “non-kinetic strategic deterrence” framework. It simulates a four-layer chain reaction (1) policy input (2) resource disconnection (3) system degradation, and (4)warfighting capability lag—based on China enforcing a zero-tolerance export ban on key rare earths and critical technology licenses.

Key Findings: Timeline of Strategic Degradation

Using graph neural networks and LSTM time-series models, Meng’s team forecasts the following timeline:

• Years 1–3: Operational degradation begins. Stockpiles of rare earth-intensive systems like the F-35 and Virginia-class submarines dwindle, impacting readiness.
• Years 4–6: A “strategic capability gap” emerges as U.S. platforms stall while China accelerates deployment of sixth-generation fighters, hypersonic weapons, and AI systems.
• Years 7–10: U.S. defense systems enter systemic lag. China achieves structural dominance through what the study calls a “three-dimensional suppression strategy.”

The economic impact is estimated at $35–40 billion annually, totaling $3.5–4 trillion in lost capacity over a decade. AI platforms alone could incur over $ 100 billion in losses due to gallium and germanium supply cuts.

Military Dependency Risk

According to the study’s vulnerability matrix, over 95% of U.S. defense systems—including radar, optics, targeting systems, and propulsion—trace their rare earth dependencies back to China. Example metrics:

• F-35: ~418 kg of rare earths per unit, complete supply failure halts production.
• Virginia-class subs: ~4,173 kg per unit; propulsion and stealth systems critically exposed.
• AI warfare platforms: Reliant on Chinese gallium/germanium; chip-level disruption leads to rapid degradation.

The study refers to this as a “domino logic failure”—where a single resource chokepoint leads to cascading platform breakdowns and functional paralysis.

Strategic Insights and Implications

The paper argues that rare earths have graduated from economic inputs to instruments of systemic deterrence. It proposes export controls, technology embargoes, and a blacklist mechanism as tools for China to weaponize supply chains—achieving strategic goals without direct conflict.

Key Implications

• Generation Gap Formation: The U.S. could face an irreversible military-industrial lag of 8–12 years if the current dependency isn’t addressed.
• Irreplaceability of Capacity: Even with investment, U.S. refining and alloying capability rebuilds are projected to take 5–10 years at a cost exceeding $100 billion.
• Risk of Systemic Disablement: The report warns that rare earth supply cuts do not just “hurt”—they “break” the deployment and sustainment logic of U.S. warfighting assets.

Limitations

The simulation does not model:

• Potential U.S. or allied countermeasures (e.g., stockpiling, mining expansions, allied imports);
• Intelligence, diplomacy, or geopolitical backlash;
• Supply chain substitutions (e.g., via Canada or Australia) under emergency timelines.

However, its structured, AI-enhanced modeling framework offers a realistic baseline for assessing strategic risk and resilience planning.

Conclusion

For Rare Earth Exchanges (REEx) readers—especially defense planners, policymakers, mining executives, and financiers—this study is a call to recalibrate the valuation of rare earths. The simulation reveals how resource asymmetry can act as a time-delayed strategic weapon, reshaping global power without a single missile fired.

Investors and governments should take note: the battlefield of tomorrow may be determined by today’s refining capacity.
