Episode 94 – Trump’s Rare Earth Ultimatum: What the China Warning Means for U.S. Security and Supply Chains

In this episode of The Deep Dive, we examine the strategic and economic confrontation now unfolding between the United States and China over rare earth elements, the 17 metallic elements that underpin modern defense systems, advanced electronics, and clean energy technologies.

Drawing from National Defense Lab’s white paper, they trace how China gained control of more than 80 percent of the world’s refining capacity through deliberate industrial policy and how that dominance became an instrument of statecraft. The discussion explains why rare earths are no longer just commodities but strategic assets, and how the U.S. is moving to rebuild resilience through domestic production, allied partnerships, and AI-driven material innovation.

Key Topics:

• Why rare earth elements matter and where they are used
• How China achieved global dominance in refining and manufacturing
• The vulnerabilities this creates for U.S. defense systems and energy transition technologies
• The history of U.S. disinvestment and environmental constraints that ceded control
• The 2010 and 2023 export control shocks and their global ripple effects
• U.S. pathways to resilience: domestic expansion, allied cooperation, technological substitution, and recycling
• Integration with the FY2027 R&D Budget Priorities on energy, materials, and AI innovation
• The environmental and diplomatic trade-offs of rebuilding refining capacity at home
• The broader question of balancing security, economics, and sustainability in national strategy
