Rare earths aren't actually rare. That's the detail that gets lost every time the phrase shows up in a headline. They're moderately common elements, present in ore bodies on every continent — what's scarce isn't the material, it's the willingness to do the dirty, expensive, environmentally punishing work of separating and refining it into something usable. China made that decision deliberately, starting not long after Deng's 1992 remark that this series opened on, and thirty years of consistent follow-through is why the country now controls somewhere between 90 and 92 percent of global rare earth refining capacity, and roughly 90 percent of the magnet manufacturing that turns refined material into something an F-35 or an electric motor can actually use.
The 1,000-Ton Answer
America has exactly one significant rare earth mining and processing operation: MP Materials, at the Mountain Pass mine in California. It is not a small effort — the company has a multibillion-dollar partnership with the Pentagon, a magnet-manufacturing alliance with General Motors, and a new facility in Fort Worth built specifically to close the gap this chapter is about. That facility's production target is 1,000 tons of magnets a year. China currently manufactures more than 300,000 tons annually. The American effort isn't nothing — it's the first serious domestic attempt in decades — but the scale gap between a 1,000-ton target and a 300,000-ton baseline says more about three decades of insulation than any policy announcement can undo in a news cycle.
The Rationing Has Already Started
This isn't a hypothetical vulnerability being discussed in a think tank. It's actively happening. Yttrium exports to the United States fell from more than 66 tons in a single month in early 2025 to just 20 tons by February 2026 — a drop concrete enough that aerospace manufacturers, who use the material as a thermal coating on jet engines, have publicly said they're rationing supply and could face production pauses if volumes don't recover. In June 2026, China blacklisted MP Materials and USA Rare Earth from its own market entirely, a retaliatory move that analysts mostly read as symbolic, since neither company sold much into China to begin with — but symbolic moves in a live supply chain still land as warnings.
The response has started to look coordinated rather than purely domestic: a G7 agreement reached in Paris set a target of capping any single country's share of rare earth imports at under 60 percent by 2030. That's a real acknowledgment of the problem, and a real deadline. It's also four years away, in an industry where the current dominant supplier has had thirty.
Not a Shortage — A Choice, Compounding
Here is the cleanest version of this series' entire argument, distilled into one material. There is no scarcity of rare earths in the ground. There is a scarcity of refining capacity, and an even deeper scarcity of magnet manufacturing capacity, and both of those scarcities were manufactured — not by an enemy sabotaging American industry, but by three decades of American companies and policymakers deciding it was cheaper to let someone else do the dirty, capital-intensive work. China didn't steal this chokepoint. It built it, patiently, while the alternative wasn't building anything.
Rare earth refining isn't beyond American capability in any physical sense — it's beyond American willingness, and has been since before most of the workers at Mountain Pass were born.
Every material in this series tells some version of the same story, but minerals tell it with the least ambiguity. Ships have a monopoly yard because building carriers is genuinely hard. Chips have a capability gap because leading-edge fabrication is genuinely difficult. Rare earth refining isn't beyond American capability in any physical sense — it's a choice, compounded over thirty years.
Five materials. One fork. Same insulation, wearing five different uniforms. The next chapter puts them all on the same page.
