Today's episode is about minerals, specifically rare earth elements that quietly power our modern world, from electric vehicles to missile guidance systems. These 17 obscure materials are the backbone of our 21st century technologies, and right now they're overwhelmingly controlled by a single country, China. We'll break down what rare earths are, why they matter, how China came to dominate the global supply chain and what the US can realistically do to catch up. We'll also talk about America's vulnerabilities and what needs to change if we are to reclaim our industrial and strategic independence.
