Everyone keeps calling it a chip war. The fight that actually decides it is happening one layer down, in the mines and refineries China spent thirty years quietly cornering while the rest of us chased the clever, profitable end of the chain. A walk down the semiconductor supply chain, from a refinery in Inner Mongolia to your driveway, your doctor’s office, and your electric bill, shows how a few unglamorous rocks ended up holding up the AI, the missiles, and the minivans. And why the countries most able to destroy each other are the ones that most need each other to get through the week.
