Context
The Columbia-class submarine is built to be the ghost-quiet future of American naval power. But as Ryan Musto points out in this piece from 25 June 2026, the magnets that make the boat move and stay silent rely almost entirely on rare earth metals refined in China. The essay skips past the usual alarm bells about supply chains to ask a harder, more practical question. If Beijing can simply crash mineral prices the moment an American competitor tries to open a processing plant, how exactly does the Pentagon convince private investors to build one anyway?
