Even as Donald Trump claimed Iran’s navy was “obliterated,” analysts warn a new threat is emerging in the Strait of Hormuz. Iran’s IRGC has deployed a “mosquito fleet” of small, fast attack boats, drones, and coastal missiles that are cheap, agile, and hard to detect. These units have already disrupted shipping lanes, slowing global trade and raising insurance costs. Experts say Iran does not need to fully block Hormuz to exert pressure—just make it dangerous enough. With one-fifth of global oil flowing through the strait, even minor disruptions carry massive global consequences.
