How a Battery Shortage Could Threaten US National Security

Eugene Gholz, a Notre Dame political science professor who previously advised the Pentagon, said national security concerns over energy have been exaggerated before, like with oil. He believes that's happening again. Gholz thinks the national security risk of electric vehicle adoption are small, and less than the oil supply chain. "F-35s won't fall out of the sky because we don't have access to cobalt imports," Gholz told CNN Business. "It's not like you need to constantly deliver diesel to the forward operating base. Once the base has a battery, it's got a battery for years."
