Defense Supply Chains Face Competition From Tech Sector

Retired U.S. Navy Commander Phil Ehr warns that copper is moving beyond its traditional role as an industrial metal to become a national security concern. With defense systems, AI infrastructure, the power grid, and consumer technology all competing for the same supply chain, Ehr notes that copper is essential to modern electrical economies and weapons systems. He emphasizes that if supply tightens, defense needs are likely to take priority, potentially impacting the grid and consumer demand. This was reported by Kitco News.
