European governments have spent the past four years discovering that their economic exposure to Taiwan is larger and more structurally significant than their political frameworks were designed to address. The semiconductor dependency is the most acute dimension: European automotive manufacturers, industrial equipment producers, telecommunications companies, and defense systems contractors all depend on Taiwanese chip production for components that have no short-term European substitute. A Taiwan Strait conflict that disrupted semiconductor supply would hit European industry within weeks and would affect European defense procurement on timescales that matter for the continent’s own security.
