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.

The Taiwan Semiconductor Manufacturing Company produces the majority of the world’s most advanced logic chips. Its fabs in Hsinchu and Tainan manufacture the processors that go into every iPhone, every data center GPU, every advanced weapons guidance system, and most of the AI training infrastructure that has been built in the past three years. No other company operates at the frontier process nodes at anything close to TSMC’s volume. No other geography concentrates this much irreplaceable productive capacity in a single location. The decision by the global electronics industry to concentrate its most advanced semiconductor production on an island that a nuclear-armed neighbor claims as its own territory is the most significant strategic miscalculation of the early twenty-first century, and it has not been corrected.
