The scenario that receives the least public attention in Taiwan Strait analysis is probably the most likely path by which Beijing would attempt to compel Taiwanese political capitulation: a maritime blockade that cuts off Taiwan’s trade without the military and political costs of a full amphibious invasion. Taiwan is an island. It imports approximately 98 percent of its energy and a significant portion of its food. Its export-oriented economy depends entirely on maritime access. A blockade that prevented ships from reaching Taiwanese ports would, within weeks, begin to produce economic and social conditions that make governance difficult and, within months, conditions that make it impossible. The strategic logic is coherent, the military execution is feasible, and the allied response problem is severe.

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.
