Taiwan's TSMC produces more than 90% of the world’s leading-edge semiconductors. 🇹🇼 🇨🇳 If China seizes Taiwan, the consequences would be severe. Beijing would gain control of TSMC. It would breach the US-led First Island Chain, breaking seven decades of American naval containment in the Western Pacific. It would also give Chinese submarines unobstructed access to the deep Pacific Ocean. Japan, South Korea, and the Philippines would face a hostile power at their doorstep. Beijing would gain command of the shipping lanes carrying one-third of global trade.
