Trump threatened tariffs Monday to bring semiconductor, chip and pharmaceutical production back to the US, arguing that many companies have relocated to Taiwan. “They left us and went to Taiwan, which is about 90% of the chip business, and we want them to come back,” said Trump.

Today, most of the world's semiconductor manufacturing comes from TSMC, which has spent years expanding its operations in Taiwan as a hedge against Chinese aggression. The world needs TSMC, which helps to keep the CCP's "one China" rhetoric just that—rhetoric.
