Alternatively, Beijing may seek to negotiate with or coerce Taipei (or both) in order to allow China sole access to TSMC and block chip exports to the United States, thereby securing China’s own supply while crippling American industry.

But earlier in the article it's mentioned that the US effectively has a "kill switch" on TSMC (by cutting off key supplies needed to fabricate semiconductors). If this is true, then the scenario presented by Blanks seems unlikely -- or am I missing some detail?
