Yeah I think everyone understood that analogy you spelled out w/respect to MAD.

China would not engage in nuclear escalation in response to the US striking Taiwan, and China does not otherwise possess the ability to strike the US homeland without incurring a nuclear response, so there is no mutually assured destruction with regards to semiconductor industry. In this hypothetical, the US would succeed in striking Taiwan and China would not escalate into nuclear war. But, the US would not strike Taiwan. Taiwan would destroy their own industry before that happened.
