TSMC controls 60% of global semiconductor production, not "90%+." If your argument is: "well, they control the advanced nodes!!" - if Taiwan is attacked, the things you're using these advanced chips for will no longer be relevant.
Missiles and radar powered by Intel/Altera chips will do the job just fine until more domestic fab capacity can be spun up. Most defense products are running on processes from two decades or more ago and are already legally forced to consider adversarial supply chain issues.
