I would say yes. Speculation follows: If the unthinkable happens, and assuming it devolves into a cold rather than a hot war (eg the Trump administration decide not to send soldiers and weapons to Taiwan but let the Chinese have the island), then US TSMC is appropriated, Intel or AMD or Qualcomm are told to run it, and all three are instructed to ramp up manufacturing capacity as aggressively as possible. If it's more like the status quo saber rattling, then I think USG would still want a 100% domestic supplier to be acting as a second source for the local economy and a primary source for anything the defense-industrial complex needs.
