I don't think this is a fair representation of what happened. US capacity existed and some additional came online, but then largely failed because of overseas product still coming in below their cost. Semiconductors after a shooting war with China would be a different picture: an imminent return to normalcy wouldn't be in everyone's economic calculations.

Not even a single part? Now you're in hyperbole-land.

No, but they actually tried really hard. Dozens of companies were recruited for the effort, and they just gave up after realising that they can't even get a single part in the blowing machine to be made in the US.
