Same problem, just worse. If America can't source butt-cheap STM-32s then our efforts at assembling boards might as well go up in smoke. But that's easy enough... just bootstrap domestic refineries for every precursor, purchase a few billion dollars worth of ASML products, hire and train a few thousand workers while you build a dozen-odd factories, convince Texas Instruments to license ARM hardware officially at-cost and design an American-made core, validate and sample the new chip to your assemblers and pass the research/development costs onto the consumer with every device!

That's the problematic bit. Now you have an officially-licensed and tested STM-32 core that can serve as a drop-in replacement at 10,000% of the cost of an identical Chinese bootleg model. Part of the problem is that the US has to pay for ARM licenses that China refuses to acknowledge, but another part of the problem is that our supply chain's just not built to compete. We're a digital import-state.

So it's about time to reverse some of that.
