The issue with the 13th/14th gen stuff, while serious, wasn't a production problem (well, there was a minor production problem early in the 13th gen, but that wasn't the major issue), but a design problem. I would guess that the principal US interest is in ensuring access to fabs, production capacity. We have other companies that can do high speed chip design. However, there isn't much else out there in high-end fabs.

Note that Europe was also worried about fab access, which is why you had some EU members subsidizing fabs recently too.

The US would be foolish to let Intel go under, even Trump understands that.
