So to put it simply; the US wants to be sure it can still make H100's even if the rest of the world goes to shit.
I don't think that is quite right. It is a very important ability. I don't think it is the "most important" ability. If you have semiconductor fabs but not dry docks to build capital ships you will be in for a world of hurt. If you have semiconductor fabs but not agriculture to feed your people you will be in a world of hurt. If you have semiconductor fabs but not the ability to cast solid-fuelled rocket engines for your missiles you will be in a world of hurt.
It is one of the many important abilities. The reason we are talking about it is not because it is the "most important", but because it is at danger of being lost. We don't talk about the other equally very important abilities (like dry docks for giant ships, agriculture to feed the nation, or solid fuel casting, or a myriad of other things) because nobody worries about those going away.
Carriers are still very important to US force projection and hypersonic missiles are really overblown. We also seem to be readily able to take out existing hypersonic ballistics.
Also a 5 year war with the US and China that starts with a multiple thousands of missles? That’s just going to be a nuclear exchange and last not very long at all if one sides detects any launch like that.
I'd be surprised if they don't use some ASBMs.
But larger ships are built to take an incredible amount of punishment. It typically takes a heavyweight torpedo to crack them (hence why ASW is a primary skill set for navies). The physics of getting a 1/4 ton+ non-nuclear warhead (torpedo class) highly maneuvering are rough.
And there's a reason the Navy developed and deployed SM-6, and is now adding SEWIP Block III...
Did they make mistakes?
Loading their capital ships decks with exposed, extremely large anti-ship missiles?
And they likely still would have been able to tow it back to port, if the weather hasn't been bad.
What about all of those submerged ships that will lay waste to their opponent with the weapons they carry?
The US certainly has that capability - should food supply ever become critical, slaughter cattle, pigs and sheep and redirect the grains used to feed them to the population. The amount of grains would feed 800 million people [1].

Very modern chips are more suited for intelligence work no weapons systems per se. The physics of flight, artillery and balistic missiles is pretty much well understood, we don't need machine learning for that. Some modern systems use computer vision as a terminal guidance system, but again, you don't need state of art semis for that.
Stuff like this wasn't realistic from systems made in the 90s or even 00's.
Add in the fact of the black box nature of ML, and it becomes a pain to anything that requires a certification.
Also nuclear weapons simulation is what keeps the DoE continuously buying new world leading super computers.
