The US has plenty of any conceivable war. There is probably long time to restart production since haven’t done it in a while. The big factor is that the deployment platforms are limited. There are 400 Minuteman III missiles sitting in silos. They could put more warheads on them, but those are sitting in storage. The same is true of Trident missiles on submarines. They could make nuclear gravity bombs but those aren’t really useful. We also have lots of those in storage.
