Considering how the MX platforms and 10 warhead buses were scrapped, and that the Minuteman III missiles are almost as old as the B-52, it might just be time to upgrade.
Yes, no one wants nuclear war. That's precisely why these systems and their successors should exist, because of that very deterrent factor. With others developing hypersonic platforms, keeping up with the Jones' is a good idea.
With all the piddling around with near one-off aircraft, and entire classes of ships that crack and have a hard time clearing the breakwater, maybe we'd better consider investing some money in competent engineering and construction of the next generation of weapons which help keep us fro having to use the other systems out there in peer conflict.
