This is what happens
This is what happens when you buy a weapons system to counter a threat that doesn't exist, and probably never will. In something like an actual shooting war for national survival like those in the first half of the 20th century arms manufacturers had plenty of incentive to produce stuff that worked. Sure, they sometimes (often) got it wrong through incompetence, but rarely as the result of intentional fraud. With the new century the West is well past that and the military-industrial complex is coming up on almost a half century of profiteering off of unrealized fears and fawning politicians.
