The question is, whether they were covering it up a real problem there, or they just wanted to avoid some idiot higher-up completely overblowing the importance of a single incident. I can somewhat understand their thinking if the latter was the case, given that overblowing stuff way beyond their importance is what politicians do as a part of their jobs.
Exactly - the point of a nuclear deterrant is to be credible, but never used. In a situation you need to launch, whether all the missiles work properly is irrelevant - you just need the majority of them to be assured to.
