Nope. CINC. All it takes. Personnel reliability is a big issue and one can assume not every command will be carried out and if the refusal to obey is high enough up significant portions could fail. If “the one” refuses then nothing happens. She won’t ever know the codes. Were I the officer with the football I would refuse her. Destroy the world to satisfy some psychotic delusion of a criminally corrupt politician? Sorry, don’t think so.
So “personnel reliability” has another parameter that the planners fail to attend to an, in fact, cannot address. Even an ironclad chain of the most dedicated officers may fail simply because they do not trust the commander, the weakest link in the chain. No one will ever trust Hillary. No one.
This does not make us safer. In fact it makes things much less safe.
Wait... you mean if she gets elected and has a bad day (emails, etc), she could launch just because???
