During WWII there was a saying, something like "Careless talk, costs lives" it refereed to the fact that every day conversations can be overheard, and if you talk about something sensitive, you don't know if the enemy spies are close by.
Perhaps the reason the military elite are not able to speak up, is fear, fear of talking to someone who will turn them in. In turn, those who are more loyal and likely to do that, are fearful if they don't they will end up dead too.
