the only thing i would expect enough disloyalty among middle/upper leadership to consider command failure would be active military deployment inside the US. and not like reserves/national guard stuff like we’ve seen. that would probably require a sudden and decisive purge.

short of that, maybe if they wanted to premeptively nuke another nuclear power, there might be a confab ahead of time to find out who in the chain might hesitate to be a warrior for christ and murder a billion people because some drunk radio shock jock woke up with a hangover.
