Doesn’t matter, there’s nothing an individual can do to compromise one.

As much as I respect your experience, if there are enough of them in the military, there can be more than one with 'hands on the trigger.' I somehow doubt that all nukes once armed can be remotely disarmed. Further, if the Jihadis can take over subsonic passenger planes and fly them into buildings hundreds of miles away before they are shot down, how could you be so confident we can rely to such degree upon procedure?
I had a boss once who was retired USAF SAC.
He figured out how to launch multiple missiles and bypass the safeties when he was in a MX unit.
After he alerted the USAF, they fixed the system.
