But if POTUS says at 5pm DC time, No military action, no cross border, and then he becomes unavailable, then his last standing order stands until he changes it. So if he went to bed, for example, nobody could change his standing orders.
I imagine that a lot of extreme military, CIA and State Dept. craziness was going down while Obama was sleeping. Aircraft must be told proceed, or return to base, or they fall from the sky. I imagine many HEATED arguments around the globe on phone, text and email, subject, Well wake the damn president up! Followed by, I cant! You MUST stand down the mission!
Kind of reminds me of D-Day no one was to wake the Fuhrer. Even though the Armor was needed in Normandy. Funny how two dictators both have people acting the same way when their is a emergency and their people are being killed.
Sorry for the bad cut and paste.
