I'll wait to hear why everybody under the military legal code will somehow risk being charged for insubordination in military court, especially when military chain of command has already seen two officers get fired by Obummer for defying his orders regarding Benghazi.
"Because I scream so and arbitrary pessimism is 'realistic'" is not a valid argument.
I'm going to give you a real quick lesson on power. Power is derived from force and that is it. Ultimately, if a 4-star general refuses an order from the President and no one with a force strong enough to arrest then punish the general, nothing happens.
If Trump declares martial law, there is a good chance you could see insubordination from higher ranking military officers. Unless Trump has a strong enough force willing to arrest and punish those who won't listen to him then Trump won't get anywhere.
You don't know anything about the military bill of rights, do you?
Laws are meaningless right now, that's what I'm trying to tell you. We've past the point of laws mattering. All that matters is who has the power.
