You keep tap-dancing around the topic. How does the rank and file soldier decide?? Does he blindly follow the "duly elected" chain of command? Or does he follow his oath to the Constitution. Constantly repeating "cannot obey unlawful orders" like a mantra is just ignoring the question.
"But I agree with your concerns that four years of Hillary following eight years of Barrack may well have been enough to reduce the USA to a third-world banana republic. Especially with Congress returned to Democrat rule, and the courts to activist judges... well, that's a nightmare I'd rather quickly forget."
Unfortunately, my mind refuses to forget.
Sorry, but I'm not tap-dancing or ignoring your question, you are ignoring my answer.
It's the correct answer, it's the only possible answer.
All government agencies are charged with obeying and enforcing the law, period.
Commanders cannot issue unlawful orders and if issued such orders cannot be obeyed, period.
You seem to fantasize that means every soldier or police officer needs a lawyer following him/her around to certify that every order issued & received is, indeed, lawful.
That's ludicrous -- broad outlines of lawful behavior are well known, with special training for special situations.
But just so we're certain, you do realize, don't you, that action-adventure movies like, say, Jason Bourne are fantasies?
Fantasy, not real:
