Trump being the Commander-in-Chief has no choice. He cannot back down lest he be seen as CiC in name only which would be a very dangerous. Our adversaries are watching this closely for signs of weakness.
I’m not sure it rises to the level of insubordination, but what do you think Trump should do with those above Rear Admiral Green in the chain of command? Get rid of all of them?
Maybe he should. I don’t know, but I trust his judgment.
