Most people think it was a good call but it also may have compromised the safety of the carrier because now it's known they may be operating under less than perfect condition.
It's pretty clear he was canned by a political appointee for political reasons.
Also, although he was relieved of command, he wasn’t “fired” or “canned” or discharged from the Navy. He will undoubtedly go into an early retirement with a full pension at his current rank of Captain. That doesn’t change the fundamental unfairness of how he’s been treated, but he’s going to be fine. And I think he knew and accepted the consequences of his actions.
Or was he discharged on evidence or assumption he leaked to the press himself?
(And not just in the Navy)
From all I could gather from Europe, I believe he acted as a human more than a robot and under the given circumstances it was the right call.
And in order to actually act they had to leak it because silently acting on it involves getting a refusal from their commanders and also writing an email. It's monkeys all the way up.
