The USNI article and subsequent comments does highlight the issues. Since none of us (or for that matter the people commenting on the USNI article) really know the complete story it is pretty hard to know if in fact the Captain was grandstanding or if he had exhausted the channels available to him.
It is an unfortunate side affect of the current political climate that trust in the integrity of the professional leadership of all branches of the Government including the DoD has been seriously and deliberately eroded. The attributes of leading by example, self sacrifice and personal integrity have certainly been denigrated and ignored for the past several years by the very top of the Government in favor of rewarding uncritical and absolute “loyalty”. The current acting Secretary of the Navy is in the position after all, because his predecessor was removed for pushing back when told to execute something ( Gallagher) that clearly interfered with the internal maintenance of good order, discipline and the best interests of the Navy. And today’s news that the DOI -IG was removed for following the law demonstrates sends yet another message to the troops that the worst failing is not failing your troops or the mission - but contradicting the administration is absolutely a cardinal failing. So now is it any wonder that subordinate Commanders would question if the senior leadership really would do everything in its power to take care of their personnel if doing so was not in synch with the public utterances of the administration?
And if they don’t believe that - then those subordinate commanders do what they believe they have to get the right outcome for their troops, even if that means jumping on a professional Hand Grenade. Undermining the chain of command and rewarding obsequiousness has dire consequences- whether that undermining comes from the top down or from the bottom up and I suspect this is one of those consequences.
I don’t know what happened here or why an Officer with 25 years experience in his second command, commanding one of the premier ships in the World, would essentially knowingly toss his career. But I would suggest that it is an indicator that the trust in the senior leadership by the troops has faltered. In routine times - who cares? But when things start to get hairy - if you don’t believe the leadership has your back -then you do what you believe is necessary.
