The same Military Times Pentagon approved survey showed Trump's disapproval by active duty troops on the cusp of Obama's latest reflective negatives as of December last year.
There's a lot of Red in both boxes at this point as Trump continues to move into Obama disapproval territory. By November Trump may well be dead even with OB in disapproval by active duty forces across the board -- or to surpass OB.
As to your post I'd simply reiterate that -- as any officer or senior NCO will attest -- without the UCMJ that Trump is deconstructing the armed forces lose their discipline, good order and worse their effectiveness. We know the reality of military forces from ancient times to the present and beyond is that we either have a rabble or we have a disciplined armed force that is in a continuous state of good order and mutual respect among all ranks. UCMJ v Trump is in fact the Pentagon's bottom line and it's clear to me Trump knows this, which is why he's fundamentally finished with LTC Vindman and the twin brother LTC who's a lawyer.
Trump's Troopers of the Right are doing overkill trying to trash the LTC because Trump is not going to smack the hornet's nest at the Pentagon over the UCMJ and Vindman who is assigned to the Office of the chairman JCS. As far as we know no one at WH wants to grab their butter knives and head out to the OK Corral on this one.
