There is nothing worse than officers who climbed the politically correct, peacetime branches to achieve senior rank. Usually they are incompetent and historically when real war comes, nations suffer setbacks until they are replaced with competent warriors. The Joint Chiefs of Staff is just another woke Federal bureaucracy.
Trump is in awe of the military and has not exercised his power. Remember when he issued an order to ban transgenders from the military. He was openly opposed and defied by a Coast Guard Admiral. That Admiral incredibly was not disciplined or relieved of his command.
The modern illustration of that was the war in Iraq. It went badly or not-so-goodly until the political Clinton commanders werreplaced by the new officers coming up through the the ranks in combat. Then the “surge” happened which, in itself, was not decisive. It came as the politicals were phased out and the combatants had taken charge.
Then one day, Pearl Harbor was attacked and suddenly Billy Mitchell was a genius.
Trump needs to fire more of the embedded opposition.
