He should know where the “buck” stops. A private can buck the responsibility up to the sergeant. The sergeants can buck responsibility up to the officers. Officers can buck it up to the generals. The generals can buck it to Washington. The buck stops at POTUS.
POTUS HAS THE RESPONSIBILITY TO ENSURE THAT EVERY GENERAL, OFFICER, SERGENT, AND PRIVATE IS DOING THEIR JOB. That is why they call POTUS, “Commander in Chief”.
