At sort of the same point in time as St. Donald of Mar-a-Lago's first term, his chief of staff was General John Kelly. I tend to think General Kelly was a voice of reason and restraint that is completely lacking in St. Donald's second term.
Completely unrelated story: When I was a small boy, 2nd or 3rd grade, my father's commanding officer from WW2 visited my Dad in our home. This commanding office was Lewis B. Puller. Because he was visiting his daughter at Camp Lejuene, the base commander had made a car and driver available to him, so he came up to visit Dad at our home. Gen. Puller was dressed in his dress greens. And he had three stars on his uniform signifying he was a Lieutenant General. And he told me that he had retired as a Major General, but because he had served in combat, he got promoted to Lieutenant General after he retired. I asked why a Lieutenant General outranked a Major General when a Major ranked a Lieutenant. He laughed, said he didn't know, and added that four star generals are just called Generals.
