Because Trump isn't going silently into the night, and he's still got way too many unilateral powers (EOs, pardons, commander in chief, and the attention that goes with all that), and he's proven over and over that he'll strike out at anyone if he feels snubbed, even if its against the common good or moral decency.
I am not concerned about Trump's wrongful exercise of his commander-in-chief power because military leadership is hypercognizant of his unbalance such that they will refuse to execute any order he issues if it has the merest semblance of an unlawful order.
In November 2020, during the dedication of a military museum, Chairman of the Joint Chiefs of Staff, General Milley, reaffirmed the military's commitment to the Constitution.
"We do not take an oath to a king or a queen, a tyrant or a dictator. We do not take an oath to an individual...We take an oath to the Constitution."
Who was General Milley thinking of when he said this?
The answer to my rhetorical question is that he was thinking of President Trump.
"We are unique among militaries. We do not take an oath to a king or a queen, a tyrant or a dictator. We do not take an oath to an individual. No, we do not take an oath to a country, a tribe or religion. We take an oath to the Constitution. And every soldier that is represented in this museum, every sailor, airman, Marine, Coast Guardsman, each of us will protect and defend that document, regardless of personal price." General Milley
