Yup. Some of us knew that, especially after the steal in November, he had no power, because he had no support. [1][2][3]
There wasn't anybody left who was going to follow any of his orders. Went from the vast majority of the fed gov against him, to everyone but perhaps a couple of people (ex. Pompeo, Meadows) and they...had no power, especially after the steal.
He was literally, a man on an island by himself.
...and, tangentially, this notion that milley had such grave concerns that Trump was going to launch a nuclear war, so he had to subvert him and conspire with the Communists in China and Trumps political rivals...is pure B.S. milley knows full well, at a minimum, Trump couldn't launch a nuclear war all by himself and that Trump was the most anti-war, get out of foreign entanglements President the country has had in well over a generation.
He knew nobody was following Trumps orders anymore, so the entire premise was moot at the root.
I think Milley is psychotic and should be relieved. He might actually believe all that wokest BS he spouts. This is the reason you must have civilian leadership, even a insurrectionist traitor like Biden is safer than a harebrained woke General Jack Ripper screwing around like this and starting WWIII.
