That's how you know he's scared shitless. Also, his overcompensating tweets tend to be a great indicator of how small he feels. The bigger the wall of text, the more filled with lies/CAPS LOCK/insult/etc. - the more out of his depth he is, like a cornered animal screeching.
Plus, military seems to be quietly saying the loud part, as one could interpret the small signs of the parade. So if he can't count on them he can't rely on any dictator's biggest enforcing arm, the same arm that can easily crush ICE and all the co-fascists if it ever comes to that.
I really hope they don't get away with it in the end. Simply being removed from office without heavy consequences for all of them just sends the message that the next sleazebag can start to slowly carve a path on the shadows and attempt success where these grifters failed.
He already tried it during his first term, but luckily was inexperienced and mostly surrounded by people who reeled him in. Now, on his second attempt he's learned from experience, and surrounded himself with yes men, either by appointing them directly, or by firing and replacing someone else in a strategic position that could threaten him. Which makes him much, much more of a threat.
There won't be a third attempt from Trump, but you can bet the likes of Vance, Miller and so on will try to fill the void he leaves if they aren't held accountable. Heck, even Trump's son's have already floated the idea of following their father's footsteps. Evil is always lurking, waiting on a chance to pounce when prey is weak.
