Elon Musk is an attention starved and has the mentality of an impulsive spoiled child. Slava Ukraini was trending, so he wanted to insert himself into it to get attention. Probably thought Ukraine would lose so he gets a little attention for trying to help these guys fighting the good fight before they were ultimately crushed by Russia.
But that didn’t happen. Ukraine continues on and what he thought of as a little in the moment publicity stunt obligated him to helping Ukraine. While most people would happy with the result, but scared little child Elon Musk felt he was in over his head. And being the impulsive child he is, started doing impulsive shit and interfered in an active military conflict, compromising an ally’s mission.
It’s hard to say how much DC is in the know. It is a new tech, glitches happen, so they might not have suspected Musk was the glitch in the system.
