“Biden” is working from a movie-set oval office in CA. He’s just reading a script given to him by good guys. “Biden” himself is a good guy, an actor. The good guys are not going to have “Biden” remove the troops.
So, yes - you are exactly correct that “so something else may be going on”.
No doubt that Biden is an actor.
Who is really directing him? Obama I suspect........pretty sure it ain’t Hitlery!
