Exactly. Trump tweets as if he is wholly disconnected from the government.
POTUS doesn’t micromanage. He delegates authority and then if he is not happy with results resignations occur. If he’s really unhappy he Boltons the employee.
There is a hierarchy and POTUS plays by the rules. Even with the ridiculously partisan judges that over reach POTUS operates by getting a legal opinion that supersedes them. If he operated as you suggest he should he would need to be emperor.
