He's president. Not dictator. That means he delegates. He gives ideas of what he wants and legions of interns write it up while signing all the shit that heads up the chain to his office. The U.S. president is glorified paper pusher. All the "important stuff" you're probably thinking of has either (a) already been delegated, or (b) isn't actually within the authority of the office. He probably spent a grand total of a minute expressing his desire for this to end.

You clearly haven't a clue how bureaucracy works.
