Look at his last term in office. Once someone starts to understand - and starts saying 'no', or 'we can't', they're gone. There's going to be a constant stream of new appointees that haven't a clue. I expect it'll start rocky and stay that way.
Also, I get your meaning, but it's 'mansplaining' only if you're explaining something that the other party already knows. Not sure what I'd call it here where it's an attempt to inform the willfully ignorant.
