Not that much uncertainty, really. When he does something insanely foolish that embarrasses his whole country and is called upon to apologize and be contrite, to be constructive and redress his failings, it is certain that he will double down on whatever idiocy he started on.

Witness his most recent dressing down of Brennan. Brennan says Trump should watch what he broadcasts thoughtlessly on Twitter, and without thinking, Trump launches into an attack on Brennan, accusing him of ongoing incompetence and leaking sensitive documents.

I'm pretty certain that pattern won't change.
