I have been thinking about that, and it seems to me his public utterances have been calculated to give his enemies something to chew on while he goes about the business of "winning" whatever it is that is in his sights. It is a common management tactic.
If this is the case, then if you pay attention to what he says rather than what he does, you are following the decoy.
This isn't business, though -- it's politics: "the art of the possible." In politics a great deal hinges on what one says; and any difference between what is said and what is actually done, is fodder for the opposition.
Besides all that, to the extent that Trump's behavior drives the media narrative, his ability to get things done will suffer accordingly.
My view of him is unchanged: that he's a thin-skinned and undisciplined narcissist. His behavior during the election established that beyond a shadow of a doubt. Thus my lack of confidence in him being able to reign in his behavior for the good of the country, and even the world.
