Trump doesn’t really come to terms with anything imo.
Anyways, from my reading, his big speech was basically the set up to announce a national emergency but he was talked down out of it in the 11th hour. Which makes sense as to why in the days preceding they were sending out all these stalking horses.
Like invading Venezuela or firing Rosenstein, if Trump had his way I suspect it would of already happened but his legal and political team still seem somewhat capable of temporarily talking him out of his worst impulses. In the case of Venezuella he moves onto the next shiny object, in this case I think he ultimately does it with GOP encouragement. We’ll see.
