I'm surprised commentators didn't pick up on the implications of his speech. He was putting Washington on notice that he fully intends to carry out his campaign promises - all of them. He was speaking both to his supporters who put their faith in him, and Washington insiders, most of whom didn't. He is unwilling to  let anyone off the hook with some kind of Can't We All Be Friends approach.  He boldly set the dividing line, either you're with us, or against us. And he expects everyone to get to work now.
