I think there is ample reason to believe that this whole NK thing is Trump's "wag the dog" instincts run amok.

The danger here is that Trump believes he has the military intelligence, National security intelligence, and native intelligence to KNOW that the only results of his fighting words will be either military engagement in which NK will totally lose, and the US will totally win, or a backdown by NK and Trump will reap the rewards of being a glorious tough guy leader.

The danger is that Trump is wrong.

The danger is that Trump "presidents" based on his beliefs that what he thinks is correct, that what he does and says is  good, and that what he believes and does will lead to "successful" results as he openly defines them.

The danger is that we have 7 months of evidence that, at the very least, he's wrong about most things one heck of a lot.

Trump can't get Americans to do what he wants, even if he uses intimidation and shaming from his bully pulpit.  Jong Un will?
