I Think I Understand Trump's Play Here (North Korea)

With all the seemingly insane things coming out of the POTUS' mouth I think I still get what his play/plan is with all of this bluster. Note, that I also think he may regretfully underestimate the North Korean regime. I think that Trump has seen NK continually make empty threats towards the US, heck they "declared war" on us a year ago. So his plan to revive his sagging poll numbers is to manufacture a crisis and make it seem like we need a strong leader. After all the tough talk North Korea will likely back down again and Trump will go around and say his tough talk and leadership was the reason. They will then use this "victory" as a notch in his belt and try to parlay that into moving the poll numbers more in his favor. Not sure if it will work and may we all pray he doesnt push NK too far.
