The author is dreaming. There has been plenty of provocation over the last 60 years to put an end to the Norks. The USA could have defeated China in 1953, but instead we turned wimp all of a sudden. China! A bunch of savages with guns that couldn't shoot straight!  The UN could have completely isolated Nork but, no, we all sold our souls to the oodles of cheap Chinese slave labor, to which we are still hopelessly addicted today. And the Chi-coms absolutely forbid messing with Nork. Hell, we are even too afraid of China to recognize Taiwan as its own nation! 

So, no, there will be zero attacks on Nork unless the Chi-coms allow it, and I can see no good reason, yet, why they would. Trump could probably figure out an incentive, but then we trade fear of Nork to increased fear of China. This is why no deal has ever been struck.  

We ought to say screw it and call China's bluff; but our leaders are even bigger weanies today than they were in 1953.
