No, not unless they do something first; unless he gets talked into some insane covert adventure that may not end well. (Relaxing is not in my nature - I'm genetically paranoid.)
But if they do something first in a serious way, he'll go... well, ballistic is the usual (if somewhat ironic in this case) term, I think. The Military Industrial Complex (to use Eisenhower's term for the machine) stands to make a lot of money every time there's any sort of military action, so.... war is good business.
Seriously, what is there left to do to North Korea as a "sanction"? Financially/socially they are tremendously isolated (except from China), their people are starving....
