I notice that the little fat boy from the North, Kim, is back in the news. Making threats, acting like the spoiled brat that he is. Suffering from a severe case of overactive hyper-stupidity disorder. I mean, c'mon, he can't even keep the lights on.
There is no sense bombing them back to the pre-industrial age. That's about where they are right now.
It would be best to ignore the little pissant, and send back-channel messages to his generals. If little Kimmie meets and untimely demise, we'll see what we can do to help with lights and indoor plumbing. That would be much better than what they have now.
