Could the N. Korea leader really be that smart? Mending fences with South Korea to isolate donjohn and make him irrelevant? Smart, right?

I don't know the degree of Kim's intellect but I think it is a definite end run around the large derriere of donjohn. The best rhetoric is to just ignore him and make nice with south Korea and move on. Don't acknowledge his threats or attacks. He is after all a dotard. You don't expect much from such a one so why waste any time  on donjohn? Thank you for your reply.  Even if you disagree mightily it doesn't matter. None of us really knows what the he** is going on. It is all conjecture and anyone's guess is as good as anyone's. :)+
