They aren't bat shit crazy, but they tread that thin line. They are playing a bluff in my opinion, and Pres, Trump called them on it, unlike other world leaders. All we can do know, is see how far the PRNK wants to go with this. This is the first time anyone has called heir bluff, and it has them worried. I doubt their guidance on their missles is very accurate, but they can do damage if we failed to intercept anything they may launch.
