North Korea

Is all the crap coming from North Korea for domestic consumption? Probably, but who is the target audience? Is it the average North Korean? Perhaps. Is it for others within the leadership? The selectorate? How big is the North Korean selectorate? Is this kid just insane?

One of the fall back arguments against DPRK having Nukes, or at least Iran having Nukes, is that they're irrational. 

I disagree. This tantrum isn't meant for domestic consumption. It's meant to instill uncertainty into the  minds of analysts. This is rational behavior. It's risky, but the risk has to be taken. The American response has been satisfactory. All DPRK needs is the US to say and show that it takes the threat seriously. The US responded ideally. Why it's almost as though we've given the Nutcase face sending B-2s to pratice killing him.

And so, let's just hope he isn't insane.
