Things aren't going well for the DPRK. If wanting to be a laughing stock were its intention, then it has succeeded splendidly. Otherwise, the last few months have been a complete failure.
Meanwhile it is a golden age in the ROK. For the citizens of the ROK life has never been better. That's not to say that life is perfect in the ROK, and that significant problems (corruption etc) don't exist there. But the ROK is confronting these problems and looking for solutions.
