Apparently the N. Koreans were unable to miniaturize a nuclear device. However they have made great strides in fitting them in their hats...
As a secret weapon they found that the hats will hold enough rice to feed a soldier for a year. Soldier pictured here with a year's rice ration in his hat...
Apparently North Korea is also pissed a China for not backing them
the attached cartoon ran in Beijing Official Chinese Government Newspaper, Xinhua. North Korea is seen as a annoyance state to China and China has come out against NK military threats.
So I uploaded a video(s) to give you a better perspective of how seriously we take North Korean antics and their threats.
The threat of Violence is real, but we have to remember that NK has a EQ of a 5yr old.
