People now realize that their views of North Korea are far different from how they really are. People see the country as a dictatorship wracked by poverty, but in fact, they at least have enough money to train these so-called 'cyber warriors.'
It brings the question: what else is North Korea hiding? Maybe they are truly more advanced than we thought before, and that their threats aren't empty. Their nuclear threats may have no substance to them, but if they have the capability to bring an entertainment empire like Sony to its knees, who knows what they could attack next.
