It's very easy to not agree with the way the North Korean government handles many things, but you have to give them the benefit of the doubt that they are not doing it for shits and giggles. After all, they have been at war for over 60 years now. It must be obvious to any patriotic Korean that the danger posed by American imperialists who still occupy the southern half of the country is ever-present and growing. Someone must guard those walls.
These types of comments are becoming the norm on HN. Perhaps someone should write a script that can generate the reciprocal of the parent like this... it'd be a neat weekend project :d
