Which country is going to bother invading N.Korea?? It still has a strong military it will crumble any couturiers economy if they have war with North korea.
i doubt that war would break out Between north korea and another country. north korea is strong and all, but it lacks a good enough society to do it. besides, i dont think north korea has the guts to attack america. remember world war 2? japan fought well, but was crushed by america (im not being racist or anything, my parents are japanese and american)
