Their people are not going to rise up. I've seen several documentaries on NK and even though their people are severely malnourished, they still praise the Kim Jong family as saviors of Korea and warship them like Gods. The entire country truly believes that America's spend everyday planning the next nuclear strike on NK. They are so brainwashed and the entire country is literally a huge prison camp. They hate Americans and think we are completely overwhelmed with thoughts of nuking NK.
I'm not sure what needs to be done to resolve this issue and I don't think anyone does. Its really up to Kim Jong Un.
I have been on several differant forums, and seen many differant commentaries at the bottom of news articles where Nuke them was exactly the sentiment being conveyed as a means to deal with them. All of my dad's friends who were Korea war era guys all believed we should have killed them all, so If N.K. has people reading posts on web forums, news articles or commentaries off the internet, they would think all we wanted to do was destroy them.
If N.K. had been imposing sanctions on the US since the 50's and had isolated the US from free trade with Mexico and Canada, and our population was starving because of it, I would refer to them as the agressor, and hate them as well.
Funny how we are so one sided with our thoughts.
