I agree with @bigpanda I have heard that even our troops in south Korea will be a meier speed bump if we were to be attacked by the north. I am most concerned with north Korea's chemical weapons. Nukes imo are nothing compared to chemical weapons. We also need to think about what we will have to do about the entire north Korean population that has been subjected to generations of brain washing. My idea to stop Kim is to remove his only way of repressing his people and that is blaming all its problems on the west and south Korea. So if we could give the people free WiFi and our old cell phones, I think the problem would solve itself in a few years.
