If North Korea fires a missile into South Korea, we are going to be involved. If they fire a missile at the United States, we will be involved. The big difference or question is what is China going to do. In the Korean Conflict, the U.S. had no relations with China. Now, we recognize the country. Many American countries have manufacturing facilities there, and China has investments in the United States. Without the support of China, North Korea is a much smaller threat than it was back in the 1950s. If they launch a nuclear bomb, it will be destroyed over water and some country may fire back. We do not need to get involved in the internal politics of North Korea, but if they threaten other nations, we have to play some part. I do not want to see us in another war. However, I do not think we can just turn our backs and pretend nothing is happening that could threaten world peace or our own safety.
