While the post you're replying to is a little tongue-in-cheek, it made very valid points. What you are proposing is to forget all lessons we should have learned from the past: that meddling with sovereign states is very short-sighted (see Libya, Iraq, Egypt, both before and after the recent wars); that we should not use weapons just because we have the impression we have more than the others; that attacking a country generates hundreds of thousands of deaths and millions of refugees, which neighboring countries have to manage afterward; and that the long-term implications are unknown but usually very painful (see Iraq, Afghanistan, Egypt, Syria), including for neighboring countries. Plus, your mention of the lynching has little to do with the reply and the subject. And there are other countries that practice unjust imprisonment and torture, I might mention a few in the West. We can't do anything about the past except remembering it and practicing its teaching. If by "doing something about the future" means bombing NK, then the future will have millions of refugees pouring into China, Russia, and South Korea. At least we should ask an opinion to the "reasonable" countries that border NK.
