Quote from CaptainObvious:
For the U.S.? We don't even belong there far as I'm concerned. Let the North and South duke it out on their own. North Korea will sell arms to terrorists regardless of our presence. Should a North Korean nuclear device find it's way into terrorist hands and that device kills Americans, and we can trace that device back to them, I would then support a full scale nuclear strike against North Korea. Until then, we have no business telling them or anyone else what they can and can't do. My message would be clear and simple. Kill each other to your hearts content. Kill one American and we will unleash hell against you, taking no prisoners and paying no attention to the two stupidest words with regard to war. Those two words are collateral damage. There's no such thing in a just war.
