N. Korea is about the size of an avg state in the U.S. You know how petty it would be to start a war based off of threats lol. It's easy to talk the talk but we all know Korea can't walk that walk. If they were really about it they would've been invaded. BTW we have our own racial, economic , etc problems here so why would we be stressing overseas? S.korea can't fight they're altered mirror image? LOL and if we jumped in that would give other countries the okay to jump in and we still haven't finished with these Isis that have actually captured and killed Americans. What's up with that ?
