North Korea has brainwashed leaders practically trained to be malicious. North Korea has already demonstrated it's impressive failures in nuclear warfare, and I doubt if they have many nukes to make use of. I'm sure if needed, Japan and the United States would be willing to assist South Korea in suppressing North Korea, and that's just the start. The allies of both would most likely join in as well. North Korea doesn't stand a chance, and the frown-worthy fact is that they don't realize it. And if something crazy happens like China joining the 'war' with North Korea, it's just going to bang up China as well (not saying China would, as they heavily rely on the US and several other countries for much of their governmental income). The talk of this war, which has been going on for 63 years, is ridiculous, as it's really not going to turn out well for North Korea and any of their possible allies. Eastern nations such as the United Kingdoms, France, Germany, etc. would bring in way too much support, I'd predict, against North Korea and those said possible allies, which is very unlikely to see. The point is, North Korea can not pose as a serious threat. We're not going to see a Korean Hitler.
