1st of all, WTF did Russia and China do to NATO?
2nd, how the %&$& would a conflict involving ALL OF NATO, RUSSIA, AND CHINA be a small conflict?
3rd, NK has a lot of weapons, oh and btw, they have in fact, lasted 3 months against 'the west' in a full scale war. It was called the Korean War, you may have heard of it?
4th, China actually HAS 21st century technology and although some western nations' military technology may still be better, you can beat they would give some of those nations a run for our money.
