As it was said, North Korea is years away from being able to fit a nuclear warhead on a missile and accurately fire it, let alone have an actual nuclear arsenal, the most they could do is start a war with the south, but they'd get their asses kicked by every single nation around ^^ All in all, They've been fucking irritating, and if things manage to stay out of developing into a thermonuclear war, then I wouldn't be agaisnt an invasion of North Korea.
