I believe that also due to their fatalist belief about some Imman crawling out of some well. They are insane enough to push us to their extinction. That's why I say attack their nuke facilities, yesterday. While we're at it, take out King John Um's facilities. With a barrage of bunker-busters and cruise missles and tactical nukes, Fatboy wouldn't unleash his armor installations on Seoul, and probably being eating his fingernails down to the bone in his bunker.
