And why wouldn’t they use nukes? Such a war is like a murder suicide why would they care how much misery they cause?
If they truly think they’re committing suicide in attacking the South, then I suppose they would use what they have. I think they may be a little “off,” but I don’t think the Iranian-class insane. Maybe they are. Seoul will be the first place to find out.
Even if the Norks use nuclear weapons, the vast majority of the citizens of Seoul will not be killed, but will instead be very angry. I’m glad I’m not there.
