A nuke probably $8mil. They will likely have a damn good reason for whatever they are buying if it's expensive enough.
(I can't see a random unstable nutcase coming up with $8mil for a nuke. It's even hard to imagine someone like that coming up with $1,000 for a machine gun.
You have no imagination or common sense. You think there are not unstable people that are rich or have vendetta or agenda. You're as naive as they come. You must just be a troll to say this utter nonsense.
