What do you want to do have America pay outrageous fees for minerals and resources by having them all sourced from other countries? Hell yeah! Let's put more Americans out of work and screw the economy!
And as far as nukes? Even in the early days of testing they could differentiate between nukes and natural quakes and considering that these faults are really really old by geologic standards I'm pretty sure if a nuke was gonna trigger 'Te Big One' it would have happened in the nuke testing heydays. More to the point, no one cans set off a nuke nowadays without seismographs around the world identifying where and how large it is.
Relax there partner.
I only asked questions. You are letting your imagination run amok here.
