Lemme take a wild guess. You live in either Wisconsin or Michigan.
Let's not panic. Nukes are not as dangerous as you think.
Don't forget, more than 1000 nukes were set off just 65 miles outside of Las Vegas and people lived there the whole time.
Nowadays, nukes can be 'tuned' to produce lower amounts of radiation and more blast/heat - sort of the opposite of a neutron bomb which produces searing radiation and little blast. Set off just above the hole or near the top, NOT deep inside of it it will ostensibly fuse the rock and seal it...or not.
People have been fooled by the paranoid left about nukes. They say that if India and Pakistan went to war with nukes it would be the end of the world. You should laugh when you hear this and remind them of the 1000 MUCH BIGGER nukes that the USA set off just outside of Vegas. People used to watch the blasts from their hotel rooms.
According to the left-wing environutjobs, Las Vegas should be uninhabitable for the next 1000 years. I was just there and I'm fine.
Deepwater Horizon is approximately 50 miles offshore and far underwater. A nuke can safely be detonated there... but would it work?
