I watched 20 minutes of this and realized I had to go and feed my fish.
Fwiw, if anyone wants to see firsthand what a 100 kiloton nuclear explosion can do, sign up for the Nevada National Security Site public interest tour. It's free and will blow your mind. My wife and I took the tour 6 or 7 years ago and during the 8 hour tour were shown things very few people have ever seen. We weren't allowed to bring anything other than the clothes we were wearing, no cameras, phones, not even a pencil and paper. The site is still active (and radioactive) and anyone entering must pass a background check first. It took us 2 years to be put on the roster. I won't discuss specifically what we were allowed to see but it changed the way I think about world events afterwards. Google it.
