Logic would dictate that would be their next targets, easy to cause the most damage to the planet, radiation and not much security, any suicide bomber even a child can walk in there and kaboomb. Year after year, country after country etc etc.
LRH was annoyed that radiation could affect his work, how could something from so far away affect him and Scientologists? He wrote a book, All About Radiation there is no known cure for radiation poisoning, so everybody will die a slow painful death.
I'm sure some people will survive, they will go into their bomb shelters that they bought.
I have no idea how mankind, the human race will survive with radiation in the water supply? If you drink it, you die, if you don't drink it, you die, pick one?
Currently people recommend Reverse Osmosis to handle small particles but Nuclear Power Plants one after another, the radiation pollution will just get bigger and bigger and bigger.
It's battlefield earth and the it's over in 9 minutes is when the planet stops spinning and falls like a rock, it's explained on my scilon website. For some people they will read into it and flip the 9 and you get what? A 6.
