I got a question. If they have the technology to pinpoint any person in the world from space and kill them or find them, what's to stop them using this technology to find anybody on the planet. I still see the best hope is making some sort of underground bunker yourself maybe for better coverage, or am I wrong. I have these visions for years about going underground which some sort of habitat above ground with camoflouge on top like grass, like the hobbit house. What do you think, about the technology I mean.
