Intense and horrifying. On the whole, I felt it was well written, though the beginning was a lot to slog thru. The fictionalized scenario - sort of like a war games theorizing of what a nuclear war would look like - was the good part of the book. The beginning was a little odd with the minutiae of detail, especially an entire chapter devoted solely to the names and titles of the people she interviewed - usually something that is at the end as a footnote, which I just skipped. 

I will say I disagree with her conclusion that the blame lies with the weapons tho. The weapons didn’t create themselves nor did they decide to launch or push the button to launch. I agree it’s not any one specific group of people - but it is humanity and our arrogance, vindictiveness, and hunger for power that’s to blame. You wouldn’t blame a knife for stabbing someone, you blame the person who did it. Same for this type of weapon. Only human depravity can do that. It’s insane we even have this as a possibility.
