Annie Jacobsen has put together what is basically a well-researched novel to guide the reader through the mechanics of nuclear deterrence. Rather than having a simple recitation of facts of how elements of deterrence (or the failure thereof) would work, she creates a fictitious scenario that weaves those explanations together into a narrative. The result is one of the most compelling things I’ve read in years.

I’ve seen repeated criticisms of the book mention that some elements of the scenario aren’t well developed, but the author’s goal was to illustrate what a nuclear attack would look like, not write a 1200 page Tom Clancy tome. There are elements of the story that can be a little far-fetched, but they’re still reflective of real plans that real people working for our real government have really put in place, and some of those plans are pretty wacky.

The text is dense with technical details - what systems are deployed, how they work, and what they can’t do. The “can’t do” part is especially important as a lot of the strategy of nuclear deterrence originates from blind spots and shortcomings of various sensors, weapons, and safety systems. The author does a really wonderful job depicting the sort of confusion that can come about when you combine technical weaknesses with human indecision.

There’s great insight into how the structures of the military and intelligence community come together in these scenarios. What the organizations are, who the organizations are ran by, what the role of that organization is and isn’t, and where those people and organizations are physically positioned are explained in accessible detail. Historical elements about how those organizations evolved are woven in for context.

I’m deducting one star because the author routinely throws in embellishments that can be a little distracting. The is absolutely no reason to attempt to embellish the effects of a nuclear weapon - it is truly mindbogglingly horrifying. Those embellishments elicited an eye-roll when I would have otherwise just sat and reflected for a moment.

Highly recommended for anyone interested in national security. The abundant references also serve as a great guide to further reading.
