Copied from my post: Notes on "The Myth of the Nuclear Revolution" (Lieber & Press, 2020)
I recently completed a graduate school class on nuclear weapons policy, where we read the 2020 book “The Myth of the Nuclear Revolution: Power Politics in the Atomic Age” by Keir A. Lieber and Daryl G. Press. It is the most insightful nuclear security book I have read to date and while I disagree with some of the book’s outlook and conclusions, it is interesting and well written. The book is also very accessible and fairly short (180 pages). In sum, I believe more people interested in nuclear security would benefit from reading the book.
I liked Command and Control, The Doomsday Machine, and The Dead Hand, but didn't get many interesting ideas from The Making of the Atomic Bomb.
Only some parts are relevant to nuclear risk, but Spy Schools by Daniel Golden taught me some interesting stuff about science and espionage.
I also (really) liked The Doomsday Machine and The Dead Hand, and felt that The Making of the Atomic Bomb was a bit of a disappointment. Haven't read the other books Ryan mentions.
I also recommend American Prometheus, a biography of Oppenheimer (although it focuses too little on the science, relative to the politics). The author has just published another relevant book, Gambling with Armageddon, which I'm looking forward to reading.
Not a book, but the multi-part CNN documentary, Cold War, is excellent. So is The Day after Trinity.
