A riveting history of the nuclear weapon that is mostly about how dangerous they are, both to whomever is bombed with them, and to the user when they accidently fall out of airplanes (again and again). The story is gripping, but there is very little analysis. There are comments in the Epilogue pointing out that in an incredibly complex and dangerous system like our nuclear weapons and their command and control, an error rate of .000001% would still be unacceptable since the detonation of a 5 megaton device in Greensboro would be unthinkably horrible. Studies of mistakes in Medicine are similar, since mistakes occur no matter what you do, and they are usually completely unacceptable. I think one could also discuss the old conundrum, that the type of brave arrogant fast-acting no-nonsense guy who rises to the top in a complex organization like a branch of the military, might not be the best person to agree to have the safety of his weapons reviewed.
