I suspect that the review is wanting.
I would hope at least that the book makes note of the effort expended in defending against bombing raids, and to what extent that facilitated the achievement of tactical air superiority in support of ground forces.
You're also playing a game of "what if?" if you try to make a general argument that strategic bombing was ineffective. An undisturbed German industry - not forced to disperse production, put things underground or build guns and fighters to defend the Reich - would have been able to produce more submarines or long-range missiles. How many, and what difference would it have made?
