the book is proposing this thesis: that the most famous battles of ww2 did little to influence the course of war. it was the production/destruction battle that matter the most, and most of this battle was fought in the air and on the sea, not on land.
the thesis is well presented and convincing, the numbers support it, even if sometimes seems to be contradicted by other factor (human wrong decisions, shortage of skilled pilot for example).
sometime i have the feeling that the author is quoting the same passage at least twice in the book, either his own words or other people's comment. and what i mean is not 'the same idea', but exactly the same words verbatim.
there are also some rare and minor editorial errors, but the overall product is good.
a must read for ww2 buffs.
