This book lives up to its ambitiously broad title, and overall I was really impressed with how it managed to tackle so many different aspects of the relationship between war and gender without losing depth. Goldstein's book is an attempt to gather a lot of knowledge about this relationship that has been scattered between disciplines (mostly Biology, Anthropology, History and International Relations) and organize it in a way that allows him to answer the question: why is it that, "despite the diversity of gender and of war separately, gender roles in war are very consistent"?
Though some portions of the book aren't particularly important for my thesis, I couldn't bring myself to skip those parts because it was all so gripping. Though the book is very well researched (there are 65 pages of references at the end, all relevant), it is written in a clear and logical way that allows you to follow his line of thought perfectly. Even the way he went about debunking some myths most of us want to believe in (sorry everyone, there is no evidence of matriarchies or Amazons), his measured untangling of evidence is so fascinating I couldn't stay mad.
Most important of all, Goldstein managed to convince me of his main conclusion, and I think it's a pretty game-changing one: though this is a complex system that goes both ways, gender is more an effect of the war system than a cause of it. Although some biological differences assure that men, on average, are stronger than women, that in itself would not explain such a strict division as we see in virtually all cultures. So a division is created where boys are toughened up, and taught that manhood is something to be earned (a man card, if you will), and cowardice is a surefire way to lose it and get tossed into the "other" group: women. So men are taught that there is a fate worse than death: to be a "pussy". It's a great way to convince them to go to war, because let's face it: war sucks. You have to convince a bunch of boys that it's worth it, that "cowardice" is an awful thing. And so cowardice is equated to "failed manhood", which is equated to being a woman, which is, in every society, not as good as being a man. And so gender becomes the greatest code of domination, both at home and at war, where the enemy is feminized. Even though most men don't fight wars, all boys and girls are socialized in accordance to this system, because the possibility of war is a constant.
Anyway, I thought it was pretty genius. The one criticism I have is that it's too American. I mean this in two ways: (i) most examples from the 19th century onward are focused on the US (and to a lesser extent, Europe); this is particularly noticeable on the subject of the world wars, where not enough attention is given to the Pacific War; (ii) the methodology is very American in the way he lays out clear hypotheses separated by chapter, and with a neat table at the end of the book ranking the status of each hypothesis. Though this makes for an elegant system, his fixation on trying to answer his question in a neat way made for unnecessarily timid conclusions. Thankfully, on his way to answering the question, he goes deep enough that we can draw our own conclusions.
