This book and a few related articles have riled political Washington for the past week. Sanger obviously had very high access, has sourced his open facts very well and wrote an excellent book. Here's a great inside look at the past three years of diplomacy, covert action and internal Administration deliberations.
I won't give another summary here; others already have. I will echo another reviewer's irritation at Sanger's introduction of Obama as "typical dovish Democrat" and transition to "Hawk." Sanger needed to tell a story here; like many in the Washington press corps, he is shocked (SHOCKED!) to find the President would act like either a "Hawk" or a politician. Sanger has difficulty moving away from that bit of conventional wisdom, an understandable problem given his own position as a New York Times reporter.
The only other point the book seems to lack is a deeper discussion of the legal and geo-political ramifications of nation-states' use of cyberwarfare in peacetime. Sanger brings up the point of nations using military-designed computer programs to weaken or spy upon other nations. Is this an act of war? Where is that line to be drawn? Sanger asks the question but doesn't search very far for his own position, nor does he look to any other outside voices on the subject.
So, we have an extended news article here, focusing on several challenges to the United States around the world and how this Administration has met them, for good or ill. Sanger doesn't take much of a position of his own, but this won't stop reviewers, talking heads, the left-wing blogosphere or right-wing shriek radio from spinning this book to their own ends. I believe this book is worth the money to read and decide for yourself.
