Gaddis' book does a fairly good job of synthesizing the conflict, and there's enough info there to instantly earn you a few levels of armchair historian. I personally came away with the impression that he spends more energy detailing Soviet misdeeds than western ones, but he by no means commits the fallacy of omitting or glossing over American culpability where it existed.
(Also, it isn't a book, but for some perspective on some of the key moments and the overall trajectory of the Cold War from one of the architects of Western policy at the time, I cannot recommend the Errol Morris documentary The Fog of War strongly enough.)
