Query: -Good Ideas but not enough depth-

I am a dedicated history and counterfactual history enthusiast. I have read just about all of the alternate history I can lay my hands on - I think it's a wonderful means of learning how close we've come to disaster. This book was a fascinating read in terms of topic, but had very little to offer in terms of analysis. Each short essay explores a different possibility, and granted many of them go into some depth explaining how the possibility might have come to pass, but the level of depth included for each scenario is truly insufficient. Kenneth Macksey, on the other hand, really understands how much information is necessary for an alternate history: in his books, The Hitler Options, and Invasion, he gives excellent alternate history accounts. So does Peter Tsouras in Gettysburg. This book just doesn't give enough. The best thing it has accomplished has been to give recognition to a valid means of studying history.
