Incredibly weirdly put-together book, with tons of fairly dry historical detail interspersed every now and then with a more NdT-esque essay. I was expecting A) more about the present-day state of the space-military complex and/or the details of our current abilities or B) more in-depth explanations of the technologies that enable these capabilities. In both aspects this book fell flat.

What the book did do was spend a very, very, VERY long time going through just about every historical application of space/time science. It went through every incremental advance in timekeeping, optics, guidance, detection, etc. It went into exhaustive detail of how we managed to define longitude and latitude. I found myself skipping many pages because I couldn't bear to read about yet another hundred years' advancements in spyglasses. The major point, that all of these things were generally developed because there were military applications of them, was made very early, and everything else was just example after example, like a history book or a term paper, with little insight or analysis.

In the end, its self-described scope and "story arc" was so poorly defined that it ended incredibly abruptly, leaving me staring at the page dumbly for a long moment. Then I was just relieved it was over.
