Honestly this book was more amusing science fiction than anything that felt like a real analysis of future events. The author obsessed over how vital it was to control the sea lanes, and then immediately predicts a variety of wars based on control of space showing how, in a world where space based operations are possible, control of the sea is meaningless. He then however immediately switches his predictions back to control of the seas ignoring his prediction for an even greater militarization of space.

Interesting, but perhaps not truly informative.

The problem is that his predictions for future society do not include the titanic spread of peoples around the world. He forecasts problems in the American southwest with hispanic immigrants taking over, but he forecasts these problems to occur in 2080. By 2080 perhaps 30-40% of people will be multi ethnic, and the number rising at incredible speed. Also, he predicts these vast wars between major first world nations. By 2020 I imagine most people will know as many friends outside the country as in it. Going to war with say, Japan, would be like San Francisco declaring war on Los Angeles. A battle between friends and family.
