Query: Where it all came from.

The other reviews are excellent and summarize this book well. Reading it shows how deeply ingrained militarism is in our society. It probably began with the "splendid little war" with Spain but was reinforced by the weird "preparedness" movement before WW I. It has become all to familiar now, the hysterical invention of non-existent threats, the lockstep propagandizing of the press, the sheer incompetence of the national leadership of both parties in foreign affairs. If you respond well to black humor it is also very funny at times.This book was very influential in stimulating the isolationist movement in the thirties before WW II. That may be an example of how not to learn from history. It's like the tendency of the military to prepare for the last war. I can't blame Millis for the misuse of his book in that regard.
