The book predicts a world war in Europe caused primarily by class struggles, albeit about a decade earlier than what actually happened, and with England allied with Germany and France allied with Russia. The heroes of the book are socialists lead by a mysterious figure known as Natas (was it deliberate that this is Satan spelled backwards?) who is driven by an obsession to return control of the world to Anglo-Saxons. Griffith seemed to think that airplanes were sufficiently difficult to produce that no other entity would have them, thus giving their owners vast military superiority. The socialists use their air power to essentially wipe out all opposing forces and install a world government. The socialists are pretty ruthless in their decimation, purporting that only by doing so can they instil the true horrors of war in people so that no wars will ever be fought again.(Goodreads)
