In what chapter is the outbreak of world-war 1 treated?

I read some time ago The Origins of Major War by D. C. Copeland. He argues that WW1 broke out because Germany feared that due to Russia's large size, and their at the time rapid industrialisation and economic growth, would become a strategic threat in the future. Therefore Germany better had to try a war to weaken them when Germany's relative military strength was at its peak, which the German gouvernment estimated was at 1914. So, according to Copeland, the German attack on France (which they hoped to be a quick blietzkrieg as in 1871, although that failed) was primarily to clear their back for their main objective of attacking Russia.
