Though there are plenty of caveats and exceptions, it is safe to generalize that predictions of what the “next war” was going to be like before 1914 were completely inaccurate. The Great War would not be the quick, clean affair typical of the wars of German unification in the 1860’s-70’s or the sensationalist literature of the antebellum period. The generals were as wrong as the general public and war nerds. France had an irrationally fervent belief in the power of the offensive and dreamed of the Russians steam-rolling over Berlin before winter, while the Germans gambled their victory on the success of the Schlieffen plan. When the war finally came, the linear tactics of previous wars floundered in the machine guns, artillery, mud, and barbed wire of trench warfare. The belligerent societies were placed under so much strain by this first industrial total war that by its end, four great monarchies would vanish off the face of Europe.
Nonetheless, there were three theorists – a Communist, a Warsaw banker, and a Russian conservative minister – who did predict the future with a remarkable, even eerie, prescience. They were Friedrich Engels, Ivan Bloch, and Pyotr Durnovo.
