"''5.With reference to the bourgeois and chauvinist sophisms being used by the bourgeois parties and the governments of the two chief rival nations of the Continent—the German and the French—to fool the masses most effectively, and being copied by both the overt and covert socialist opportunists, who are slavishly following in the wake of the bourgeoisie, one must particularly note and brand the following:

When the German bourgeois refer to the defence of the fatherland and to the struggle against tsarism, and insist on the freedom of cultural and national development, they are lying, because it has always been the policy of Prussian Junkerdom, headed by Wilhelm II, and the big bourgeoisie of Germany, to defend the tsarist monarchy; whatever the outcome of the war, they are sure to try to bolster it. They are lying because, in actual fact, the Austrian bourgeoisie have launched a robber campaign against Serbia, and the German bourgeoisie are oppressing Danes, Poles, and Frenchmen (in Alsace-Lorraine); they are waging a war of aggression against Belgium and France so as to loot the richer and freer countries; they have organised an offensive at a moment which seemed best for the use of the latest improvements in military matériel, and on the eve of the introduction of the so-called big military programme in Russia.

Similarly, when the French bourgeois refer to the defence of the fatherland, etc., they are lying, because in actual fact they are defending countries that are backward in capitalist technology and are developing more slowly, and because they spend thousands of millions to hire Russian tsarism’s Black-Hundred[4] gangs for a war of aggression, i.e., the looting of Austrian and German lands.

Neither of the two belligerent groups of nations is second to the other in cruelty and atrocities in warfare.''
