“Today, we face the choice exactly as Friedrich Engels foresaw it a generation ago: either the triumph of imperialism and the collapse of all civilization as in ancient Rome, depopulation, desolation, degeneration – a great cemetery. Or the victory of socialism, that means the conscious active struggle of the international proletariat against imperialism and its method of war. This is a dilemma of world history, an either/or; the scales are wavering before the decision of the class-conscious proletariat. The future of civilization and humanity depends on whether or not the proletariat resolves manfully to throw its revolutionary broadsword into the scales. In this war imperialism has won. Its bloody sword of genocide has brutally tilted the scale toward the abyss of misery. The only compensation for all the misery and all the shame would be if we learn from the war how the proletariat can seize mastery of its own destiny and escape the role of the lackey to the ruling classes.”
– Rosa Luxemburg, “The Junius Pamphlet”
