And, finally, the only war left for Prussia-Germany to wage will be a world war, a world war, moreover of an extent the violence hitherto unimagined. Eight to ten million soldiers will be at each other s throats and in the process they will strip Europe barer than a swarm of locusts. The depredations of the Thirty Years War compressed into three to four years and extended over the entire continent; famine, disease, the universal lapse into barbarism, both of the armies and the people, in the wake of acute misery irretrievable dislocation of our artificial system of trade, industry and credit, ending in universal bankruptcy collapse of the old states and their conventional political wisdom to the point where crowns will roll into the gutters by the dozen, and no one will be around to pick them up; the absolute impossibility of foreseeing how it will all end and who will emerge as victor from the battle. Only one consequence is absolutely certain: universal exhaustion and the creation of the conditions for the ultimate victory of the working class. That is the prospect for the moment when the development of mutual one-upmanship in armaments reaches us, climax and finally brings forth its inevitable fruits. This is the pass, my worthy princes and statesmen, to which you in your wisdom have brought our ancient Europe. And when no alternative is left to you but to strike up the last dance of war that will be no skin off our noses. The war may push us into the background for a while, it may wrest many a conquered base from our hands. But once you have unleashed the forces you will be unable to restrain, things can take their course: by the end of the tragedy you will be ruined and the victory of the proletariat will either been achieved or else inevitable.
