It is unconquerable because every blow that comes from the powers of madly raging imperialism, every new attack by the international bourgeoisie will bring new, and hitherto unaffected strata of workingmen and peasants into the fight, will educate them at the cost of the greatest sacrifice, making them hard as steel, awakening a new heroism in the masses. We know that it may take a long time before help can come from you, comrades, American Workingmen, for the development of the revolution in the different countries proceeds along various paths, with varying rapidity (how could it be otherwise!) We know full well that the outbreak of the European proletarian revolution may take many weeks to come, quickly as it is ripening in these days. We are counting on the inevitability of the international revolution. But that does not mean that we count upon its coming at some definite, nearby date. We have experienced two great revolutions in our own country, that of 1905 and that of 1917, and we know that revolutions cannot come neither at a word of command nor according to prearranged plans. We know that circumstances alone have pushed us, the proletariat of Russia, forward, that we have reached this new stage in the social life of the world not because of our superiority but because of the peculiarly reactionary character of Russia. But until the outbreak of the international revolution, revolutions in individual countries may still meet with a number of serious setbacks and overthrows. And yet we are certain that we are invincible, for if humanity will not emerge from this imperialistic massacre broken in spirit, it will triumph. Ours was the first country to break the chains of imperialistic warfare. We broke them with the greatest sacrifice, but they are broken. We stand outside of imperialistic duties and considerations, we have raised the banner of the fight for the complete overthrow of imperialism for the world. We are in a beleaguered fortress, so long as no other international socialist revolution comes to our assistance with its armies. But these armies exist, they are stronger than ours, they grow, they strive, they become more invincible the longer imperialism with its brutalities continues. Workingmen the world over are breaking with their betrayers, with their Gompers and their Scheidemanns. Inevitably labor is approaching communistic Bolshevistic tactics, is preparing for the proletarian revolution that alone is capable of preserving culture and humanity from destruction. We are invincible, for invincible is the Proletarian Revolution. The Class Struggle Devoted to International Socialism EDITED BY LOUIS C.
