“An International does not mean sitting at the same table and having hypocritical and pettifogging resolutions written by people who think that genuine internationalism consists in German socialists justifying the German bourgeoisie’s call to shoot down French workers, and in French socialists justifying the French bourgeoisie’s call to shoot down German workers in the name of the ‘defence of the fatherland!’ The International consists in the coming together (first ideologically, then in due time organisationally as well) of people who, in these grave days, are capable of defending socialist internationalism in deed, i.e., of mustering their forces and ‘being the next to shoot’ at the governments and the ruling classes of their own respective ‘fatherlands.’ This is no easy task; it calls for much preparation and great sacrifices and will be accompanied by reverses. However, for the very reason that it, is no easy task, it must be accomplished only together with those who wish to perform it and are not afraid of a complete break with the chauvinists and with the defenders of social-chauvinism.”
