"If a war threatens to break out, it is the duty of the working classes and their parliamentary representatives in the countries involved supported by the coordinating activity of the International Socialist Bureau to exert every effort in order to prevent the outbreak of war by the means they consider most effective, which naturally vary according to the sharpening of the class struggle and the sharpening of the general political situation. In case war should break out anyway it is their duty to intervene in favor of its speedy termination and with all their powers to utilize the economic and political crisis created by the war to arouse the people and thereby to hasten the downfall of capitalist class rule."[13]
