Though the Bolsheviks suppressed syndicalism in Russia, they courted syndicalists abroad as part of their international strategy. In March 1919, the Comintern or Third International was founded at a conference in Moscow. The Bolsheviks acknowledged syndicalism's opposition to socialist reformism and saw them as part of the revolutionary wing of the labor movement. No syndicalists attended the founding convention, mainly because the blockade of Russia by the Allies powers made travel to Moscow near impossible. After long discussions, the CNT opted to join the Comintern, though it classified its adherence as provisional as a concession to detractors of Bolshevism. USI also decided to join, though some like Borghi had reservations about the course of events in Russia. In France, the CGT's radical minority that had opposed the war enthusiastically supported Bolshevism. They formed the Revolutionary Syndicalist Committees and attempted to push the CGT as a whole to support the Comintern. The General Executive Board of the IWW decided join the Comintern, but this decision was never confirmed by a convention. German and Swedish syndicalists were more critical of Bolshevism from the start. Rocker declared already in August 1918 that the Bolshevik regime was "but a new system of tyranny".
