This position by the Leninists of the necessity for a dictatorship to protect the revolution was not proven in the Civil War which followed the Russian revolution; in fact without support of the Anarchists and other left-wing forces, along with the Russian people, the Bolshevik government would have been defeated. And then true to any dictatorship, it turned around and wiped out the Russian and Ukrainian Anarchist movements, along with their left-wing opponents like the and Social revolutionaries. Even ideological opponents in the Bolshevik party were imprisoned and put to death.

Aware that to establish a solid political base and carry out his revolutionary program he needed time, in March 1918 Lenin had his lieutenants sign at Brest-Litovsk a highly unpopular peace treaty with the Germans, Austrians, Turks, and Bulgarians in which he surrendered vast territories. And he unleashed a civil war in Russia as a prelude to the worldwide revolution, his ultimate objective. The Bolsheviks subsequently liked to blame the civil war that ravaged Russia for three years, claiming millions of lives, on Russian reactionaries and their foreign supporters. But, as we have noted, the transformation of the war from a conflict between nations to one between classes had been a central plank in the Bolshevik platform long before 1917. Trotsky admitted that much when he wrote, “Soviet authority is organized civil war.” In fact, it may be said that the Bolsheviks seized power in Russia in order to make civil war.

Nevertheless, from November 1918 onwards the tide of the civil war ran the Bolsheviks' way. By April 1919 Kolchak's forces had been beaten and by July Perm was back in Bolshevik hands, followed by Omsk itself in November. Denikin enjoyed some success in the Ukraine in the summer of 1919 but had lost Kiev by the end of the year. Yudenich's attempt to capture Petrograd had also failed, thanks in large measure to Trotsky's rallying of the city's defenders, who drove the defeated White army back into Estonia, whence they had come. General Peter Wràngel's Caucasian Army had captured Tsaritsyn that June, but by January 1920 it was clear that the war was effectively over. The Allies cut off their aid to the Whites. One by one the generals fled or, like Kolchak, were captured and executed. By the summer of 1920 Lenin felt confident enough to export the Revolution westwards, ordering the Red Army to march on Warsaw and confidently talking of the need to 'sovietize Hungary and perhaps Czechia and Romania too'. Only their decisive defeat by the Polish army on the banks of the River Vistula halted the spread of the Bolshevik epidemic.
