"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."
