Trotsky blamed the peace treaty on the bourgeoisie, the social revolutionaries, Tsarist diplomats, Tsarist bureaucrats, "the Kerenskys, Tseretelis and Chernovs", the Tsarist regime, and the "petty-bourgeois compromisers". The treaty opened a permanent rift between the Bolsheviks and Left Socialist Revolutionaries. In July 1918 the Left SRs assassinated German Ambassador Wilhelm von Mirbach in the hopes that it would induce Germany to annul the treaty, leading to the Left SR Uprising. Relations between Russia and the Central Powers did not go smoothly. The Ottoman Empire broke the treaty by invading the newly created First Republic of Armenia in May 1918.

However, relations between Russia and the Allied Powers were also bad due to the Allied Powers' intervention in the Russian Civil War against the Soviet government of Russia and its allies. The fate of the region, and the location of the eventual western border of the Soviet Union, was settled in violent and chaotic struggles over the course of the next three and a half years. The Polish–Soviet War was particularly bitter; it ended with the Treaty of Riga in 1921. Although most of Ukraine and Belarus fell under Bolshevik control and eventually became two of the constituent republics of the Soviet Union, Poland and the Baltic states re-emerged as independent nations. In the Treaty of Rapallo, concluded in April 1922, Germany accepted the Treaty's nullification, and the two powers agreed to abandon all war-related territorial and financial claims against each other.
