Why were many western nations against the October Revolution?

Answer 1

The western nations feared that after the October Revolution, Lenin and the Bolsheviks would get Russia out of World War I. The Tsar and even the Provisional Government after the Tsar abdicated wanted Russia in the war to fight Germany and the others of the Central Powers. The Bolsheviks had promised to end the war and the western nations fighting Germany were afraid Lenin would take Russia out of the war as he had promised many times. Germany smuggled Lenin into Russia just so he could cause revolutionary problems to disrupt the Russian war machine. After the October Revolution Lenin did just that, signing the Treaty of Brest-Litovsk and making peace with the Central Powers. Now Germany could concentrate all it's troops on the West-front and was not caught in a two-front-war any more.
