How did the russian revolution impact world war i?

Russian Revolution was a turning point in the history of Russia. Russia was ridden with war crises and food scarcity. Bolsheviks had successfully controlled Russia in 1917 and promised bread, peace, and land. They started the negotiations but with little success. The internal dispute in Russia divided Russians and weakens the eastern front. Peace negotiation with Germany has supplied more resources to the western front. It seemed allied powers would lose but the U.S entry in war has changed the situation.
