How the Russian Revolution and the entry of the US affected the course and outcome of the war?

Answer 1

During World War I, the entry of America into the war and the outbreak of the Bolshevik (or, Russian) Revolution, both occurring in 1917, had important effects upon the final outcome of the war. The Revolution knocked Russia out of the war, which led to Germany's ability to bring even more force to bear on the Western Front in a mighty offensive in 1918. The presence of American troops on the battlefield in 1918 proved too much, however. Along with American energy and supplies, these troops were decisive in the ultimate victory of the Alliance.

Answer 2

Nothing.

The US entry into World War I was contemporaneous (at the same time) as the Russian Revolution but the the two events were not influenced by each other. The Russian Revolution led to the Russian withdrawal from World War I and meant that the Second Reich (Germany) could move a much larger share of its military to the Western Front. If the US had not joined the war at this point, the Germans would likely have overwhelmed the French and the British.
