Why did Russia’s withdrawal from the war hurt the allies?

Answer 1

Russia's withdrawal from the war hurt the allies because it removed a major military force from the Allied side. This weakened the Allied forces and allowed the Central Powers to gain an advantage in the war. Additionally, Russia's withdrawal meant that the Allies had to divert resources to the Eastern Front, which weakened their forces on the Western Front. This allowed the Central Powers to gain ground and eventually win the war.
