Final answer:
World War I had a different impact on Russia compared to Western European countries. Russia faced military difficulties, the downfall of the tsarist regime, and the spark of the Russian Revolution, while Western European countries faced different challenges.
Step-by-step explanation:
The impact of World War I on Russia was different from its impact on Western European countries. In Russia, the war exacerbated existing issues and led to the downfall of the tsarist regime, ultimately sparking the Russian Revolution. The Russian army faced significant difficulties, with incompetent commanders, a lack of supplies, and low morale.
Additionally, Russia's inadequate industrial base and lack of infrastructure hindered its military efforts. There were also various diplomatic and economic dilemmas with other countries during this time period. In contrast, Western European countries faced different challenges and did not experience a revolution as a result of the war.
