How did geography affect the course of World War 2?

Geography influenced World War 2 by shaping military strategies and operations. For example, the vastness of the Soviet Union provided space for the Red Army to retreat and regroup against German forces. Similarly, the English Channel acted as a natural barrier that helped protect Britain from invasion by Nazi Germany. Geography also influenced the outcome of battles, such as the harsh winter in Russia which played a significant role in halting German advances.
