How did the location of the axis powers in europe contribute to their defeat

Germany and Italy are located in the middle of the battle ground, which make them surrounded by the allied forces

Explanation:

At that time, both Germany and Italy were surrounded on the western front by United Kingdom and France. They had to face Soviet union's large army on the eastern front and united states keep pressuring them from the north. This make it really hard for the axist power to focus the troops for their defense which eventually led to their downfall.
