In what way might the Allies benefit from Germany's decision to fight on two fronts? O Germany would have to face the vastly larger and more powerful Russian army on its eastern front.
O The Allies might attack Germany on the French side because the Germans had no troops at that border.
O The Allies would be fighting on familiar mountainous territory, which the Germans weren't used to.
O Germany would become weaker by having to divide its military resources between the fronts.
