A two-front war was the nightmare of German strategists, who surely learned the lesson from the First World War.
In the first place, having to fight on two fronts puts a contender in an absolute strategic disadvantage, because you have to divide your forces, your might, to face a coalition of enemies. You can´t deliver a smashing blow to your enemies in one place because your might is divided. You see?
Secondly, a two-front war imposes on you difficult dilemmas regarding where to allocate your limited resources or where to send reinforcements, because sending , let´s say, 200,000 more soldiers to one front makes it impossible to use them on the other front.
