In "A Short History of World War II," James L. Stokesbury discusses the significant impact of a united Germany on the balance of power in Europe. He emphasizes that, despite various treaties aiming to maintain peace, the underlying reality remained that Germany had the potential to become the most formidable force on the continent. This understanding reshaped the geopolitical landscape as nations adjusted their military strategies in response to the growing strength of Germany.

Particularly, France recognized the threat posed by a united Germany and began to rearm in preparation for possible future conflicts. This action indicates the heightened tensions and the urgency with which countries approached their defense strategies during this pivotal era. The rearmament efforts by France highlight the pervasive fear and anticipation of another major war in Europe stemming from the rise of German power.
