Final answer:
The Allies required Germany to give up most of their weapons, including planes and submarines, to prevent future aggression by limiting Germany's military capacity and to maintain peace in Europe after the World Wars. Disarmament was enforced through the Treaty of Versailles after WWI and through strategic military actions during WWII.
Step-by-step explanation:
After the devastation of World War I and World War II, the Allies required Germany to disarm to prevent future aggression by limiting its military capacity. The Treaty of Versailles imposed strict limitations on the German military, restricting the number of soldiers, and limiting the production of heavy equipment, warships, submarines, airplanes, and other military assets.
Similarly, during World War II, German military equipment, including planes and U-boats, were targeted and destroyed by the Allies to mitigate submarine attacks and aerial bombings that were part of Germany’s warfare strategies.
The utilization of advanced technology, such as radar and sonar, by the Allied forces effectively countered the German U-boats, while strategic bombings of German cities aimed to disrupt war production and morale.
With these measures, the Allies hoped to reduce Germany's capacity to wage war in the future and maintain peace in Europe. Additionally, previous aggression shown by Germany through submarine warfare and blitzkrieg tactics necessitated the disarmament measures to prevent similar future conflicts.
