Answer:
Allied nations wanted to diminish Germany’s economic and military power.
Step-by-step explanation:
The allied nations, some of which included the United States, France, and the Great Britain, who proved victorious after World War 1 implemented several punishments against the Germans and one of these was the loss of their acquired territories. Their main reason for doing this was to diminish Germany's economic and military power.
Rhineland was demilitarized, Alsace-Lorraine was returned to France, Denmark got back Northern Schleswig, amidst several other losses. Germany found these punishments humiliating and proceeded to plan for a second world war.
