Final answer:
The goals of the Allies in Europe were to support the USSR, attack on multiple fronts, and stop German expansion. The aim to conquer new territory was not an official objective, and the strategy to invade Japan was part of the wider campaign against the Axis but fell under a different theater of operations.
Step-by-step explanation:
The goals of the Allies in Europe during World War II were quite diverse and depended on the various phases of the war. Initially, the overall aim was to stop the aggression and expansion of Nazi Germany and its Axis partners. This included the goal to support the USSR as it faced the brunt of the German invasion after 1941, and hence, a major Allied goal was to help alleviate pressure on the Soviet Union by opening new fronts against Nazi Germany, such as the invasion of western Europe. This strategy effectively meant pursuing a policy of attacking on multiple fronts to spread thin and ultimately defeat German forces. Another important objective was to stop German expansion, which all Allies agreed upon as a fundamental necessity for peace and stability in Europe.
The goal to conquer new territory was not a stated objective of the Allies as they were keen on liberating countries under Axis control rather than acquiring land for themselves. Additionally, the plan to invade Japan was a separate strategic consideration primarily led by the United States in the Pacific Theater, although the Allies as a group were committed to defeating Japan as part of the wider Axis alliance.
