Final answer:
The Allied strategy for victory over the Axis Powers in Europe included successful campaigns against Rommel in Africa, Russia's crucial battles against Germany, and the crucial invasion of Normandy (D-Day). Additionally, technology, conferences like Yalta, and broader strategies like Europe First contributed to the Allied victory. The Pacific Theater's Island-Hopping strategy and use of atomic bombs on Japan were also key to ending the war.
Step-by-step explanation:
The strategy for Allied victory in Europe after the U.S. entered World War II encompasses several key operations and fronts. These include a) Allies' strategy against Rommel in Africa, which was critical in reversing Axis gains in North Africa and involved American troops landing in French Morocco and pushing Axis forces into Tunisia with the collaboration of British forces. b) Russia's strategy against Germany, effectively turning the tide of battle in Eastern Europe, was another crucial aspect of the overall victory plan. Lastly, c) The invasion of Normandy, known as D-Day, was a pivotal moment marking the beginning of the end for the Axis Powers in Europe. Each of these topics is interconnected and essential to understanding the combined efforts that led to the downfall of the Axis Powers in the European Theatre.
Additional factors influencing victory included the collaboration of the Big Three at conferences like Yalta, the adoption of a Europe First strategy, and the fact that operations such as Operation Torch in North Africa served as a springboard for later campaigns.
Within the broader context, the Pacific Theater also played a significant role, where strategies such as the "Island-Hopping" campaign and the use of atomic bombs on Hiroshima and Nagasaki led to the eventual surrender of Japan. The use of technology, such as aircraft carriers, and securing airfields were pivotal in these operations.
