Which of the following battles is not listed among the five key battles of World War II?

The battle that is not listed among the five key battles of World War II is Normandy. While the Normandy Invasion, often referred to as D-Day, is one of the most significant operations of the war and marked the beginning of the liberation of Western Europe from Nazi occupation, it is generally considered to be part of a broader campaign rather than a standalone "key battle" in the same context as the others.

Guadalcanal, Tarawa, and Iwo Jima are all pivotal battles in the Pacific Theater, representing critical turning points in the fight against Japanese forces. Guadalcanal was the first significant offensive by Allied forces against the Empire of Japan, Tarawa was notable for its strategic location and fierce fighting, and Iwo Jima was crucial for securing airfields to support upcoming operations.

Understanding the specific roles each battle played in the overall strategic framework of World War II helps clarify their significance and why Normandy, despite its enormity, may not fit into the same classification as a key battle in the context being discussed.
