Which of the following events did NOT occur during World War II?

The Vietnam War did not occur during World War II; it took place later, mainly from the late 1950s through the fall of Saigon in 1975. This conflict involved the United States, its allies, and North Vietnam, as well as the Viet Cong. In contrast, the other events mentioned—such as the Battle of the Bulge, the Battle of Midway, and the storming of Normandy—were significant military operations that occurred during World War II, which lasted from 1939 to 1945. Each of these battles played a crucial role in shaping the outcome of the war, with the Battle of Midway being a pivotal naval engagement in the Pacific, the storming of Normandy marking the beginning of the liberation of Western Europe from Nazi control, and the Battle of the Bulge serving as the last major German offensive on the Western Front.
