Before he was President, Dwight D. Eisenhower served as a general in which war?

Dwight D. Eisenhower served as a general during World War II, where he held significant leadership positions, including serving as the Supreme Commander of the Allied Expeditionary Forces in Europe. He played a pivotal role in planning and executing major operations, including the D-Day invasion of Normandy in 1944, which was crucial to the Allied victory in Europe.

While Eisenhower did have military experience prior to World War II, particularly during World War I, it was not as prominent or influential as his role in World War II. He did not serve in the Korean or Vietnam Wars, which took place after World War II and were not part of his military career. Thus, his most notable military service, which shaped his reputation and contributed to his later political career, occurred during World War II.
