Before becoming President, Dwight Eisenhower served in which conflict as a general?

Dwight Eisenhower served as a general during World War II, which is the correct answer. His leadership and strategic planning were crucial during significant military operations, including the Allied invasion of Normandy on D-Day. Eisenhower held the title of Supreme Commander of the Allied Expeditionary Forces in Europe, overseeing operations that led to the defeat of Nazi Germany.

In contrast, World War I occurred during Eisenhower's youth and early military career, but he was not a prominent figure during that conflict. The Korean War happened after World War II, and while Eisenhower did have military involvement in the context of policy decisions as President, he was not directly involved as a general in that conflict. The Vietnam War took place during the 1960s, long after Eisenhower’s tenure as a military leader, and he was not a general during that time. Thus, his significant military role was specifically tied to World War II, marking a foundational phase in his later political career.
