Before he became President, which war did Eisenhower serve as a general in?

Eisenhower served as a general during World War II, which is recognized as a crucial period in military history characterized by significant global conflict from 1939 to 1945. During the war, he was appointed as the Supreme Commander of the Allied Expeditionary Forces in Europe and played a pivotal role in orchestrating major operations, including the D-Day invasion of Normandy in 1944. This leadership was instrumental in planning and executing military strategies that ultimately led to the defeat of Nazi Germany. His extensive experience and successful leadership during World War II greatly contributed to his rise in political stature and later success as President of the United States.

The other wars listed did not involve Eisenhower in a general's capacity prior to his presidency. World War I took place before his rise to prominence in the military. The Korean War and the Vietnam War occurred after World War II, during which Eisenhower was serving as President, rather than as a general.
