What war was President Eisenhower a general in?

President Eisenhower served as a general during World War II, where he played a significant role as the Supreme Commander of the Allied Expeditionary Forces in Europe. His leadership was crucial in planning and executing major operations, including the D-Day invasion of Normandy in 1944, which was pivotal in the defeat of Nazi Germany.

The Civil War occurred long before Eisenhower's time, and he had no military involvement in World War I, although he did serve in the army during that time in various capacities, he was not a general. The Korean War occurred after World War II, and while Eisenhower was President during this conflict, he was not involved as a general. Thus, the correct answer is that his notable role as a general was during World War II, which significantly shaped his future political career and laid the foundation for his presidency.
