Being Supreme Allied Commander in Europe during WWII helped.

Eisenhower had been a general, leading the Allied Expeditionary Force in Europe during World War II and he led the D-Day invasion in 1944.

Any of the 1000s of Eisenhower biographies, including one I am sure you could find on Wikipedia, would give you this. The fact that you even ask this question shows a stunning lack of history being taught in schools.

He was a general who had command of the troops. He also worked his way up and fought in WW2 so he has experience.
