Dwight Eisenhower
Dwight Eisenhower was very underrated in the sense of legacy as President. As a five-star General in World War II, Eisenhower knew the dangers of war. Not only of war itself, but all of the other factors involved with war such as foreign policy. In his farewell address, he coined a term the "military-industrial complex." In the context he was using it in, he wanted to maintain a strong defense but he did not want to have a formidable union between the armed forces and defense contractors. He reason was due to the increased burden on the taxpayers due to excessive military spending. Unfortunately, America has not learned its lesson today.
