Was president eisenhower’s warning about the industrial military complex meaningful or, is there a more significant concern (e. g., the threat of terrorism or nuclear proliferation) that requires an ever-present strong military readiness?

The Eisenhower's Farewell Adress was meaningful.

Explanation:

The reason why this speech was so important and had a meaningful message, was because it showed how the ambition to build a complex military force has led the nation to invest a lot of resources to a cause that has some grave implications, like losing liberties and democratic processes, or forgetting about the peaceful methods and goals. Don't let the power and strenght carry the nation in the wrong direction.
