War Is a Racket by Smedley Butler (1881 - 1940)

Marine Maj. Gen. Smedley Butler's expose of American Corporate Imperialism. Butler said, “I served in all commissioned ranks from second lieutenant to Major General. And during that period I spent most of my time being a high-class muscle man for Big Business, for Wall Street, and for the bankers. In short, I was a racketeer for capitalism. I suspected I was just part of the racket all the time. Now I am sure of it.” - Summary by John Greenman and https://www.americanswhotellthetruth.org/portraits/major-general-smedley-butler
