I would like to respectfully recommend "War is a Racket" by the most decorated soldier in U.S. History, Marine Brigadier General Smedley D. Butler. Quote from the Front Cover. "I spent 33 years in the Marines, most of my time being a high-class muscle man for big business, for Wall Street and the bankers. In short, i was a Racketeer for Capitalism." - SDB. It's a pretty bi-partisian book, written in 1935 by General Butler and still quite readable at 66 pages. It includes a later essay entitiled "Common Sense Neutrality"
