For a great short read. "Gruesome Harvest" written in 1947. A very contemporaneous description of our mistake of WWII.
Patton was killed for coming to the conclusion the USA fought on the wrong side of WWII.
Read up on Benedict Arnold as well. See what happens when an army turns on its leaders and you get the story of Benedict Arnold https://www.history.com/topics/american-revolution/benedict-arnold.
