Unknown Secrets of World War II

I am writing this book because I want to discuss a piece of American/World History about World War II that no one has thoroughly examined.
I am not a historical revisionist, nor am I a member of the American right-wing. I am neither a supporter in no shape or form of fascist ideology either. I just want to take a closer look at a piece of World War II history that has not been looked at very much by mainstream historians.
