This book hits the problems with American History texts on the nose. Finally a book that explains the rest of the story. I always wondered where the animosity between the Soviet Union and the US came from. I collect old newspapers and books and never found anything from period papers that said "states rights" had anything whatsoever to do with the Civil War, the issue was Slavery... Period! I am a little mystified at how some of the readers from outside the US can condemn this book, since I doubt they ever read our old textbooks. This book is excellent and essential for every student of American History.
