Hi Sunspot,
You may b interested in a new book being published right now regarding Hitler and the Watchtower. It is by Dr. James Penton. He wrote the book, "Apocolypse Depayed," a very honest and detailed history of Jehovah's Witnesses. It is a must read and highly complements Ray Franz's books.
Jim Penton is a former JW ... and a professor of History at the University of Toronto, Canada. He is now retired ... but has written a number of books. You can be sure that his treatment of the JWs will be honest, fair, and balanced ... but, it is a book that I think many ex-JWs should read.
Jim W.
