I did not claim that either you or I had read every book in the world. I just don't understand how you dismiss this book in the way that you have if you don't know the author and haven't read the book or even more than one review of it.
I suppose if it threatens your world view, you might want to avoid it.
I've studied WW2 history for 40 years and don't feel I have to read every revisionist book by every pop historian.
