Recently finished 'Young Stalin'. Very interesting as I had no idea about the guy before I started. He was a gangster and bank robber for a good spell. He also impregnated a 13 year old girl and then abandoned her. The more I read about world leaders the more I realize that they were simply the biggest and most successful thugs of their time.
Also finishing up Freethinkers, about American secularism. It's interesting to note the absolute denial of American history that predicate so many of the modern religious right's arguments. To a large degree, they've rewritten America's past and the separation of church and state. Not many people are looking closely is the main reason. I guess it just sounds good to some people to say this is a 'Christian Nation' and dump the 18th and 19th century.
Just started a bio on Ahmadinejad.
