I've read an advance copy of They Knew They Were Right, Jacob Heilbrunn's upcoming history of neoconservatism. Heilbrunn is more or less a former neocon, seeing the movement as having been crucially correct about the Soviet threat in the 1970s but wrong on Iraq and much else in more recent times. It's worth a read, but I don't expect many minds to be changed by it. If you love neocons, you likely will continue to do so after reading this book. If you hate them, ditto.
