Ms. Nusse does a professional job of explaining Hamas' ideology, particularly as regards its opposition to the Arab-Israeli peace process. She does a great job of explaining how their understanding of Islam and the Qur'an lead them to the positions they take. She does an equally good job of showing where they deviate from the Qur'an when they find it politically expedient to do so. After finishing the book, I feel that I actually have a decent understanding of Hamas and why it thinks and acts as it does. I have only two critcisms: 1) Ms. Nusse sometimes does a poor job making clear whether she is giving her own personal opinion on an issue, or merely explaining Hamas'; and 2) the editor is to be faulted for allowing far too many spelling and grammar errors. I can't blame Ms. Nusse for that, she's not a native English speaker.
