This book is full of detailed analysis, though things have changed immensely since it was written (2000), so you are best served by reading its more recent edition. It makes important points, debunking the popular view of Hamas as a rigid organization--while rigid in its views, the organization has had to rely upon adaptability and compromise with the PLO (and hence, indirectly, with Israel) while under PLO leadership. While under PLO domination, Hamas (for the most part) painstakingly avoided confrontation with other Palestinian factions, a principle so important it is decreed at length in the Hamas charter and was constantly reiterated in the faction's propaganda. It is interesting how quickly this fundamental precept has been gruesomely abandoned following Hamas' rise to power. The book also addresses the rift between the organization's "inside" and "outside" leadership, the latter tending to be more radical because it doesn't face the daily realities of occupation. Finally, it emphasizes the fact that Hamas owes most of its popularity to its vast charity work rather than its ideology. One of the most interesting parts is the book's inclusion of the full text Hamas charter, which is striking in its blatant anti-Semitism, extolling the virtues of killing "Jews" (as opposed to just "Zionists") and making frequent reference to wild conspiracy theories and the Protocols of the Elders of Zion. While well-researched, the book is written in a dry, academic style, so I would recommend it for people who already have an academic background in the subject rather than those looking for a basic introduction.
