Like all anthologies, this is a bit of a mixed bag, but overall it is strong. Even the weaker peices are OK. Some of the essays are just summaries of the history of nonviolent action in some geographical region. Sort of interesting, but I found those pieces to have too much information crammed into too little space. Fortunately, most of the articles are case studies of particular nonviolent campaigns or movements. Some of them are simply narratives--it's not clear what lessons are to be drawn. Most of these case studies analyze the movement or campaign in question in such a way that activists can draw some valuable lessons from them, although in some cases the lessons are left implicit instead of being spelled out, which is kind of annoying. These lessons include both ideas on the application of nonviolent tactics and examinations about how these tactics have diffused from one group or region to another. Finally, there are a few more theoretical pieces, including the conclusion by Zunes and Kurtz, which I thought was the best thing in the book. They critique much nonviolent theory as being overly voluntarist--focusing too much on what social activists do and not enough on how the social and political contexts they are operating create different opportunities and constraints. Zunes and Kurtz argue for a balanced approach that analyzes systems of power and tries to understand how nonviolent activists can best put pressure on them, which is going to differ immensely depending on the larger context. Zunes and Kurtz also examine why nonviolent tactics have increasingly come to be favored over armed struggle--but also the ways in which nonviolent activists have needed to continually innovate as governments have gotten wise and adopted effective means of diffusing the power of nonviolent activism (means that range from making it easy to get permits for marches to paramilitary death squads, depending on geographical region). Overall, this is a valuable source of information on nonviolent movements, what has worked and what hasn't.
