This book, like most of what the ISO/SWP publishes, is a well-researched, clearly written account. The book looks at 5 working class uprisings since the late 60s, drawing stirring and vivid pictures of the solidarity, initiative, and courage people are capable of when the time comes to fight for freedom. I was particularly interested in the account of the Chilean cordones, worker-peasant coalitions, and the impressive achievements of Polish Solidarity even under a highly authoritarian regime. And the story Iranian Revolution gives the lie to the simplistic demonization of Iranians in the present political climate, drawing a fascinating and complex picture of the intersections of class- and religious-based struggle.
The book is ultimately a cautionary tale against the betrayal by reformists who time and again try to keep a lid on the revolutionary impulse and channel mass struggle into the killing fields of bourgeois party politics.
The authors harp over and over, though, on a more suspect lesson, the one they claim is the most pressing: the need for a vanguard party to lead the workers in their struggles. I look at ISO/SWP Trotskyist literature much the same way as the Wall Street Journal: learn from the carefuly researched factual accounts, and through the editorials in the dustbin.
For a non-vanguardist account of Paris '68, the essays Murray Bookchin's terrifiic "Post-Scarcity Anarchism" are well worth reading. Also, I have heard that Loren Goldner's book on Portugal is excellent, presenting the events from a left-communist perspective.
