Book excerpt: Why most modern revolutions have ended in bloodshed and failure--and what lessons they hold for today's world of growing extremism. Why have so many of the iconic revolutions of modern times ended in bloody tragedies? And what lessons can be drawn from these failures today, in a world where political extremism is on the rise and rational reform based on moderation and compromise often seems impossible to achieve? In YOU SAY YOU WANT A REVOLUTION?, Daniel Chirot examines a wide range of right- and left-wing revolutions around the world--from the late eighteenth century to today--to provide important new answers to these critical questions. A powerful account of the unintended consequences of revolutionary change, YOU SAY YOU WANT A REVOLUTION? is filled with critically important lessons for today's liberal democracies struggling with new forms of extremism."--Back cover
