America is at war with terrorism. Terrorists must be brought to justice. We hear these phrases together so often that we rarely pause to reflect on the dramatic differences between the demands of war and the demands of justice, differences so deep that the pursuit of one often comes at the expense of the other. In this book, one of the country's most important legal thinkers brings much-needed clarity to the still unfolding debates about how to pursue war and justice in the age of terrorism. George Fletcher combines insights from history, philosophy, literature, and law to place these debates in a rich cultural context. He seeks to explain why Americans, for so many years cynical about war, have recently found war so appealing. He finds the answer in a revival of Romanticism, a growing desire in the post-Vietnam era to identify with grand causes and to put nations at the centre of ideas about glory and guilt. Fletcher opens with unsettling questions about the nature of terrorism, war, and justice, showing how dangerously slippery the concepts can be. He argues that ideas about collective glory and guilt are far more plausible and widespread than liberal individualists typically recognise. But as he traces the implications of the Romantic mindset for debates about war crimes, treason, military tribunals, and genocide, he also shows that losing oneself in a grand cause can all too easily lead to moral catastrophe.
