"The provocative new book, Of War and Law ... [is] a cautionary tale of what can go wrong when military leaders and outside observers use legal language as a substitute for independent ethical thinking. According to Kennedy, the military's increasing reliance on the law creates the illusion that there is an objective way to balance civilian lives and military goals. It relieves the decider of responsibility for judgment... Kennedy traces the evolving relationship of law and warfare as the boundaries between war and peace have steadily grown less distinct."--Bill Ibelle, Harvard Law Bulletin "This powerful work by a Harvard legal scholar probes the modern transformation of warfare and the growing 'merger' of the 'professional vernaculars' of military force and law... This is an original contribution to the debate about the perils of liberal democracy in an age of limited but unending war."--G. John Ikenberry, Foreign Affairs "In this provocative and timely book, Professor David Kennedy probes the relationship between war and law, incisively unraveling two concepts that have become increasingly intertwined since the Second World War ... offering lessons for politicians and citizens alike."--Harvard Law Review "Kennedy's [book] is an innovative and provocative assessment of the contemporary uses of the laws of war. [It] makes an utterly invaluable contribution to our understanding of the role of legal ideas in regulating, constituting and debating the use of force."--Alex J. Bellamy, International Affairs "Kennedy is always an interesting thinker and writer and the themes he deals within this book are fascinating... Kennedy's points should be studied and his effort to disentangle the web of law, war and politics should be wholeheartedly supported and furthered. In this sense, Of War and Law can be viewed as an interesting contribution to a useful and intriguing debate."--Ioannis Kalpouzos, Journal of Conflict & Security Law "Kennedy's emphasis on ethics and politics is a welcome respite from the excesses of legal categories, all the more so coming from a humanitarian professional. Indeed, he wants to return the experience of responsibility to violent conflict--and to all participants. His thoughtful book is a laudable contribution in that direction."--Christian R. Donath, The European Legacy "Readers who plow through this brief book will be rewarded with unique insights concerning modern law of armed conflict (LOAC)... This is a thoughtful and intelligent hook, with a significant point. The epilogue is particularly well-done."--Gary Solis, Journal of Military History
