It has become common to criticise just war theory (and just war theorists) for being overly abstract, and thus for offering little practical guidance to citizens, politicians, and combatants. That is not a criticism one can level at Finlay's book. On the contrary, his rich and illuminating account of the conditions under which war is just - or at least less unjust than not fighting at all, or fighting without restraint - is anchored in a nuanced and sensitive awareness of the moral and political realities of warfare. Cecile Fabre, All Souls College, Oxford This book is an excellent primer on contemporary just war debates. Well written, cogently explained and up-to-date, its argument is compelling and it will be a must read for all students of just war theory. Alex Bellamy, The University of Queensland
