Stefano Recchia (Cambridge) and Jennifer Welsh’s (Oxford) volume, Just and Unjust Military Intervention: European Thinkers from Vitoria to Mill (Cambridge: Cambridge University Press 2013), examines the question of when it’s politically, morally, and legally correct for one country to intervene in the civil war of another, and highlights how it has been a long-standing subject in history and political philosophy.
