Maja Zehfuss' book War and the politics of ethics makes the claim that Western practices of war are constituted by debates and ideas of ethics, illustrated in particular through the Western wars in Iraq and Afghanistan. Herein, this claim is assessed by drawing on Tarak Barkawi and Shane Brightons argument that in contemporary research, war tends to be conceived through secondary phenomena. The paper argues that research focusing on how war is shaped by secondary phenomena often falls back on a reductive understanding, in which war is represented as violent destruction. Moreover, that by seeing war as a multifaceted form shaped by military imaginaries centring on military theory, tactics, and operational art, we may gain a more comprehensive understanding of its ontology and practices.
