Protection by process : implementing the principle of proportionality in contemporary armed conflicts
The grey zone : civilian protection between human rights and the laws of war
Oxford [etc.] : Hart, 2018
Taking the example of the US presidential policy guidance on targeted killings, this chapter looks at current changes in the understanding and implementation of the principle of proportionality in international humanitarian law. The author notes that scholars believe that the growing intolerance for any civilian casualties reflects a profound change in the legal norms applicable to armed conflicts. He argues that this evolution stems from the bureaucratisation of military operations and the penetration of new societal attitudes to civilian casualties to the military sphere.
