International Humanitarian Law and Non-State Actors: Debates, Law and Practice (Asser Press 2020). The table of contents is
here. Here's the abstract:
This book challenges the traditional approach to international law by concentrating on international humanitarian law and placing the focus beyond States: it reflects on current legal, policy and practical issues that concern non-State actors in and around situations of armed conflict.
With the emergence of the nation-State, international law was almost entirely focused on inter-State relations, thus excluding - for the most part - non-State entities. In the modern era, such a focus needs to be adjusted, in order to encompass the various types of functions and interactions that those entities perform throughout numerous international decision-making processes.
