The Conclusion draws on the findings of the book to analyse the main implications of a reciprocity-based understanding of belligerent reprisals. First, it distinguishes this formalization of belligerent reprisals from earlier theories stressing the law-making function of the measure. Then, it accounts for the continued relevance of belligerent reprisals even at a time when mechanisms monitoring and enforcing compliance with the laws of armed conflict gain momentum. Finally, it explains how a reciprocity-based interpretation of belligerent reprisals would affect follow-up reform of the mechanism – be it in the sense of fine-tuning its regulation, or in the sense of disposing of it altogether.
