Despite progress in recent years, including UN Security Council Resolution 2475 of 2019, there remains a significant gap in our awareness of the disability dynamics of armed conflict and the barriers that persons with disabilities experience in accessing the protections of international humanitarian law (IHL). This brief article will consider the protective purpose of IHL and the diversity of civilian populations, and, focussing on the principle of proportionality as an example, demonstrate how IHL must be interpreted, implemented and monitored in a manner that is inclusive and reflects the reality that civilian populations are diverse.
