What are the current threats to international humanitarian law compliance?

Loren Voss, Public Service Fellow at Lawfare, sits down with Stuart Casey-Maslen, the head of the IHL in Focus project at the Geneva Academy of International Humanitarian Law and Human Rights. They discuss the Geneva Academy's “IHL in Focus Report” covering all the major armed conflicts around the world, the role of new technology such as drones, the threats to IHL compliance and accountability, and the possibility of new treaty rules.

Casey-Maslen describes the 20+ year degradation of IHL and trends across conflicts, particularly regarding the use of advanced technology. He laments that while technology allows for the possibility of more precise targeting of valid targets, the realities on the ground don't always reflect that. Voss and Casey-Maslen discuss challenges to enforcement and accountability, but Casey-Maslen remains optimistic that protection of civilians in armed conflict can get better in the future.
