The Small Arms Survey’s mission is to provide authoritative, policy – relevant information and analysis to help inform policies and programmes. The Survey’s Human Security Baseline Assessment (HSBA) project for Sudan and South Sudan benefits from a network of expert researchers and peer reviewers, and receives feedback from practitioners and others with valuable insights. In response to HSBA Issue Brief 24, Broken Promises, we received a particularly lengthy and thoughtful analysis that we believe would be useful to disseminate to a larger audience. In consultation with the author, Luuk van de Vondervoort, a former member of the UN Panel of Experts on South Sudan, we agreed to share his remarks with the wider HSBA community.
