Promoting restraint among non-state armed groups often requires more than legal appeals—it demands engagement strategies that resonate with the groups’ own goals and concerns. This post outlines five pragmatic approaches to operationalize non-humanitarian drivers of restraint, including engaging legitimacy-givers, facilitating peer learning, highlighting long-term consequences, offering practical training, and supporting internal political education. While some strategies may lie beyond the scope of traditional humanitarian diplomacy, they offer valuable entry points for building trust and encouraging more humane conduct in armed conflict.
