In recent years, there has been an upsurge in the number of civilian resistance movements (CRMs) within states to counter government repression and coups d’états through which civilians are on the frontlines of state brutality and mass atrocities. This article considers the implications of CRMs for atrocity prevention and the associated responsibility to protect norm by asking, Should the international community support CRMs as part of its wider commitment to ending mass atrocities? In this article, we evaluate both military and nonmilitary support to CRMs. We argue that in the context of coups and government repression, providing lethal military support to CRMs will often make things worse in terms of atrocity prevention. We however explain that the provision by the international community of nonlethal and nonmilitary support through political recognition, technical assistance, and accountability can yield positive results. We illustrate this argument with the case of Myanmar.
