Abstract This article examines how atrocity prevention efforts have had a limited effect on the violence and atrocities being committed in Myanmar. Myanmar’s military forces, the Tatmadaw, remain free to commit atrocities against vulnerable populations in the country, particularly against the Rohingya minority in Rakhine state. These efforts have been stymied at both the international and regional levels, especially now that the Tatmadaw rule the country following a coup d’etat in February 2021. UN efforts have fallen short as the Tatmadaw refuse to cooperate with the international community due to a lack of trust in UN processes and a subsequent siege mentality over heightened international outrage over the treatment of both the Rohingyas and protesters against the coup. Prevention efforts through asean, of which Myanmar is a member, have also fallen short. This is due primarily to a lack of accountability for erring members, and a long-standing principle of non-interference in members’ domestic affairs. Currently, there are no incentives for the Tatmadaw to negotiate and stop the violence committed against their own people. Indeed, the failure of these prevention efforts and the increased notions of nationalism they foster may be used by the Tatmadaw to continue their current policies of isolation and maintain power.
