Existing studies on the Myanmar-Rohingyan crisis have explored the contending issues from a narrow perspective. This underscores the need for broader engagement by interrogating the veracity of the claims of mass atrocities against the Rohingyans, nonauthorization of the Responsibility to Protect (RtoP), and implications for consolidating and internalizing the RtoP norm. This study argues that, while the acts of genocide, crimes against humanity, war crimes, and ethnic cleansing against the Rohingyans satisfies four of the crimes upon which RtoP can be authorized, its nonauthorization suggests that in spite of its commitment to “Never Again,” the international community is yet to come to terms with issues bordering on mass atrocity and civilian protection. This inaction amidst widespread atrocities against the Rohingyans explains why the RtoP is not only contested, but also risks the chances of further nonutilization and institutionalization. Thus, the possibility that the RtoP would remain valuable depends on how the international criminal court and the global community prosecute those culpable of atrocities against the Rohingyans, adopt a clear rule of establishing when mass atrocity has been perpetuated and demand RtoP intervention, and ensure that these interventions are guided by the principle of Jus in Bellum and Jus ad Bello.
