This chapter considers the worst contemporary state-led prosecution of a minority group, which amounts to genocide, namely the Rohingya. It examines the atrocity crimes committed against them under international criminal law (ICL) and the application of Responsibility to Protect (R2P) thereupon. It suggests that such atrocities are constitutive of violations of jus cogens which warrants obligatio erga omnes. Accordingly, the perpetrators can be brought to justice under inter/national and universal jurisdictions, which, nonetheless, has not yet occurred. Given the failure of ICL mechanisms, the normative foundations of the R2P can provide valuable tools for intercepting mass atrocity crimes. The Rohingya—who face direct and structural violence at the hands of the Myanmar state—need protection from these crimes. The chapter explains how insular national politics can undo the gains made by the international community in upholding the distinctiveness of humanitarian claims through the application of the R2P.
