ABSTRACT
The convergence between responsibility to protect, treaty obligations and obligations erga omnes may be relevant in situations like the current fight against the Islamic State, not only in relation to genocide but also with regard to different atrocities. Other obligations erga omnes are at the basis of the responsibility to protect and, at the same time, embodied in conventions that compel states to ensure respect of the treaty provisions; this is the case of international humanitarian law rules, which have been constantly and brutally violated in Syria and Iraq.74
