In this insight, I as a young constitutional scholar will offer you a pure constitutional perception and prism recently published by the leading constitutional journal Global Constitutionalism (GlobCon). There are comprehensive and impressive theoretical also empirical, practical dimensions of the problem and basically, it oriented towards the newest doctrine and approach recently enshrined in the international public law - Responsibility to Protect. I firmly believe that this source and prism of understanding will definitely enrich your intellectual horizon and you would smoothly tackle the challenge regarding paper elaboration.
