Between Borders And Bodies: Sovereignty, Universality, And The Crisis Of Enforcement In International Law, Aliaa Riad Hassanien Aliaa Riad

Theses and Dissertations

Atrocities such as genocide and war crimes persist not despite international law, but within its very structure. Although international law is designed to protect humanity, it repeatedly fails to do so due to its inability to enforce its most fundamental norms. In the absence of enforcement, the law exists—but merely stands still. This failure stems from the structural contradictions embedded in the system—specifically, the tension between the principles of sovereignty and universality. As a result, international law has become a selective, politicized, and ineffective framework. Incidents such as the Rwandan genocide and the civil wars in Syria and Sudan demonstrate …
