My intervention addresses the “external” relations of IR with another discipline - IL. The revolutionary developments in international relations, e.g. the rising role of the nonstate actor, the return of religion, the inter-connectedness between security and the economy, etc. have been challenging both the politics of international relations as well as the legal architecture of the regimes designed to assist politicians in navigating these politics. Consequently, they have pushed the disciplines of international relations and international law towards closer interaction.
