This article considers the positive evolution of international law in the past century, and the emergence of a rules-based multilateral system under the UN Charter, which has, inter alia, enabled formerly colonised peoples to exercise their right to self-determination and prohibited the use of force in international relations. The author reaffirms his faith in the ability of international law to provide a common language for the international community to face successfully common challenges, such as poverty, global warming, and the protection of privacy rights in the era of social media and artificial intelligence. Looking beyond traditional beneficiaries and duty-bearers of international obligations, the author makes a case for all actors to engage in respecting, upholding and promoting international law.
