CYBER WARFARE AND THE APPLICATION OF INTERNATIONAL HUMANITARIAN LAW: A LEGAL VACUUM?

Abstract

The integration of cyberspace into the modern battlefield has generated a paradigm shift in the character and conduct of warfare. It presents profound challenges to the established international legal order. In this context, the applicability of International Humanitarian Law (IHL) has been subject to intense debate, leading to assertions that a "legal vacuum" exists in this new and unregulated domain. This paper expostulates that such claims, while reflecting genuine operational and definitional challenges, are conceptually linear and detached from the doctrinal reality of IHL's universal applicability. IHL, with its inherent adaptive nature, is universally applicable (lex lata) to cyber operations during armed conflict, a principle firmly affirmed by the International Court of Justice (ICJ, 1996). However, the defining characteristics of cyber warfare, in particular its non kinetic nature, the pervasive anonymity it affords actors, and the deep structural entanglement of civilian and military networks, critically strain the practical application of cardinal IHL principles, such as distinction, proportionality, and the very definition of an "attack." This research, therefore, argues that the core challenge is not the absence of law, but a profound functional and interpretive gap in its implementation and enforcement. This gap, exacerbated by the strategic reluctance of major cyber powers to develop binding normative frameworks, creates a "legal labyrinth" of ambiguity rather than a true vacuum. While influential scholarly frameworks like the Tallinn Manual 2.0 (Schmitt, 2017) provide critical interpretive guidance, their non binding nature underscores the political inertia that prevents the emergence of concrete legal clarity and state practice. This study, therefore, takes a cursory examination of the security and humanitarian implications emanating from this core ambiguity, concluding that the international community's collective failure to bridge this interpretative gap poses a far larger threat to civilian protection and international security than the acknowledged difficulties of applying existing law to novel technologies.
