This article explores the systemic impact of digitalization on the use of force regime. It identifies two types of impact: (i) legal uncertainty; and (ii) the replacement of international law. The article discusses legal uncertainty in relation to the content of the rules on the use of force and their application to digital uses of force as well as in relation to the facts that underpin digital uses of force. It then goes on to discuss the replacement of international law as a regulatory tool of the use of force by considering the impact of digitalization on the creation of customary law, legal personhood, and international law’s regulatory modality. The article’s findings are not limited to the impact of digitalization on the use of force regime but extend to international law in general.
