Abstract
The temporal boundaries of the international rules governing military force are myopic. By focusing only on the initiation and conduct of war, the legal dichotomy between Jus Ad Bellum and Jus In Bello fails to address the critical role of peacetime military preparations in shaping future conflicts. Disruptive military technologies, such as artificial intelligence and cyber offensive capabilities, only further underscore this deficiency. During their pre-war development, these technologies embed countless design choices, hardcoding into their software and user interfaces policy rationales, legal interpretations, and value judgments. Once deployed in battle, these choices have the potential to precondition warfighters and set in motion violations of international humanitarian law.
This Article highlights glaring inadequacies in how the U.N. Charter, international humanitarian law, and international criminal law currently regulate peacetime military preparations, particularly those involving disruptive technologies. The Article juxtaposes these normative gaps with a growing literature in moral philosophy and theology advocating for Jus Ante Bellum (just preparation for war) as a new limb in the Just War Theory model. By reimagining international law’s temporalities, Jus Ante Bellum offers a proactive framework for addressing the risks posed by the development of disruptive military technologies. Without this recalibration, international law will continue to cede regulatory authority to the silent decisions made in the server farms of defense contractors and the fortified war rooms of central command, where algorithms and military strategies converge to dictate the contours of conflict long before it even begins.
