Abstract
As artificial intelligence reshapes the modern battlefield, Lethal Autonomous Weapons Systems (LAWS) have ignited intense debate within International Humanitarian Law (IHL). This article critically examines the intersection of algorithmic warfare and the fundamental IHL principle of proportionality, which strictly prohibits attacks expected to cause incidental loss of civilian life excessive in relation to the concrete and direct military advantage anticipated. The authors argue that current machine learning models, despite their superiority in specific target recognition, lack the contextual nuance, ethical intuition, and qualitative human judgment requisite for complex proportionality assessments in dynamic combat environments. By meticulously evaluating the Geneva Conventions and their Additional Protocols, the paper exposes a profound "accountability gap." When an autonomous system inevitably violates the proportionality threshold—resulting in a war crime—the traditional legal doctrines of command responsibility and individual *mens rea* (criminal intent) disintegrate, rendering the prosecution of human operators or software developers highly problematic under the Rome Statute of the International Criminal Court. Furthermore, the authors invoke the Martens Clause, asserting that delegating life-and-death decisions to deterministic code fundamentally violates the dictates of the public conscience and the inherent dignity of human life. The article critically assesses the ongoing, yet stalled, diplomatic negotiations within the Convention on Certain Conventional Weapons (CCW) framework. The authors conclude by urgently advocating for a preemptive, legally binding international treaty that mandates "meaningful human control" over the critical functions of selecting and engaging targets, arguing that the qualitative legal standards of IHL can never be fully translated into quantitative algorithmic code.
