Tech companies now occupy a position within conflict environments that previous generations of international law did not anticipate. Military communications rely on commercial satellite systems, intelligence analysis often depends upon privately developed artificial intelligence tools, and national cyber defence frequently involves cooperation with private cybersecurity firms. Armed conflict therefore operates through infrastructure that exists outside direct state ownership. Legal frameworks governing warfare continue to emphasise state responsibility and military command structures, yet operational capability increasingly depends upon corporate systems that sit beyond traditional defence institutions. This reality raises difficult questions about the concentration of strategic authority within private actors whose governance structures are commercial rather than political. My latest newsletter emphasises that the relationship between corporate technology and armed conflict represents one of the most challenging legal issues facing public international law today.
