This paper outlines the current state of play in political warfare, identifies emerging threats, and proposes potential policy responses. It argues for greater information sharing mechanisms between trans-Atlantic governments and the private sector, greater information security and transparency, and greater investments in research and development on AI and computational propaganda. As authoritarian regimes seek to undermine democratic institutions, Western societies must harness their current— though fleeting—competitive advantage in technology to prepare for the next great leap forward in political warfare.
