The field of security studies has long been defined by great power politics, interstate conflict, and traditional military threats. However, shifts in the global balance of power, the rising influence of non-state actors, and the increasing urgency of nontraditional threats—such as climate change, infectious disease, biological weapons, and the risks associated with artificial intelligence—are challenging key assumptions in the field. In addition, security studies institutions are facing major funding cuts as U.S. government support for academic research and foundation support for security studies decline.
