Definitions Matter: The Role of WMD in Shaping U.S. National Security Strategy

The document analyzes the historical development of the 'WMD paradigm' in the United States, which primarily equates WMD with chemical, biological, radiological, and nuclear (CBRN) weapons. The author argues that while this framework provided bureaucratic stability during the Cold War and post-9/11 era, it now creates a 'failure of imagination' by excluding other technologies—such as cyber weapons, drones, and synthetic biology—that can produce similar mass-casualty or mass-destruction effects. The text highlights a disconnect between the WMD paradigm and the actual historical record since 1990, noting that violent non-state actors often rely on conventional means and state actors frequently use CBRN for targeted assassinations or psychological impact rather than mass destruction.

• The U.S. national security approach to WMD has become a 'threat paradigm,' meaning it is a standard model of behavior that tests new ideas about emerging threats, often requiring a major catalyzing event to produce significant reorganization of priorities.
• The definition of WMD became tightly linked to CBRN (chemical, biological, radiological, and nuclear) weapons during the Cold War, leading to the creation of rigid international treaties and domestic bureaucratic structures that discourage broader thinking about evolving threats.
• Historical data since 2012 suggests that the actual impact of WMD use by non-state actors is lower than the perceived threat; for example, an estimated 1,061 people died worldwide from non-state actor chemical agent use over a forty-year period ending in 2012, while the 9/11 attacks using conventional means caused more deaths than WMD incidents over many decades.
• Recent state-level use of WMD has often deviated from the 'mass destruction' definition, focusing instead on targeted assassinations in 'gray zone warfare' or psychological terror, such as the use of VX nerve agent by North Korea in 2017 and Novichok by Russia in 2018.
• The current WMD paradigm fails to account for cyber weapons, which can cause massive economic and systemic destruction without direct physical casualties, as evidenced by the 2017 NotPetya attack that cost over ten billion dollars in damages.
• The author concludes that the U.S. government risks another 'failure of imagination' if it does not move beyond the WMD paradigm to consider a broader framework of 'mass effects' that includes emerging technologies like artificial intelligence, synthetic biology, and drones.
