The War Without an End

Twenty-five years after the September 11 attacks, the Twin Towers have vanished from New York’s skyline and the original architects of the terror are long dead. Yet, the conflict ignited that morning persists, not as a battlefield campaign, but as a permanent, self-renewing framework for managing national insecurity.

The War on Terror fundamentally destabilized the traditional logic of conflict. Historically, wars required a defined enemy, a clear geographic theater, and a specific condition for termination. By reframing war as a preemptive strike against the conditions that might produce future threats, the United States shifted from reactive defense to open-ended risk management. This evolution was codified in the 2001 Authorization for Use of Military Force and the 2002 National Security Strategy, which effectively detached military action from expiration dates or singular adversaries.

This shift created a structural bias toward force. When success is measured by the absence of an attack, any intervention is retrospectively validated, while inaction carries the risk of a catastrophic, televised failure. Consequently, political leaders face powerful incentives to favor kinetic action over diplomacy or intelligence-led policing. Data from organizations like the RAND Corporation suggest that military force is rarely the primary driver in dismantling terrorist groups, yet the post-9/11 architecture remains the default tool for addressing global instability. With post-9/11 war costs approaching $8 trillion, the most enduring legacy is a doctrine that lacks a defensible stopping rule. The central challenge for democratic states remains distinguishing between an immediate threat requiring destruction and a persistent risk that must be managed through resilience rather than perpetual war.
