What Was the War on Terror?

Foreign Policy | Joseph Stieb

United States foreign policy entered a transitional era following the conclusion of the Global War on Terrorism, a defining post-9/11 operational framework that reshaped American global force projection and counterterrorism doctrine. Although major combat operations in Afghanistan and Iraq have concluded, the strategic consequences of two decades of expeditionary campaigns continue to dictate Washington's strategic posture.

The campaign fundamentally altered executive authority, intelligence integration, and posture across the Middle East and South Asia. Oversimplified historical narratives obscure the institutional adaptations and operational lessons produced during these conflict cycles. Counterterrorism demands evolved rapidly. Consequently, military planners now face the dual challenge of disengaging from counterinsurgency commitments while adapting doctrine for renewed great-power competition against near-peer adversaries in Europe and the Indo-Pacific. Assessing the true operational efficacy and structural legacies of the counterterrorism era remains critical for future force design, alliance management, and defense budgeting.

Comment

The institutionalisation of counterterrorism doctrine transformed the United States military from a broad-spectrum conventional force into a specialized target-centric apparatus centered on Joint Special Operations Command. Expeditionary operations prioritized rapid sensor-to-shooter cycles and decentralized intelligence fusion to eliminate non-state threat networks across dispersed theaters. This focus compressed decision cycles but systematically degraded heavy armored maneuver capabilities and large-scale operational planning across division and corps echelons.

This doctrinal pivot relied heavily on airborne intelligence, surveillance, and reconnaissance assets, such as MQ-9 Reaper platforms, operating in uncontested airspaces. Tactical units adapted their operational concepts to persistent aerial coverage rather than organic air defense or contested logistics management. Consequently, the reorientation toward near-peer pacing threats exposes structural gaps in electronic warfare countermeasures and integrated air defense capacity established during Operation Enduring Freedom.

Strategic Question for Discussion

If legacy counterterrorism capabilities built around Joint Special Operations Command are reallocated to counter near-peer threats, which operational friction—contested logistics or degraded electronic warfare defense—will pose the greater vulnerability for expeditionary forces?

The available evidence points toward contested logistics as the more immediate operational vulnerability when reallocating specialized units. While electronic warfare threats can be partially mitigated through passive emission control, Joint Special Operations Command's reliance on unhindered operational supply lines leaves forward units severely exposed in anti-access environments. Consequently, sustaining high-tempo dispersed strike operations without permissive airlift remains an unresolved doctrinal challenge.
