The Unwinable War on Terror After Two Decades

Twenty-five years after the attacks of September 11, 2001, the United States faces a sobering reckoning regarding its global counterterrorism strategy. President George W. Bush pledged to find, stop, and defeat every terrorist group of global reach, a standard that experts now argue was impossible from the outset. This framing set the stage for two decades of sustained military engagement across multiple continents, resulting in significant loss of life and financial resources without achieving a definitive victory.

The human and economic toll of these conflicts is staggering. Approximately seven thousand American service members have died in these campaigns, a number that exceeds the casualties of the original 9/11 attacks. According to data cited by the Costs of War project at Brown University, nearly one million people have been killed directly as a result of conflicts in Afghanistan, Iraq, Syria, Pakistan, and Yemen, with civilians accounting for roughly half of those deaths. The financial burden, measured in trillions of dollars, continues to shape U.S. foreign policy and budget priorities.

Defining an Impossible Standard

Colin Clarke, executive director of the Soufan Center, suggests that the U.S. set itself up to fail by defining the war in abstract terms. By targeting the concept of terrorism rather than specific organizations like Al Qaeda, the conflict became inherently unendable. Clarke notes that the U.S. has a tendency to wage war on broad societal issues, such as poverty or crime, which lack clear endpoints. This approach transformed a specific security threat into a perpetual state of emergency.

Bruce Hoffman, a professor at Georgetown University, agrees that the goal was unattainable. While the U.S. has successfully prevented another catastrophic domestic attack for over two decades, this is distinct from winning a war. Hoffman argues that victory would have required the total defeat of Al Qaeda and the triumph over its ideological narrative, both of which the U.S. has failed to achieve. The reorganization of national security agencies and improved coordination between local and federal levels have mitigated threats, but they have not eliminated the root causes of extremism.

Context of the Afghan Conflict

The origins of this strategy are rooted in the conditions in Afghanistan in the early 2000s. Under Taliban rule, the country faced extreme poverty, with per-capita GDP under two hundred dollars and widespread illiteracy. The regime relied heavily on opium production for revenue, and Al Qaeda operated with relative freedom. Journalists visiting the region at the time documented the dire living conditions, including orphanages where children were crowded into small rooms. The subsequent military intervention, which helped topple the Taliban, marked the beginning of a long and complex engagement in a region with deep-seated structural issues.

Forward Challenges in the Middle East

The current geopolitical landscape reflects the ongoing nature of these conflicts. In 2025, the United States, alongside Israel, has launched new operations in the Middle East, this time targeting Iran. This expansion indicates that the struggle against extremism is not receding but evolving. As noted in reporting by GN geopolitics/terror (en-US), the U.S. has spent nearly the entire twenty-first century engaged in conflicts with multiplying forms of extremism. The consensus among experts remains that without a fundamental shift in strategy, the U.S. will continue to face a war it cannot win.
