Twenty-five years after the September 11th terrorist attacks, the United States' "war on terror" is being re-evaluated, with critics arguing that the costly global campaign has yielded limited success beyond preventing another major attack on U.S. soil, while inadvertently fueling new forms of Islamist extremism and destabilizing regions.
The initial response to the 9/11 attacks in 2001 saw an unprecedented global rallying of support for the United States, including the invocation of NATO's Article 5. The swift U.S.-led assault on Afghanistan, with significant British involvement, dismantled Al Qaeda's training camps and ousted the Taliban from power.
However, the narrative shifted with the decision to launch the invasion of Iraq in 2003. This move, based on unproven claims of links between Saddam Hussein's regime and Al Qaeda, and the presence of weapons of mass destruction, is now widely seen as a pivotal error. The ensuing insurgency and civil war in Iraq not only claimed hundreds of thousands of lives and cost trillions of dollars but also served as a crucible for a new generation of Islamist terrorists, including the eventual rise of the Islamic State.
"The Iraq invasion is when it all started to go wrong for America's war on terror," notes Andrew Neil in his analysis. "Far from being the death knell of Islamist terror, Iraq gave it fresh impetus as all manner of jihadists and warlords piled in to take on the invaders and pursue their own vicious agendas in the general chaos."
The war on terror has spanned four presidencies, with each administration grappling with its complex and often intractable challenges. While Barack Obama sought to reduce foreign entanglements, he faced troop surges in Afghanistan and a mishandled response in Syria. Donald Trump, despite a base that opposed "forever wars," continued drone strikes and special operations across multiple countries and escalated tensions with Iran.
The financial cost of the war on terror is estimated to be around $6 trillion, with nearly 4,500 U.S. lives lost in Iraq alone, alongside significant casualties in Afghanistan and other theaters of conflict. The conflict has also been criticized for tactics that damaged America's global reputation, such as enhanced interrogation, extraordinary rendition, and the establishment of black sites.
Al Qaeda, though its core leadership has been degraded with the deaths of Osama bin Laden and his successor, has evolved into a franchise model, with affiliated groups operating in various regions, including East Africa and the Sahel. U.S. intelligence suggests these groups possess significant capabilities and resources, with some experts fearing the re-establishment of terrorist cells.
Furthermore, the Taliban has returned to power in Afghanistan, a country once again described as riddled with jihadists. The chaotic U.S. withdrawal in 2021, a decision inherited from the Trump administration, underscored the long-term challenges in the region. Al Qaeda's current leadership is reportedly based in Afghanistan, operating with the Taliban's support, and U.S. intelligence indicates that hundreds of terrorists have received training in Afghan camps.
Despite the immense expenditure of lives and resources, the "serpent now has many heads," and terrorism has not been defeated. The long-term implications of this enduring conflict continue to unfold, raising questions about the ultimate achievements and enduring consequences of the United States' global counter-terrorism strategy.
