America’s 20-Year Afghan War Began 25 Years Ago
Operation Enduring Freedom began 25 years ago with a rapid Taliban collapse, then expanded into a costly nation-building project that ended with the Taliban back in Kabul.
Twenty-five years ago, President George W. Bush announced the start of Operation Enduring Freedom. US and allied aircraft struck Taliban and al-Qaeda targets in Afghanistan on October 7, 2001, less than a month after the September 11 attacks. The opening campaign was fast. The war that followed lasted almost 20 years.
The immediate objective was clear: dismantle al-Qaeda’s base, remove the Taliban government that sheltered it and prevent Afghanistan from being used for another attack on the United States. American airpower, intelligence teams, special-operations forces and Afghan anti-Taliban fighters broke the regime’s conventional defenses. Kabul fell in November, and the Taliban government effectively collapsed within two months.
Calling that opening a complete success requires qualification. Al-Qaeda lost training camps and freedom of movement, but Osama bin Laden escaped from the Tora Bora area and was not killed until 2011 in Pakistan. Taliban leaders also survived, regrouped across the border and built an insurgency. Tactical victory did not eliminate the organizations Washington had gone to fight.
The mission then expanded. The United States and its partners attempted to build a centralized Afghan state, train national security forces, create courts and ministries, support elections, expand schooling and improve the status of women. Many Afghans gained education, health services and media freedoms. Those gains were real, even if they were uneven and later reversed.
The institutional weaknesses were real too. The Special Inspector General for Afghanistan Reconstruction documented corruption, “ghost” personnel, unrealistic timetables, poorly designed aid and programs measured by money spent rather than durable results. Washington spent about $145 billion on reconstruction and $837 billion on warfighting by 2021, according to SIGAR’s lessons report.
The human cost cannot be reduced to a slogan about waste. SIGAR counted 2,443 American service members and 1,144 allied personnel killed, with more than 20,000 US troops wounded. Tens of thousands of Afghan civilians, security personnel and fighters died. Families on every side continue to live with disability, displacement, trauma and unexploded ordnance.
The phrase “mission creep” captures part of the problem but can oversimplify it. Counterterrorism required local partners, intelligence and some form of government. Yet each necessary supporting task generated another commitment. Protecting a government required an army; sustaining that army required logistics and revenue; legitimizing the state required elections and services. The limited mission became dependent on a political order the coalition could not make self-sustaining.
Strategy also shifted repeatedly. Troop surges were followed by withdrawal deadlines. Negotiations with the Taliban excluded the Afghan government from key decisions. The 2020 Doha agreement set a US departure timetable, while the Afghan military remained dependent on foreign air support, contractors and money. When those supports disappeared, provincial capitals fell with startling speed.
The Taliban entered Kabul in August 2021 as President Ashraf Ghani fled. The final evacuation from the airport saved more than 120,000 people but was marked by chaos and an Islamic State bombing that killed 13 US service members and scores of Afghans. The collapse did not mean every 20-year achievement was fictional; it showed that many achievements depended on a system unable to survive without external backing.
The popular claim that the war “avenged” September 11 also deserves care. Military operations disrupted al-Qaeda and killed or captured numerous militants. But justice for a terrorist attack and the construction of a new Afghan society were different goals. Combining them allowed success to become permanently undefined.
Afghanistan’s lesson is not that military force never works. Force removed the Taliban government quickly and degraded al-Qaeda. The lesson is that battlefield dominance cannot substitute for a realistic political settlement, local legitimacy or an honest definition of what an outside power can sustain.
The anniversary also complicates simple judgments about the people who served. Soldiers and civilians could perform courageous, useful work inside a strategy that ultimately failed. Schools built, patients treated and attacks disrupted do not disappear from history because the government collapsed. Strategic accountability requires holding those human achievements and the larger institutional failure in view at the same time.
What to watch next
Watch US policy toward Taliban recognition, humanitarian aid, Afghan refugees and counterterrorism threats. The 25th anniversary is less a celebration or indictment than a warning: a war can win its opening campaign and still fail to secure its ultimate political aims.
