Operation Enduring Freedom in Afghanistan (ISC Class 11 Political Science)
Updated 17 October 2026 · Fact-checked
After the 9/11 attacks of 2001 the USA demanded that the Taliban hand over Osama bin Laden and, when they refused, began Operation Enduring Freedom on 7 October 2001 with air strikes and the Northern Alliance. Kabul fell in November 2001, but an insurgency continued; bin Laden was killed in 2011 and the USA withdrew fully in August 2021, when the Taliban returned to power.
Notice the five key turning points: a war begun within weeks of 9/11 lasted twenty years and ended with the Taliban back in power.

Understand Operation Enduring Freedom in Afghanistan
Causes. (1) On 11 September 2001 al-Qaeda terrorists hijacked four airliners and attacked the World Trade Centre in New York and the Pentagon, killing nearly 3,000 people. (2) Al-Qaeda's leader Osama bin Laden was based in Afghanistan under the Taliban government's protection. (3) The USA demanded that the Taliban hand him over and close terrorist camps; they refused. (4) The USA declared a Global War on Terror; NATO invoked its collective defence clause for the first time; the UN Security Council recognised the right of self-defence.
Main events. Operation Enduring Freedom began on 7 October 2001 with US and British air strikes supporting the Afghan Northern Alliance. Kabul fell in November 2001 and the Taliban regime collapsed; Hamid Karzai led an interim government (December 2001). A NATO-led International Security Assistance Force helped secure the country but the Taliban regrouped and an insurgency continued. Suspected terrorists were held at Guantanamo Bay without trial, drawing criticism. Bin Laden was killed by US forces at Abbottabad, Pakistan, in May 2011. The US combat mission ended in 2014; after an agreement with the Taliban (2020) the USA withdrew completely in August 2021 and the Taliban returned to power.
Significance. It began with wide international support, unlike Iraq in 2003, but became the longest war in US history and ended without lasting stability. Historians and governments differ on assessments; positions should be attributed.
