War in Afghanistan (2001–2021) was a major international armed conflict triggered by the September 11 attacks and spanning two decades. The conflict began with a United States-led invasion to dismantle al-Qaeda and remove the Taliban government from power, which had harbored the terrorist group. Following initial military success, the war evolved into a protracted counterinsurgency and nation-building effort by the ISAF and later NATO forces, supporting the nascent Islamic Republic of Afghanistan, before culminating in the 2021 Taliban offensive and the fall of Kabul.
Background and causes
The immediate catalyst for the war was the September 11 attacks, planned and executed by the al-Qaeda network operating from within Afghanistan. The Taliban, led by Mullah Omar, refused United States demands to extradite Osama bin Laden and dismantle al-Qaeda camps. This refusal followed years of Taliban control after the Afghan Civil War, during which they provided sanctuary to al-Qaeda. The United Nations Security Council had previously imposed sanctions on the Taliban regime via United Nations Security Council Resolution 1267.
Invasion and initial operations (2001–2002)
Operation Enduring Freedom commenced on 7 October 2001 with airstrikes and cruise missile attacks. The United States and the United Kingdom partnered with the Northern Alliance, an Afghan opposition group led by commanders like Mohammed Fahim and Abdul Rashid Dostum. Key early battles included the Siege of Kunduz and the Battle of Tora Bora. The Fall of Kabul in November 2001 led to the Taliban's collapse, and the Bonn Agreement established the Afghan Interim Administration under Hamid Karzai.
ISAF stabilization and Taliban resurgence (2002–2008)
The ISAF, authorized by United Nations Security Council Resolution 1386, initially secured Kabul. The mission expanded nationally, with leadership rotating among nations like the United Kingdom, Germany, and Canada. The Taliban reorganized in Pakistan's tribal areas, launching an insurgency with tactics like IEDs and suicide bombings. Major combat operations included the Battle of Panjwaii and the Battle of Musa Qala, as violence escalated significantly after 2006.
US troop surge and transition (2009–2014)
President Barack Obama ordered a troop surge, deploying over 30,000 additional United States soldiers. A major offensive, the Battle of Marjah, was followed by the larger Battle of Kandahar. The United States conducted the raid that killed Osama bin Laden in Abbottabad in 2011. The ISAF transitioned to a support role in 2014, handing security leadership to the Afghan National Security Forces as outlined at the 2012 Chicago Summit.
NATO Resolute Support and stalemate (2015–2020)
The NATO-led Resolute Support Mission began in 2015, focusing on training and advising. The Taliban made significant territorial gains, contesting districts and provincial capitals like Kunduz. The United States increased airstrikes and deployed additional advisers under President Donald Trump, whose administration also engaged in peace talks with the Taliban in Doha. The Islamic State – Khorasan Province emerged as a rival extremist group, conducting attacks such as the 2020 Kabul University attack.
Withdrawal and Taliban offensive (2020–2021)
The United States and Taliban signed the Doha Agreement in February 2020, setting a conditions-based withdrawal timeline. President Joe Biden announced a full withdrawal by September 2021. The Afghan National Army collapsed as the Taliban launched a rapid offensive, capturing major cities including Kandahar, Herat, and Mazar-i-Sharif. The fall of Kabul on 15 August 2021 precipitated a chaotic evacuation from Hamid Karzai International Airport.
Aftermath and legacy
The Taliban declared the restoration of the Islamic Emirate of Afghanistan. The war resulted in extensive casualties among Afghan civilians, Afghan National Security Forces, and ISAF personnel, including over 2,400 United States military deaths. The conflict spurred a global refugee crisis and prompted investigations like the Afghanistan Papers. The rapid collapse of the Islamic Republic of Afghanistan raised profound questions about the efficacy of two decades of international intervention and counterinsurgency strategy.
