The 2020–2021 U.S. troop withdrawal from Afghanistan denotes the phased reduction and eventual removal of United States military personnel stationed in Afghanistan, spanning the period from the signing of the U.S.–Taliban Agreement in February 2020 through the final evacuation operations in August 2021.
Background
- In February 2020, under the administration of President Donald J. Trump, the United States and the Taliban signed the Doha Agreement (formally the “U.S.–Taliban Deal”), which stipulated that all U.S. forces would be withdrawn from Afghanistan within 14 months, contingent on the Taliban's commitments to prevent terrorist groups from using Afghan territory to threaten the United States and its allies, and to engage in intra‑Afghan negotiations.
- At the time of the agreement, approximately 13,800 U.S. military personnel were deployed in Afghanistan, primarily as part of the NATO‑led Resolute Support Mission.
Implementation (2020)
- Following the agreement, the United States began a deliberate drawdown, lowering troop levels to roughly 11,000 by mid‑2020.
- In September 2020, the U.S. announced a further reduction to 8,600 troops, focusing on advisory, intelligence, and counter‑terrorism missions while transferring many combat roles to Afghan National Security Forces (ANSF).
Implementation (2021)
- The Biden administration, which took office on 20 January 2021, confirmed its commitment to complete the withdrawal in accordance with the Doha timeline, while reviewing the security situation.
- In February 2021, the Department of Defense reported that U.S. forces in Afghanistan numbered about 2,500, the lowest level since the 2001 invasion.
- On 14 April 2021, President Joe Biden announced that the final U.S. combat troops would leave by 11 May 2021, with a limited residual force remaining for embassy security and counter‑terrorism.
- The rapid collapse of the Afghan government and security forces in August 2021 accelerated the timeline. The final U.S. flight out of Hamid Karzai International Airport occurred on 30 August 2021, completing the withdrawal of roughly 2,500 remaining personnel, including civilians and contractors.
Key Outcomes
- The withdrawal ended a nearly two‑decade U.S. military presence that began with the 2001 invasion.
- The departure coincided with the Taliban’s swift takeover of Kabul on 15 August 2021.
- The United States conducted a large‑scale evacuation operation, airlifting more than 120,000 people—including U.S. citizens, third‑country nationals, and vulnerable Afghans—between 14 August and 30 August 2021.
- The final drawdown left a residual U.S. diplomatic presence in Kabul, which was later evacuated after the Taliban seized control of the capital.
Significance
The 2020–2021 withdrawal is viewed as a pivotal moment in U.S. foreign‑policy history, marking the conclusion of direct American combat involvement in Afghanistan and prompting extensive analysis of nation‑building strategies, counter‑terrorism policies, and the geopolitical implications of the Taliban’s return to power.
