The withdrawal of United States troops from Afghanistan describes the drawdown of United States Armed Forces in the Afghanistan war and the plans after its post-2014 presence when most combat troops had left Afghanistan at the end of 2014.

NATO had planned on maintaining 13,000 troops including 9,800 Americans in an advisory and counter-terrorism capacity in Afghanistan during the 2015 phase of the War in Afghanistan and they were expected to maintain a presence inside Afghanistan until well after the end of 2016. In July 2016, in light of the deteriorating security conditions, the US postponed the withdrawal until December 2016 and decided to maintain a force of 8,400 troops in 4 garrisons (Kabul, Kandahar, Bagram and Jalalabad) indefinitely due to Taliban resurgence attempt after the Battle of Kunduz. The withdrawal was completed in December 2016 leaving behind 8,400 troops.

Background 2009 U.S. troops increase under the Obama Administration Troop levels remained roughly constant under U.S. president Barack Obama's predecessor, former president George W. Bush, with around 30,000 American troops deployed in Afghanistan. In January, about 3,000 U.S. soldiers from the 3rd Brigade Combat Team of the 10th Mountain Division moved into the provinces of Logar and Wardak. The troops were the first wave of an expected surge of reinforcements originally ordered by George W. Bush and increased by Barack Obama.

On 17 February 2009, Barack Obama ordered 17,000 more US troops be sent to Afghanistan to bolster security in the country and thereby boosted the 36,000 US troops already there by 50%. "This increase is necessary to stabilize a deteriorating situation in Afghanistan, which has not received the strategic attention, direction and resources it urgently requires," Obama said in a written statement. "The Taliban is resurgent in Afghanistan, and Al-Qaeda supports the insurgency and threatens America from its safe haven along the Pakistani border," Obama also said. He recognised "the extraordinary strain this deployment places on our troops and military families", but the deteriorating security situation in the region required "urgent attention and swift action". The new troop deployment was expected to include 8,000 U.S. Marines from Camp Lejeune, North Carolina, 4,000 U.S. Army troops from Fort Lewis, Washington and another 5,000 troops from an unspecified branch of the U.S. Armed Forces. Obama also said he was "absolutely convinced that you cannot solve the problem of Afghanistan, the Taliban, the spread of extremism in that region solely through military means."

A further decision on sending more troops came after the administration completed a broader review of Afghanistan policy. On 27 March 2009, Obama announced after an intense 60-day White House policy review, in which military commanders and diplomats, regional governments, partners, NATO allies, NGOs and aid organisations were consulted, a new strategy for Afghanistan and Pakistan. "So I want the American people to understand that we have a clear and focused goal: to disrupt, dismantle, and defeat al-Qaida in Pakistan and Afghanistan, and to prevent their return to either country in the future. That is the goal that must be achieved. That is a cause that could not be more just. And to the terrorists who oppose us, my message is the same: we will defeat you," Obama said. For this purpose Obama announced that he plans to further bolster American forces in Afghanistan, increase aid to Pakistan, and set strict standardslike levels of violence and casualties in Afghanistan, Pakistani attacks against insurgents and accounting for U.S. aidfor measuring progress in fighting Al Qaeda and the Taliban in both countries. Part of his strategy was the deployment of 4,000 U.S. troopsbeyond the additional 17,000 he authorized in February—to work as trainers and advisers to the Afghan army and police. The move was accompanied by a "surge" in US civilians to Afghanistan to help rebuild the country's infrastructure. In addition to the renewed focus on Afghanistan, the Obama administration was to step up pressure on Pakistan to tackle the al-Qaida and Taliban safe havens in the tribal areas along its border with Afghanistan. US military and civilian aid was to be increased. The last element of the policy was to try to engage Afghanistan's regional neighbours, including Russia and Iran, in helping to pacify Afghanistan.

"There is no imminent threat of the government being overthrown, but the Taliban has gained momentum," Obama said with respect to the 2009 situation in Afghanistan. "Al Qaeda has not reemerged in Afghanistan in the same numbers as before 9/11, but they retain their safe-havens along the border. And our forces lack the full support they need to effectively train and partner with Afghan Security Forces and better secure the population." On 1 December 2009, Obama therefore announced at The United States Military Academy in West Point that the U.S. will be sending 30,000 more troops to Afghanistan and set July 2011 as the date to begin pulling U.S. forces out of the country. Promising that he could "bring this war to a successful conclusion," Obama set out a strategy that would seek to reverse Taliban gains in large parts of Afghanistan, better protect the Afghan people, increase the pressure on Afghanistan to build its own military capacity and a more effective government and step up attacks on Al Qaeda in Pakistan. The president said the three core elements to the new strategy are "a military effort to create the conditions for a transition; a civilian surge that reinforces positive action; and an effective partnership with Pakistan." The overarching goal was to "disrupt, dismantle, and defeat al Qaeda in Afghanistan and Pakistan, and to prevent its capacity to threaten America and our allies in the future." The West Point Speech concluded a three-month review of war strategy. During the review, Obama asked for province-by-province assessments of the Taliban's strength, the effectiveness of provincial Afghan leaders and the overall security outlook to determine how quickly U.S. forces could leave certain regions. In the months leading up to his West Point speech, more precisely at a meeting with the Joint Chiefs of Staff on 30 October 2009 to discuss his troops surge plan, Obama stated that the Afghanistan War is an American war, but he doesn't want to it make an open-ended commitment. Obama also was livid that details of the 3 month Afghanistan War Review discussions were leaking out according to The New York Times. "What I'm not going to tolerate is you talking to the press outside of this room," he scolded his advisers. "It's a disservice to the process, to the country and to the men and women of the military." In addition to the 30,000 additional U.S. troops that Obama announced to deploy to Afghanistan Obama sent an additional 22,000 forces (which were earlier announced in 2009 (compare section above)) along with 11,000 troops that were authorized by his predecessor to Afghanistan.

2010 London Conference on Afghanistan and 2010 Afghanistan War Review During the London Conference on Afghanistan Afghanistan announced on 28 January 2010 its intention of taking charge of the "majority of operations in the insecure areas of Afghanistan within three years and taking responsibility for physical security within five years". This combined with the increase of Afghan military strength to 171,600 and police numbers to 134,000 by October 2011 would enable the United States could begin to transition U.S. troops out of Afghanistan in July 2011 according to US Secretary of State Hillary Clinton. "It's not an exit strategy, it's about assisting the Afghans" in taking responsibility for their own security, she explained.

Declaring significant progress in disrupting al-Qaeda and combatting the Taliban, Obama said on 16 December 2010 that the United States will start withdrawing U.S. troops from Afghanistan in July 2011. Obama said "we are on track to achieve our goals" in the Afghan war and to "start reducing our forces next July." He added the drawdown will "conclude in 2014." Obama appeared before reporters to announce the results of the Afghanistan war review, which was compiled from reports submitted by military, diplomatic and intelligence officials since mid-October 2010. The president had directed his national security staff to perform a "diagnostic" assessment of the December 2009 West point strategy after one year. They convened eight working-group and deputy-level meetings from 16 Nov through 1 Dec.. An interagency team also visited Afghanistan and Pakistan from 25 October through 4 November to discuss the situation with key leaders first-hand. The summary document of the review included no specifics as to the potential size or pace of withdrawal, making no assessment as to whether any milestones have been reached and leaving substantial wiggle room for future decisions. "As a result of our integrated efforts in 2010," the report said, "we are setting the conditions to begin transition to Afghan security lead in early 2011 and to begin a responsible, conditions-based U.S. troop reduction in July 2011." The review concluded that the military surge of 30,000 troops has been a success, saying it "reduced overall Taliban influence and arrested the momentum they had achieved in recent years in key parts of the country." It added, however, that successes remain "fragile and reversible."

2011 drawdown speech

On 22 June 2011, Obama addressed the nation from the White House and announced that 10,000 troops would be withdrawn by the end of 2011 and an additional 23,000 troops will leave the country by the summer of 2012. He said the drawdown would continue "at a steady pace" until the United States handed over security to the Afghan authorities in 2014. "We are starting this drawdown from a position of strength," Obama said. "Al Qaeda is under more pressure than at any time since 9/11." Asserting that the country that served as a base for 11 September 2001 attacks no longer represented a terrorist threat to the United States, Obama declared that the "tide of war is receding." The announced drawdown will leave approximately 68,000 U.S. troops in Afghanistan by the autumn of 2012 according to The Huffington Post, but Gen. John R. Allen, commander of the International Security Assistance Force (ISAF), said that 23,000 of the 88,000 U.S. troops currently in Afghanistan will be home by 30 September 2012 and thus 65,000 U.S. troops will remain in Afghanistan after the so-called Phase 2 drawdown.

2011–2012: Initial drawdown plans The U.S. drawdown in Afghanistan began 13 July 2011 when the first 650 U.S. troops left Afghanistan as part of Obama's planned drawdown. The units that left were two Army National Guard cavalry squadrons: the 1st Squadron, 134th Cavalry Regiment, based in Kabul, and the 1st Squadron, 113th Cavalry Regiment, which had been in neighboring Parwan province.

The United States and its NATO allies finalized agreements on 18 April 2012 to wind down the war in Afghanistan by formalizing three commitments: to move the Afghans gradually into a lead combat role; to keep some international troops in Afghanistan beyond 2014, and to pay billions of dollars a year to help support the Afghan security forces.
