A timeline of the US military presence in Afghanistan
During the nearly 18 years since the United States went to war in Afghanistan, the number of U.S. troops there reached as high as 100,000 and then plummeted after the 2011 killing of al-Qaida leader Osama bin Laden in neighboring Pakistan to the some 14,000 today. Now President Donald Trump has abruptly called off negotiations between the U.S. and the Taliban, the insurgent group toppled in the 2001 U.S.-led invasion, on a deal that would begin a final troop pullout as part of ending America’s longest war.
A timeline of the U.S. military presence in Afghanistan:
___
Oct. 7, 2001: President George W. Bush announces that U.S. and British troops have begun striking Afghanistan for harboring the al-Qaida terrorists blamed for the Sept. 11 attacks. The massive air campaign initially targets Taliban troops, training camps and air defenses.
___
November 2001: 1,300 American troops are in the country as commandos and ground troops, mostly Marines, begin to arrive.

December 2001: The U.S. force grows to 2,500 as troops scour the mountainous Tora Bora region looking for al-Qaida leader Osama bin Laden. The Taliban is ousted and an interim Afghan government is established.
___
March 2002: 7,200 U.S. troops are in Afghanistan as Americans lead allied Afghan forces in the largest ground assault of the war to date.
___
December 2002: The U.S. ends the year with about 9,700 troops deployed, mostly going after Taliban insurgents.
___
December 2003: The year ends with about 13,100 troops in Afghanistan.

___
December 2006: Attention has shifted to the escalating war in Iraq; the force in Afghanistan remains just over 20,000.

___
May 2009: As fighting in Afghanistan becomes more intense, the number of U.S. troops surpasses 50,000.
___
December 2009: Troops now number more than 67,000, and the situation is deteriorating, with escalating violence and more service members killed. Obama orders in another 33,000 troops to battle al-Qaida militants and a resurgent Taliban.
___
August 2010: The U.S. force reaches 100,000.
___
May 2011: Bin Laden is found hiding in neighboring Pakistan and killed in a U.S. special operations raid. There are still about 100,000 troops in Afghanistan.
___
June 2011: Saying the U.S. is meeting its goals in Afghanistan, Obama announces his withdrawal plan: Bring home 10,000 troops by the end of 2011, and continue at a steady pace until handing over security responsibilities to the Afghans by 2014.
___
September 2012: Troop levels down to 77,000.

December 2013: Down to 46,000 troops, the slow withdrawal continues.

May 2014: Obama announces his plan to pull virtually all U.S. troops out of Afghanistan by the end of 2016, when his second term in office will be drawing to a close.

___
Oct. 15, 2015: In a reversal, Obama says the situation is too fragile for the American military to leave. He announces plans to keep the current force of about 9,800 in place through most of 2016 to continue counterterrorism missions and advise Afghans battling a resurgent Taliban. The plan is for the number to decrease to about 5,500 troops by December 2016.
___
July 6, 2016: Saying the security situation in Afghanistan “remains precarious,” Obama announces that instead of dropping the U.S. troop level to 5,500, he will keep it at about 8,400 through the end of his term on Jan. 20, 2017. He said his successor can determine the next move.
___
Aug. 21, 2017: Trump warns against a “hasty withdrawal” from Afghanistan, saying that “conditions on the ground, not arbitrary timetables, will guide our strategy from now on.” Weeks later it is confirmed that additional troops will be deployed, eventually bringing the number to about 14,000.
