There Is No Military Path to Victory in Afghanistan | The National Interest:
Nearly fifteen years and counting, the war in Afghanistan has become America’s longest. Airstrikes against the Taliban government, undertaken along with the British, commenced in October 2001. American ground troops, 1,300 in number, arrived there in November 2001. By 2010, there were one hundred thousand. A steady cutback started in 2011, pursuant to a decision by President Obama, though some 9,800 still remain, despite the responsibility for fighting the Taliban and securing the country having been transferred to the Afghans in June 2013.
