NATO leaders have endorsed plans to hand Afghan forces the lead for security across their country by mid-2013 while foreign troops will gradually switch their focus from combat to support mode.
In a Chicago summit declaration, US President Barack Obama and his 27 military allies confirmed plans to withdraw their combat troops by the end of 2014 and leave behind a training mission.
"The irreversible transition of full security responsibility from the International Security Assistance Force (ISAF) to the Afghan National Security Forces (ANSF) is on track for completion by the end of 2014," they said.
Afghan President Hamid Karzai announced last week that his forces were ready to take over security in several new provinces, putting them in charge of protecting 75 percent of Afghanistan's population.
"By mid-2013, when the fifth and final tranche of provinces starts transition, we will have reached an important milestone in our Lisbon roadmap, and the ANSF will be in the lead for security nationwide," the declaration said, referring to a 2010 NATO summit in Lisbon.
"At that milestone, as ISAF shifts from focusing primarily on combat increasingly to the provision of training, advice and assistance to the ANSF, ISAF will be able to ensure that the Afghans have the support they need as they adjust to their new increased responsibility," they said.
"We are gradually and responsibly drawing down our forces to complete the ISAF mission by 31 December 2014."
The 28 allies, who discussed Afghanistan over dinner at the American football Soldier Field late Sunday, were to meet with their 22 partners in the Afghan mission as well as Pakistani President Asif Ali Zardari on Monday.
Their declaration stated that the NATO-led combat mission would end by the end of 2014.
"NATO is ready to work towards establishing, at the request of the Government of the Islamic Republic of Afghanistan, a new post-2014 mission of a different nature in Afghanistan, to train, advise and assist the ANSF, including the Afghan Special Operations Forces.
"This will not be a combat mission. We task the (North Atlantic) Council to begin immediately work on the military planning process for the post-ISAF mission."
