U.S. Military leaders are prepared to back Afghan President Hamid Karzai’s timeline for U.S. troop withdrawal, saying in roundtable meeting with reporters Monday that Afghan security forces should be able to handle the country’s security on their own by 2014.

Defense Secretary Robert Gates said the withdrawal timeline will discussed further at an upcoming NATO summit in Lisbon, Portugal at the end of the month…

Lt. Gen. William Caldwell, head of NATO’s training mission in Afghanistan, says he’ll need around 900 more trainers to get the Afghan forces ready in time. That’s roughly half of what he’s working with now and without them, Caldwell says, the goal won’t be met.

Critics say that by announcing this need for additional trainers two weeks before the NATO summit, the Obama administration is signaling member nations they’ll need to supply the forces.
