President Barack Obama is nearing a decision to add tens of thousands more troops to Afghanistan, though probably not quite the 40,000 sought by his top general there. The White House emphasized that the president hasn't made a decision yet about troop levels or other aspects of the revised U.S. strategy in Afghanistan. White House spokesman Robert Gibbs said the president would meet again Wednesday with key members of his foreign policy and military team but was unlikely to announce final plans for Afghanistan until late this month, when he returns from an extended diplomatic trip to Asia.
