Just last night, Secretary of State John Kerry announced a deal to keep some American troops in Afghanistan after next year's withdrawal. "The agreement will speak for itself when the agreement is approved…We have agreed on the language that would be submitted to a loya jirga, but they have to pass it." Today, the President of Afghanistan said it might not be signed until next year. It's all about the continued presence of some American soldiers after most foreign troops leave the country. Is this another of Hamid Karzai's diplomatic maneuvers? Will the traditional meeting of 2500 tribal elders that's meeting on Afghan security, approve the troop deal? How many soldiers are needed to hold off the Taliban and protect Afghanistan's regional interests, and how long will the US be willing to pay the bills?
