A new report it is the taliban could make a comeback if the u. S. Pulls out of afghanistan. The intelligence published in the wash post said it could take three years to grow. Tom ackerman has moshing. A national estimate is a report which is a consensus of the 16 intelligence agencies on the outlook, their estimation of an outlook for a particular policy question, which probably is impending and in this case is the course of american posture in afghanistan, which may or may not have 34,000 or 10,000 or maybe zero troops by the end of 2014. It depends on the negotiations currently being conducted with the Afghan Government. Now, this is the report that youre talking about is actually a leak, and these reports, these nies are also classified but always emerge in the media as the product of a leak. You can be pretty confident that one side or another, which feels that the conclusions in this report favor their side of the arguments here in washington, that theyre responsible for this. In this case it sounds like its the civilian intelligence agencies which their voice comes through in this nie. As you can hear from the back and forth with the government of predz hamid karzai, the American Relations with the his government at least are very, very frigid right now, and there is the ongoing threat that the United States, if they do not conclude a Security Agreement with the government, and again, this is the outgoing government because karzai does not have another term. He cannot succeed into another term. That the United States is threatening the Afghan Government with just pulling out completely because theres no understanding as to the status of forces in afghanistan at the end of 2014. So the question here is for policy makers in the United States, how does this intelligence estimate, which talks about the taliban resurging not necessarily in kabul but in the provinces how much that would inform the way the American Administration should conduct itself in these negotiations with the afghans.
