In fairness, sending more troops to Afghanistan has a certain logic to it because it is apparent that we cannot achieve our mission there at the current troop level.  However, sending more troops is also something of the right answer to the wrong question.  While it is clear that staying the course in Afghanistan is not going to lead to swift victory and soon to troop reduction, it is far from obvious that increasing the number of troops there will achieve this goal either.  Instead both these options will almost certainly lead to a commitment to U.S. involvement in the region that has no clear end, and which very likely means an expansion of our role and presence beyond Afghanistan in ways, and with implications, that we cannot fully anticipate.
