Secretary Gates talks about the Taliban being routed from Afghanistan. Musa Qala is the area of Afghanistan that U.S. and Afghanistan forces concentrated on in the fall before the winter weather got too bad for sustained operations. I know from my vantage point at the Combined Air Operations Center at Al-Udeid that there was a heck of lot going on in Musa Qala. But I also know that Musa Qala is located in the south western part of the country, so it seems pretty unlikely that the operations there routed the Taliban from Afghanistan. From a purely geographic stand-point, it seems more likely that any Taliban that survived the operations in Musa Qala were more likely scattered within Afghanistan, rather than sent off to Pakistan or Iran.
