If I were able to brief the President on the current situation in Afghanistan, I would say this: Leave now. Maintain a small force of Special Operations men and Unmanned Aerial Vehicles (Predators etc) at Bagram Airbase. From there, potential terror training camps can be dealt with swiftly.
We no longer need a large force in Afghanistan, a country with no hope for achieving 20th century competence.
We won. We did what we needed to do, thus achieving strategic victory. Now our troops only present living targets. Al-Qaeda is an ever elongating shadow, badly defeated even as the media told us we were losing.
Let’s leave Afghanistan, whose dark age mindset and advancement cannot possibly be rectified in our lifetime.
