Well, the head of the U.S. Central Command General Joseph Votel says that we need more troops in Afghanistan: Afghanistan-require-more-troops
This is not a particularly surprising statement. We currently have 8,400 there. This does not include U.S. contractors, U.S. police trainers and such, which still have a reduced presence there. I wonder what the proposed level will be. Last month the U.S. Afghanistan commander General John Nicholson said several thousand more troops were needed.
Anyhow, this is not a surprising conclusion. See America’s Modern Wars, in particular the chapter on Afghanistan; although the focus of our analysis was the number of troops required to fight an insurgency, vice the number of foreign trainers needed to support the indigenous troops fighting an insurgency.
I am guessing as both Nicholson and Votel have said it that it is now administration policy.
