Dispatching more troops to Afghanistan would be a monumental bet and probably a bad one, most likely a waste of lives and resources that might simply empower the Taliban. In particular, one of the most compelling arguments against more troops rests on this stunning trade-off: For the cost of a single additional soldier stationed in Afghanistan for one year, we could build roughly 20 schools there.What's the old Heinlein saying?
Itâ€™s hard to do the calculation precisely, but for the cost of 40,000 troops over a few years â€” well, we could just about turn every Afghan into a Ph.D.
Never try to teach a Pashtun tribesman to be a Ph.D. It wastes your time and it annoys the Pashtun tribesman.
