The tribes that constitute Afghanistan would have confounded Alexander if he had lived. They maintained an uneasy independence from the Caliphate, when it still existed. The Moguls didn't bother with them. They confounded the British Raj for 75 years, and then the Russians. They will confound the US as well, along with our allies, should we treat them like colonial underlings, unless we figure out how to do something the above-mentioned groups didn't.

The only ones -- the only ones -- who can enforce manditory education in Afghanistan are the Afghanis. Even they may have some trouble accomplishing this, as they have no tradition of a strong central government. We can provide them with the materials, and maybe even training, but they will have to do the rest.
