These people will revert to type.
That is the only scenario. Too much has to be de programmed for them to step into the 21st century.
They will still produce/smuggle opium
They will still sell their daughters
They will still settle all/any disagreements with a rifle
They will still hate/distrust any non-Muslim
They will still change sides at a whim
They will still appease the Taliban
They will still be poor, backward and violent. Nothing will change. EVER
I even think 7th century is too advanced for Afghanistan. Hell you can resurrect Alexander the Great and he would recognize the place except for the Islam.
