I've noticed that in almost every TL with mention to any occupation of Afghanistan that doesn't have anything to do with the Soviets or the current war, the Afghans put up a helluva lot of fight. Is there something in Afghan blood that gives them the balls to fight against occupiers that other countries don't? If not, I see this as either a misunderstanding of them or a simple nod to the current War in Afghanistan (which wouldn't make much sense if your TL is say, sometime Pre-WW2).
