To be fair, US has decades of high tech warfare experience, institutions that study war and constantly research about it, has best infrastructure, excellent means to project power and has virtually unlimited resources.

The Afghans have no proper education system, no institutions other than local commanders directing their bunch of troops and have virtually no good infrastructure. They literally live among mountains and have no good networks for transportation.

I am giving the Afghans a lot of credit, because what I said about them is true. They won in spite of that.
