One question worth pondering is:

If militia forces in Afghanistan were able to outright defeat or frustrate the two greatest modern conventional militaries; how would the creation of a 3rd rate conventional military better secure Afghanistan against that same threat?

Or, said another way: What is the proper mix of security forces that the nation of Afghanistan needs for the threats they face?

One would think that a confederacy of militia forces, oriented more toward law enforcement vice attacking each other, with an added capability to deal with those external elements that come into the country conduct UW to incite and support insurgnecy would be most appropriate.

Often "mini-me" is probably not what is needed.
