I'm not saying there isnt a lot to what you say. There is a middle ground at some point and there are costs vs gains ALWAYS. But I cant help but see, we had a very few people over there only 3,000 at most, in the entire country and it was helping them hold it together, so obviously there were Afghanis who had the will to work with us and trying to do it for themselves but obviously they were just not strong enough yet. I cant see how providing logistics and technical support was such a bad thing. Our presence there I think was also symbolic of our resolve and that along with the Afghan military seemed to be enough to keep the Taliban back.
I'm not convinced as you are that those people all want to remain backwards. They are just facing the Taliban who are actually a minority and made up of different peoples anyway. They are just savages.
