There are models of government that could be used. One is the city state model based on ancient Greece. We all learned that ancient Greece was a Democracy. We also learned that ancient Greece could take on more powerful outside forces, at least until it got corrupt. What is less talked about is that they fought among themselves such as the Athenians vs the Spartans. England, China, India and Japan started out the same way (including fighting among themselves) but formed more stable governments later on. The idea would be to abandon the corrupt federal government of Afghanistan, which has little power outside its city anyways, and strengthen the power bases of the various tribes, especially those that aren’t wishy washy with the Taliban. The idea is that even though there would still be fighting in Afghanistan during our life time, the tribes would start to form various alliences to the point that Afghanistan turns into a confederacy and maybe then into a federal system the Afghans actually support.
