Dude, that's not gonna work. What do you think weve been doing this whole time? These tribes couldnt give a rats ass about Afghanistan as a whole. They are just looking out for themselves as theyve done for thousands of years.
Taliban really isnt even the issue. They dont care about attacking the United States. They just want control of Afghanistan and money. Alqaeda is the problem.
There are always going to be terrorists organizations and we will never be able to rid them all. Sometimes its best to just leave some things alone
