It is a start that would have to be seen through for the next 30 yrs. You are dealing with a population that is 90% illiterate, they are tribal and the tribes bow to the war lords. What you are talking about is changing their entire culture, that would take generations.
As for pulling out and focusing on the cities, I am not in the military but it would seem that the Taliban would now own all in routes to the cities. We will be trying to defend the population while giving the Taliban all the area surrounding them. And then by the time they get to the cities the ROE pretty much prevent them from firing at them due to the civilian population.
