Not a fix, but...
99.9% of Afghanis are Muslim. I think it is time the U.S. remind the Muslim nations of this and demand to see some of the peaceful intentions they keep telling us exist in Islam. If anything else, we should at least expose the fraud that somehow Islam is some peaceful force that can be used by people to in learning how to live together. It's a crock, we should label it a crock, and we should advertise it as a crock of shit.
I'm not enthusiastic about letting any of the Taliban zealots live. We should in no way encourage any deals that allow them to leave Afghanistan with their boots on. Wherever that misbegotten lot wind up and still alive, they will continue to cause problems for us.
I don't think there is a way for us or any other outside group to govern Afghanistan. Pakistan tried, but could only succeed by using the Taliban as proxies. The tribal leaders are living life 20 centuries ago, the whole concept of living together to get enough development to afford swimming pools, brew pubs, and vapid television shows is beyond their ken. They are only interested in power and to make sure their name is forever etched in the foreheads of their enemies. How does one fix that? If any modern groups should have been able to get over it, it would have been the Israelis and Palastinians, and we see how far they've come.
The U.N. has no teeth, they'd be lambs in slaughter if they were allowed to "keep the peace" in Afghanistan. We might think to buy peace by offering rewards to those willing to accede to live with their neighbors. But then their neighbors would get jealous, so we'd have to buy them too. And in 10 years, we'd have a welfare country fighting over the spoils we deal out.
In short, I don't think there is a solution. Maybe give them all enough arms to be really dangerous, seal the borders, and tell'em we'll be back when they have killed off each and everyone one of their Muslim brothers.
