Why?
Nation building in Afghanistan? Forget it. It's not going to happen. The best thing we could do is pull out immediately and let the place go to hell on it's own. They don't call Afghanistan the "Graveyard of Empires" for nothing.
Going in to kick some Taliban butt and taking out Al Qaeda was a good mission, but hanging around and trying to run the place was dumb. It's not "run-able". Never has been. Never will be.
The Talibunnies LIKE having us there because it gives them someone to shoot at. If we leave, they'll go back to shooting at each other. Nothing will change.
Pakistan is a failed state held together by brute force, connivance, corruption and a smattering of Islamic fanaticism. Let China have the headaches.
This goes beyound Afghanistan
Right now the terrorists are hanging out in Pakistan just waiting to return to Afghanistan. And Pakistan has nukes...The last thing the world needs is al Qaeda with nukes.
We don't do anything to make the averge Pakistani's life any better, China does...That is why they don't need us.
