Afghanistan & Pakistan Tribal Conflicts

Leave it to the BBC to come up with an excellent  summary of the situation along the Pakistan / Afghanistan border where the USA is about to invest a lot more blood and treasure in the fight with the Taleban and Al Queda and supporters in those regions.

Given the huge global  importance of this region it is amazing to me how little we tend to know about this area, though this BBC summary helps explain why things are anything but simple there.
