Possibilities of Taliban Inclusion

According Anatel Lieven, a professor in the War Studies Department of King's College London, the Taliban may be willing to cut its ties to al-Qaeda for a stake in the politics of Afghanistan after the U.S> troops pull out, perhaps even to "US bases and military advisers after 2014" (FT). The question though, is how big of a stake do they want? And what exactly is the political landscape that the Talibans are imagining? Also, how will Karzai leave?
