Interview with an embedded Journalist with Taliban:
Significant points are (1) Whatever happens in Afghanistan, but what about Pakistan? It too will need to be countered to get a solution of Afghanistan, and (2) There'll have to be an ethnic cleansing on the lines of Baghdad in Kabul, and the Pushtuns in rest of Afghanistan will need to be excluded from voting as the Sunnis in Iraq.
This is the solution apparently being seriously considered in the US line of thought.
Just killing brown people will not work as the gentleman says, International troops must withdraw. There's no other solution.
