US, Taliban talks on prisoner swap?

I read this news article online on MSN.com titled US, Taliban talks on prisoner swap falter. I am amazed that America is even talking to Terrorists. These inhuman people should be eliminated and not negotiated with. The Taliban by far is one of the most cruel militias in the world and they pose a threat to the human race itself. They wouldn't bat an eyelid before taking the lives of innocent civilians including children and women. I don't think their cadres should be shown any mercy, let alone the respect they are getting from the most powerful country in the world.

I wonder why America is doing this. They should simply issue a counter threat: "For every American soldier killed in captivity by the Taliban, US will eliminate a 100 Taliban operators on field and in prison." This will ensure elimination of this nemesis on the earth. In order to establish civil society across the world, thugs like these should be taken out.
