The following video is a rather excruciating example of why the mission to Afghanistan is a failure in it's stated goal. It's deadly, dangerous, and very demanding for all those who participate but most want to have meaning behind what they do... and for the soldiers and the Afganies... what are they risking their lives for?
For those who profit from the government's actions... this is certainly a success. So why should they stop?
I think the second part really delivers the message.
