Why We Are Really In Afghanistan

According to wikileaks documents on the Afghan war, we are killing a lot more civilians than we are letting on about. I keep hearing about deaths in Kandahar. Kandahar is right in the path of the Trans Afghan Pakistan pipeline. It would be interesting to see where these all of these civilians are being killed. Below is a map of the path of the Trans Afghan pipeline is going to go through Afghanistan.
A little wiki-blob about the pipeline (Why we are really in Afghanistan. It has nothing to do with Al Qaeda or BinLadin. That's all a lie.) This article starts long before 2002 but i just clipped the most recent developments to post here. If you would like to see the history of thie pipeline go to: http://en.wikipedia.org/wiki/Trans-Afghanistan_Pipeline
"The new deal on the pipeline was signed on 27 December 2002 by the leaders of Turkmenistan, Afghanistan and Pakistan. In 2005, the Asian Development Bank submitted the final version of a feasibility study designed by British company Penspen. ‘Since the US-led offensive that ousted the Taliban from power,’ reported Forbes in 2005, "the project has been revived and drawn strong US support" as it would allow the Central Asian republics to export energy to Western markets "without relying on Russian routes". Then-US Ambassador to Turkmenistan Ann Jacobsen noted that: "We are seriously looking at the project, and it is quite possible that American companies will join it." Due to increasing instability, the project has essentially stalled; construction of the Turkmen part was supposed to start in 2006, but the overall feasibility is questionable since the southern part of the Afghan section runs through territory which continues to be under de facto Taliban control."
(where most of the killing is going on.)
