Your stupidity astounds me.
The Taliban was working with Bin Laden, and they are still terrorists, so yes, they are legitimate targets.
And there is no oil in Afghanistan, so the oil companies had nothing to do with Bergdahl's situation.
"The Taliban" was a political organization. We weren't fighting "The Taliban" in 2009. We were fighting tribal fights at that point, which was nothing to do with Bin Laden.
