You don't think there is a fuzzy line, if not a clear line, between the popularly supported Taliban as a government entity, and al Qaeda, a jihadist / terrorist organization?
I do not think the Taliban is widely supported. But even so, if they are trying to kill us, does that not make them an enemy just like a soldier or terrorist? And if so, then what is wrong about trying to kill members of those trying to kill you? We kill generals by snipers in war. Are you trying to say that if we know that a Taliban general (i.e. someone who directs military operations against us) we should not try to eliminate them?
Sounds really warped to me.
