The US Special Forces team operators working in Afghanistan for the last couple of years were not quite so picky, and from Robin Moore's account in The Hunt for Bin-Laden it appears that they have pretty good reason for feeling that way about some of those they've worked with to eliminate our common enemies.
There are others in *The Stan* who took a somewhat different approach that works better for me, but I am not about to sell short the abilities and dedication of those both working with us and opposing us. And they do know their own backyard exceedingly well.
