Well, Boroda even if...IF... 150,000 is a correct number, it's a far, far cry from 500,000.
Further, given the nature of Afganistan's infrastructure, I doubt we'll be doing anywhere near as much in populated areas as we did in Iraq. (The first time; stay tuned.)
Beyond that, as others have already mentioned in this thread, your concern for the Afghan civilians is sort of touching... considering the mines that were disguised as children's toys that your country spread around a few years back.
And, of course, the gentle, humane treatment that the civilians of Grozny in particular and Chechnya as a whole come to mind as examples of what a truly compassionate State does when it seeks to "root out terrorism". BTW, are there ANY civilians left alive in Grozny? Must be a few... Russian certainly couldn't have killed them all yet, could they?
As for fighting on the Uzbekistan border, I would think the worst mistake the Taliban could make would be to concentrate troops. Anywhere. It's what a B-52 does best. I think it would seriously shorten the entire scenario if we COULD get the Taliban to concentrate troops. Dispersal is their best friend.
Well, won't be around the computer much this week.. enjoy to arguments!
