Fuchs,

Your entire scenario rests on the assumption that increasing troop levels in response to our casualties (combined with an IO campaign) would discourage the Taliban or Afghans from fighting. That's a bad assumption.

It further rests on the assumption that the people in the US and other coalition countries would accept such a "strategy" for the commitment of forces. That is at least a questionable assumption if not downright politically impossible.

Finally, had your calculus been instituted at the beginning, it would have added about 33k troops since 2001. We now have about three times that number current in Afghanistan and the Taliban don't seem very discouraged.
