So the US was carpet bombing Baghdad with B52s, rpm? How about Kabul? Surely that is what you are suggesting, if you think the Russians have anything to learn from US anti-terrorist approach. You've got them completely arse over tit in the brutality stakes.
Killing innocent civilians to get at a paramilitary group only strengthens the support for them. That is a lesson that can be learnt from the French experience in Spain in 1809, for example, to the present day.
