Probably it has to come down to improved intelligence. Use this to pin point individual targets. Sending in bombers and ground troops always seems to have a negative result.Either from collateral damage, abuse by ground forces or resentment of the native population to having occupying forces in their homes. It is never going to be a quick or easy task, which will result in negative publicity, because the media are always impatient for any news to report and will put any old crap on our screens to fill airtime.
