The piece is called 'Is latest massacre of Taliban futile?'
it's very hard to determine what was achieved by the Kajaki Dam battle, territorially, morally or in terms of winning hearts and minds.
The piece (title and excerpt above) being the write up by Alex Thomson on the Channel 4/News/International Politics page that you link us to, airsound, rather than the video of the filmed piece which is in turn linked from that. I make the contrast as there was no such reservation on the video
AFAIK, other than the end piece comment that both sides would have claimed success. The comment above is good Guardianesque woolly minded nonsense IMHO, the aim was not to win territory but to stop further T'ban encroachment towards the Dam, all war is immoral but sometimes it is also the least immoral course on offer, if the dam is lost to the T'ban then many tens of thousands of H's and M's would also be lost. A rather disappointing tag to what otherwise was an excellent item. Co-incidentally the dam defence was also the subject of last night's episode of Ross Kemp in Afghanistan, by the Royal Anglians who were readying themselves to hand over to the Royal Marines shown in this piece. The mature professionalism of such young men in both pieces was admirable, as was their cool courage. Respect!
